Works Great
Live in Virginia; can get very muggy here during the summer. Frankly, didn't expect much of the unit but was happily amazed at how much water it removes from the air -we have mostly been using it in our living room. In general it's been keeping the humidity level to 38-41%. We tried it in our bedroom over the weekend. It's over our garage so it can get quite warm with the heat rising. Started it when we left for church and amazed when we returned about 3 hours later - it was very cool and at one point it registered "lo" which I knew to mean the humidity level was below 35%. We are very satisifed with this item

Good as expected
I bought this for my trailer. In cold weather when camping we had humidity condensation on the bedroom wall above our heads in bed. I do not want mildew. I have only had this for several weeks now and it is now December, so I can't talk about summer. Currently I keep it 45 degrees in the trailer; it is 30 degrees outside. It uses 225 watts when the compressor is on and 35 watts when only the fan is running. The noise from the compressor is very low - almost hard to tell when it is on over the fan noise. The fan noise seems about normal, quiet, but not super quiet. I like the setting on % humidity going down to 40%. I have it set on 50%. It took perhaps 4 hours to lower the humidity from 70 to 50 (on the device meter). The other humidity meter I have reads about 57, but I think that is expected. My intent is simply to dry out the trailer as much as possible without going over board. The water container has not yet filled, but I'm sure I could put a leak proof connection on it. However, I set the AD400 in the shower, so I don't care if it spills. I like the size and the nice handle. I would have more to say about its features after using it for 6 months.

There are only two downsides to the unit. It is about one quarter the size of the unit it replaced so the bucket has to be emptied more often, and it doesn't completely shut off. The fan runs constantly circulating and filtering the air even when it is dry enough.

Best Choice for a mid-size dehumidifier
Works very well and is the quietest dehumidifier I could find. You can use it in a bedroom and not be bothered by noise. Takes the humidity out of the air to your selected level and has auto shutoff when bucket is full. Easy to carry or push from room to room and quite easy to use. Very pleased to have this unit, sure beats others I have had by a long shot, especially the much quieter operation.

When I purchased this item I thought will this small portable unit be able to handle my mom's basement that gets a lot of seepage. I can't believe how dry the basement is since turning it on. Got rid of all mildew smell and water. It is by far the best dehumidifer I have ever seen!

Highly recommend this Dehumidifier
Purchased NewAir AD-400 Dehumidifier last year, based on good reviews. Was so pleased with its performance, just purchased a second one to replace another dehumidifier purchased at a local home retail center that quit working after only 11 months. The NewAir unit is sleek, compact, and extremely quiet, unlike other brand dehumidifiers I have previously used. Bucket is somewhat difficult to empty when completely full, but not enough of a problem to keep me from highly recommending this unit.

This works so well!
I live in rainy Southeast Alaska (over 80" rainfall annually), and needed to get a dehumidifier that is simple and effective to use. I did try to get another brand, but found they didn't ship to Alaska. Anyway, I received word from the same company that supplied and deals with dehumidifiers to take a look at what NewAir had to offer in a similiar capacity model I was wanting. The price was right, and it had all the options I was wanting, and they shipped it to Alaska too! The unit works perfect! The instructions are simple to follow. The water tray is easy to remove, and we did accidently forget to remove the water tray once, but the auto shut off worked like it was designed to do. We keep the unit in our bedroom and it is quiet! My significant other is so happy with this unit, and if she's happy so am I. If it works in rainy SE Alaska, it will work for you too! - OH! Our heating usage went down too! Another benefit I almost forgot to mention too. It will mean less $$ to heat our home.

I purchased this product for my sons basement bedroom. The basement has always smelled musty and damp. I do have an older dehumidifier running in the main basement area, but it just didn't seem to keep up. I plugged in this product, and within 2 days, my basement smelled 100% better than it ever had! It amazes me how much water it removes from the air. It is relatively quiet, and very easy to use and clean. I would recommend this product for anyone looking for a medium-capacity dehumidifier.

We had sooo much water dripping down the walls and on the windows, we couldn't even see out the windows. In one of our bed rooms we started getting mold. It is amazing how well the dehumidifier has cut down on the water dripping down our walls, not to mention the mold!! I just wish I would have bought one years ago.

Love this little machine. My allergies are under control and I no longer suffer the dreaded morning coughing thanks to this machine. It is easy to move from room to room. I use the condensed water it pulls from room to water my plants the next morning and plan on using it in my motor home when we are traveling....(Gas prices may hinder that plan).

I bought the portable dehumidifier for my basement and it has worked great. Simple to setup. I can set the timer and go. It automatically shuts off when the container is full of water or you can run a hose to a drain and it empties on its own. Definitely a good buy and affordable.

I'm very pleased with my dehumidifier. It works great and is very quiet running. I'll be even happier when I get my husband to hook it up to a hose so I won't have to remember to empty it. I would recommend this product to all my friends and family.

Bought two of these. Have been using one in my ground floor garage area and the other in a ground floor bedroom/bathroom suite, both of which are slightly below grade. After the first week, the humidity had dropped a good 15%. Have been using them without hosing and the basin typically fills up on each after about 24 hours. Pretty quiet.

We us the NewAir Ad-400 in our 40 Ft Motorhome when it is in storage in our barn as well as when we are staying at an RV resort in the more humid parts of the country. The drain is either routed via a hose to a sink or we've installed a drain through the defroster vent so that it can be used in the front of the motorhome. It does a nice job of eliminating the musty smell caused by stale air, pet odors, higher temperatures and humidity at a fraction of the cost of running the main HVAC units. Good value for the money.

We purchased the NewAir AD-400 to use in our motorhome. After a couple of weeks of usage, it has kept the interior drier without the musty smell we've been getting when it sits for even a few days in our barn. The drain is routed to the sink which drains into a 70 gallon grey water tank which we'll empty every few weeks, if we don't use the motorhome. The setup was easy and the unit has worked very quickly to create a better environment in the motorhome.

Water. After reading customer reviews on this unit we decided to give it a try and we have been greatly impressed. We use it in our master bedroom and bath area, and I have been stunned by how many gallons of water we've dumped down the sink since we started using it. It runs quietly and actually helps our one-year old sleep better thanks to the white noise it provides. The room also feels and smells noticeably better. Thumbs up all the way around! If I could change one thing, I'd make the tank a little bigger but that's it.

This little guy really does an outstanding job pulling unwanted moisture out of the air. My damp, concrete floored and walled basement is much more comfortable and pleasant with the regulation of moisture in the air. It's easy to wheel around to get to all corners and damper areas.

Perfect unit for smaller areas. Needs to be emptied every 5-6 hours set @ 40% setting. You can attach a drain hose (not included), however, the smaller water recceptacle is easy to empty and not heavy. I have a townhome on a slab and with the extremely hot humid summer this year it has helped to reduce the use of my a/c by reducing the humidity. The unit is very quiet and has the added air ionizer. Just plug in set humidity and your in operation. Moves easily on it wheels and small enough to slide into a coat closet when not in use.

Because of all the wet weather this spring and summer, the basement was extremely humid and uncomfortable. Since it is occupied space, I needed to do something. This dehumidifier has done a wonderful job. I had to run it almost constantly for several days to bring the humidity levels down, but now I just need to run it for an hour 2 or 3 times a day. It's clean and quiet, and easy to operate. An excellent investment.

It was put to work as soon as we got it and has been working quietly and efficiently ever since. Each day, it condenses the 40 pint container full of water. That's 40 pints that's not hanging in the air and contributing to the dampness and rust potential in the basement. It's quiet,very portable, and so far, easy to use. The manual, while complete, seemed a little over-complicated in explaining how to use it. It's light-weight, attractive, and we have 3 kids living in the basement and it's never in the way or disturbing to them in any way. Thanks for this great product, and the fast service and delivery.

It also helps clean the air, I have a couple of dogs and a cat , thank you.

Started using it in the bedroom to take the swelling out of the door. Decided using it in the dining room would be better. Empty the bin twice a day. Humidity is still high. Have another unit in the basement I bought June 2010. It is continuous along with the breathe right unit. The humidity in northeastern Ohio has been high this summer. Hopefully, come fall it will be better. They're quiet units. On high speed a little noisier.

A very quiet dehumidifier. It's taking the place of my 70 pint that was very loud. It seems to be doing a good job. I had to give it a chance to catch up because my basement was very wet after my old one stopped working. One of the reasons I bought this one is that it should be so much cheaper to run.

The only thing that I had trouble with was the hose hook up. The brochure tells you to get a plastic hose with a 9mm inside diameter. Unfortunately, my hardware store didn't have any metric rulers. I guessed and brought home a 3/8" id plastic hose and it fit perfectly. Drains like a charm.

I recently purchased the NewAir AD-400 Portable room dehumidifier to use primarily in my basement. For me, it has worked Fantastic! There was so much humidity in the basement air, that for the first few days, it seemed like I was constantly emptying the unit, but after that, my musty basement smell left, and I don't have to dump water as often. I should have hooked up the unit to the drain, which was an option, but I moved it around the room to get the best placement. Definitely a good investment and a Great Product!

Overall very pleased. Quiet, low heat output, compact. The only negative thing is the size of the bucket. I understand the compact concept limits the size, but with a 40 pint per day capacity, it fills three to four times per day. This is fine on the weekends, but, as we both work, it is off during the afternoons. This is the best performing unit we have ever had.

Simply put, the dehumidifier removes water from the air in my basement, and does it well and quietly. A caution, or qualifier, however, I have used the device for only a few weeks. The real proof will be in it the length of life for the dehumidifier. Will it still be working in 6 months, a year or 5 years? My previous Whirlpool dehumidifier was very noisy and heavy, but it performed for 7 years.

At first, I was a little skeptical about this dehumidifier, but since I started using it, I've noticed a significant amount of moisture has been removed from my basement and that it is very efficient. The only complaint that I have, which is not really a major issue, is that finding a hose that will fit on the outlet to use continuous draining was a little difficult; otherwise, this product was worth the money.

I am very pleased with this product. The operation is so quiet, I didn't believe the compressor was working properly. However, the AD 400 operates 100% as advertised. I recommend this product very strongly. I have had three other dehumidifiers from various manufacturers and they are noisy.

The dehumidifier was put in service 06-10-10. I have it in the utility room adjacent to the living area in the basement and do not hear its operation it is quiet. It also has helped odor and humidity in the basement. For me what will make this a great product is if it lasts 10 yr. The last dehumidifier I used was a whirlpool and it only lasted a few years.

It came well packaged and shipped quickly. I have an 1100 sq ft basement and it does a good job of keeping the musty smell gone. Only negative comment is that it didn't come with a drainage hose, which is necessary as the tank is very small and needs to be dumped twice a day when it's warm. Does a good job, is quiet, another plus. Have only had the machine a couple months so we'll see how it does for working life.

I bought this unit because of the design and size and was not disappointed with either. It pulls a substantial amount of water and the ionizer seems to make a real difference, yet it is light enough that I can lift and move w/out straining. I do wish it had an auto on/off, but it does not - the dehumidifier does cycle off when reaching the desired humidity level, but the fan continues to blow. All-in-all, I'd say it's a B+/A-.

I have water coming into my basement during heavy rains, that leaves through the floor drain. Without a dehumidifier, I can develop moisture problems. When my very old dehumidifier quit working, I sent for the Newair AD-400 dehumidifier. I installed a drain hose leading into the drain. I leave it running and forget about it. It does a good job. I have no complaints. No noticeable change in my electric bill. Thank you Sir.

If it doesn't "die" within a year like the reviews for other dehumidifiers seemed to point out, I will be pleased. I will be even more pleased if it runs for a dozen years! (My previous one lasted 15 years!) If a person is able to drain it continually, that is best, since its reservoir is small. I use mine in the basement and have no place to have it continually drain. Even so, I go down every day to check it, and empty it every day or two. It does a wonderful job.

I've only had the unit for a few weeks but it's very quiet and works well to get the moisture out of my basement. It shipped quickly and was packaged well. My only complaint is that the bucket is small and has to be dumped frequently. The drainage hose (for continuous drain) was not included and is smaller than the regular sized hose used on other models. I'm having a bit of difficulty finding the right size to fit. Other than that it's a great price for a good machine.

I needed a dehumidifier for our partially finished basement. While our basement is not extremely damp, I felt it necessary to keep the humidity level down. From the day it was delivered and I installed it, the dehumidifier has been working perfectly. Also, I couldn't believe how quiet it runs, even on high speed. I purchase a piece of 3/8" diameter clear plastic hose and ran it from the unit to our sump pump. Everything is working great. Would definitely recommend to a friend.

The product is used in the basement, my daughter lives in the basement, she is visually impaired and all the other dehumidifiers we have tried were just too loud for her, when I turned on this dehumidifier she went wow that sounds really great it is so quiet. Due to the extreme weather we have had in New England our basement got flooded twice, the dehumidifier is doing a great job at helping get this basement dried out. All in all I would say this is a wonderful product.

For us here in the US, it would be convenient if the instructions said that the 9mm tubing specified for continuous draining is 3/8" I.D. - which is not a frequently offered size in smaller hardware stores ... they generally only have 1/4" or 1/2" I.D. available.

We had a heating pipe break. All the extra water went down between the walls into the room down stairs... we took the ceiling out, walls out, but still had to dry out the beams and the rest of the wood in the room... we use this dehumidifier for 10 days to dry out the rest of the room so we could repair it without any mold or mildew developing. Our plumber told us to get one to dry out the room... So we did and are so glad we did. This saved us many future problems we could have had with mold and mildew. It was a wonderful preventative of future problems... Thank you ...

The amount of water we have to remove every day from this device has been astronomical. Who would think there's so much water in the air? Our mold problems have decreased dramatically thanks to this dehumidifier. It's not without issues though, as it does not really dehumidify below 50% humidity as evidenced by the empty water container and it does beep annoyingly loud for far too long when it fills up to the max. 3 beeps would have been fine, but the longer beeping does ensure that somebody hears it and empties it out, so in a way it works as a feature. For the amount of money we spent on this thing, we got more than we asked for, especially compared to the other dehumidifiers on the market, which have seemingly absurd prices per performance compared to this little guy. So if someone wanted a dehumidifier, I would definitely recommend this model.

The dehumidifier helps to keep my home dry. A little over a year ago my fianc?' and I were in California to marry and the driver of our car fell asleep behind the wheel. My fianc?' was killed and I was in the hospital for 2 months, on life support for 30 days. I lived, but my body was pieced together with hardware which I am slowly having surgery now to have removed. I have extreme nerve and muscle damage, plus many other things wrong. My surgeons have said stay out of the cold and dampness, little hard when I live on a canal. I live in 24/7 mental and physical pain. Ordered your dehumidifier to help to keep the dampness out of the house. The first two days I ran it, it was full and emptied 4 times. It is a nice, great machine and I wish I had ordered it much sooner. My sister has a lung problem and she now has ordered one from you to help her breathe at night. I will do my best to sell this for you when I talk to people.

About a year ago, my old Capehart40 dehumidifier that I used in the garage got so noisy and ineffective, I junked it. After quite a few hours on the Internet, I decided on the NewAir AD-400. I set it up with a drain tube to a utility sink and started it. To this day, it runs full time, quietly and effectively removing moisture when needed which is mostly during 9 months of the year down here in tropical Florida. Congratulations on an excellent product. I also know my electric bill is less due to the much more efficient compressor.

My Wife and I are renting a house. For the last 7 months we have had mold grow all over our bedroom. We would clean it with bleach but it would pop up after a couple of days. I saw an allergy doctor and he said I should look into buying a dehumidifier. So we did. I looked everywhere but this company had the most products and feed back. It made it really easy to choose the AD-400. My room is 13' by 12' at it works great. It is very quiet and sucks up a ton of water. I have to change it probably everyday.

Currently residing in my older motorhome, and condensation is a big problem. Research suggests that a dehumidifer would help with this problem. The dehumidifer purchased (AD400) is performing excellent, removing up to 3 gallons daily on low. The living conditions are now so much more comfortable. The machine is of excellent quality, the design takes of very little room, and is very quiet in it`s operation.

We have extra moisture in our home. Anytime we took a shower or did the dishes the house would seem saturated with moisture and condensation would form on the windows. This dehumidifier is excellent. I turn it on for a few hours in the morning and run it for a couple of hours in the evening. I empty the bucket once a day and have noticed a significant decrease of moisture on all our windows! I even seem to be having less allergy symptoms. It has a sleek modern look and is so quiet! So far it has provided us a more comfotable home and it the air even feels healthier. I haven't seen the utility bill yet, so I hope it hasn't increased our electric bill too much.

My basement had flooded and there were no de-humidifiers available locally at the time I needed it. I chose the one I did because of it's light weightness and the fact it could be used as an air filter also. It has been running non-stop for almost two weeks and is performing great. I liked the design. It is easy to use and moves around on wheels with ease. I had thought the water collection container was going to be bigger though. For anyone looking for an easy to use, very quiet light weight de-humidifier, this is the one.

Purchased this dehumidifier to lower the humidity level in our house. It performs quite well - we've seen the humidity drop from the 85 percent range to the low 50 percent range, and sometimes even a bit lower, which is a great improvement. It's very light and portable, and seems to be well built. It's very quiet too. In hot humid areas, the product will still dehumidify, and do it well, but it's important to remember that all dehumidifiers which contain a compressor/fan/coils/etc. produce warm exit air. In this product, it seems to be only slightly warmer than room temperature, and so far, the advantage of the lower humidity outweighs the disadvantage of the warm exit air. But we're still evaluating it over the long term.

Satified with dehumidifier but issues with shipping and handling
I purchased this dehumidifier model in December 2009 my first one based on the reviews. It was quiet and no problems for two years then I knock it over on the carpet and had some problems. Purchased the same model in January 2012. My first one was quieter and would give it 5 stars. The second one I would give 4 stars because it is not as quiet. My only real issue is when the first one arrived it had a crack around one wheel. Reported it to Air-N-Water and they replaced it including shipping. Almost a year has passed since I purchased the second one. I was on vacation before Christmas and had it turned off. When I returned home I wiped it off and turned it on its side and discovered a crack in the bottom plastic plate. I never bothered to examine the bottom of the one I purchased in January 2012 and don't know if I have any recourse after almost a year. I would say to a purchaser examine the product after receipt of the dehumidifier because after receiving 2 dehumidifiers with cracks in the bottom the product is being mishandled by whoever is sending it or it is damaged during shipping. I work in a warehouse and see product mishandled but I see the way UPS handles merchandise and it is likely the cracks happened this way. Air-N-Water did make good on my first purchase and I give them 5 stars for that. On a side note after a year of sitting on the sidelines I plugged in #1 and tried for a few days without a hitch.

I live in Seattle in an apartment without a bathroom fan, so moisture is a big problem. The unit is working great, and my apartment is much drier, more comfortable and it feels warmer without turning up the heat. It fills up about every 36 hours.

Manual is incorrect regarding drainage pipe sizing
I bought a plastic bin that holds about 60 pints of water, placed the dehumidifier on top of it, cut a small round hole in the side of the plastic bin for the drainage hose, and connected the drainage port on the dehumidifier to the bin. The bin needs to be emptied about once a week with this setup.

We use this humidifier in a music studio and find the noise level very workable. Our studio is 40'x24' and this unit is not designed to cover a room that large but on most days it keeps up well enough. Even though this de-humidifier has a built in humidistat, we have it plugged into an external humidistat switch and it functions well. The main thing we wanted was a very quiet unit and this one fills the bill. On the downside, the bucket is quite small and needs to be checked twice a day.

The product is working well...looks good and I recommend the product to other potential buyers. Some issues - bucket capacity is a little too small so I hooked up a drain line on two units. One works great and the other one has leaked on me a few times. (Its possible gravity is working against me because the floor is not level. After a few tweaks, the jury is still out. Wish it wasn't that sensitive however,,the floor isn't THAT uneven)

This is perfect for removing moisture in a room. We are currently using this in our bedroom to assist with mold issues on the windows. It seems to be helping. Only drawback is you really need to dump the water receptacle daily so it doesn't fill up all the way. It's not easy to remove the receptacle to dump out the water, tends to splash a bit. Overall quite happy with the product.

So far I am satisfied. Very quiet unit. Drain tank is too small, company should improve the capacity in future models.

Have had the unit operating for about 4 days. So far it works as advertised; very quiet and efficient. I did read in other reviews before I purchased that users wished the water compartment was larger and I do agree with that critique. However the ideal configuration would be to have a constant drain connection. In the meantime I do not mind emptying the compartment. I do wonder how I would handle the situation if I went on vacation and was not around to empty out the water pulled in. But on the whole the unit works better than the Frigidaire unit I have in my basement.

When you turn the unit off it doesn't keep the humidistat setting. It goes back to default. Otherwise very happy.

Easy to move around with carrying handle and wheels. It's in a very humid bedroom/bathroom and does a fine job dehumidifying this 10 x 12 foot space. The catchwater tray spills a bit while removing it so I hooked up a plastic hose to the shower basin so I wouldn't have to mess with the catch water tray. When I had concerns about the unit, the support staff was fast and cordial. This was a very fine company to do business with.

We have used New Air Ad products before and the new and improved AD-400 model is performing at a level in comparison with our previous model. Great for eliminating mold and allergies for an allergy prone family. Thanks New Air!

Water, they arranged a swap at no cost to us and the xmlnsnt unit is fine. I had planned to buy a couple more of these units for other parts of the house, but I'll keep looking as I need a heavier duty product.

The dehumidifier does a wonderful job. The only objection I have is the water container which if very difficult to remove without spilling water on the floor. If it had some type of handle to remove it, it would simplify the situation. I like the fact that it is so quiet.
4.0 Star Rating: Good
My one complaint is that the holding tank is way small and can fill up overnight when the humidity is up there. However, there is a hookup for a continuous drain and it's about a foot off the floor, so the hose can make it over the shower curb okay.

Had the unit for over a month. It is a very quiet unit. I like that it has a digital readout of the humidity level in the room. The only drawback is the bucket is hard to remove/replace. Would recommend to hook up a hose for continuous drainage.

I have no complaints whatsoever. The product was priced nicely relative to other choices, delivery was prompt and the dehumidifier is effective and quiet. The true test is yet to be met - how long wil it last.

I've had the unit for about 6 weeks. I've connected a hose to the drain port instead of using the bucket. So far, works great. It's pretty quiet. I didn't realize it had an ionizer as well. Nice bonus. It's incredibly small compared to my very old unit.

I like the digital display humidistat, smooth operation, very little noise, continuous drain spout (optional), and sleek design. It is a little undersized for what I need. My old dehumidifier was larger and pulled more water out of the air, but it ate electricity and made a ton of noise. This NewAir 40 pint take a little longer compared to the beast that I had before. Overall, it seems to be a great piece of equipment. I would recommend it to anyone who needs to dehumidify 800 sq ft or less.

Purchased this dehumidifier for use in our basement that sometimes smells musty after a rain. We hooked it up to drain directly into the floor drain so there's no emptying necessary. So far everything works great!

Seems to be working well. Never shuts off, I remove the water about once a day. The water bucket is a light weight plastic; hope it lasts.

I bought the AD-400 to replace an old noisy dehumidifier that the previous owners left at our new house. It is very quiet for a dehumidifier. I also like the two speed fan, the multiple humidity level settings and the timer. The only thing I don't like so far is removing and replacing the bucket--it is hard to get lined up and put back in place. Therefore, I plan to buy tubing for continuous flow to the drain.

I have used the unit now for about a week and it seems to work well. The only issue I have is that when you power off the unit, you have to reset the humidity control number. I would like to see that the setting would stay even when it is powered off.

So far our dehumidifier has been working quietly and effeiciently. If I had a complaint it would be that the water resevoir fills-up quickly (seems smaller than the older models we used to own) and requires ME to empty almost every other day.

We use our NewAir-400 mostly in the living room, we have a large family and on a busy hot night it gets super humid its great to have the air moving. Plus it keeps my hair from getting too frizzy. I guess my only problem with it is maybe a bit more powerful our room is really big.

This is newly installed and it will take some time to assess its value in reducing mildew and humidity. I would like to review this product 1 year after installation in a beach house garage subject to extreme temperature and humidity changes throughout summer and winter seasons. The presets for humidity level and continuous drainage features hopefully will allow me to achieve suitable levels over the course of a year.

I use this dehumidifier 24/7 alternating between 2 rooms at far sides of my home. Easy to relocate as it is lightweight, has handle and wheels. And this baby can suck the moisture out of the air like a thirsty pup!! Fairly quite (about the same as a fan running on medium. Wish the bucket was a bit larger.
4.0 Star Rating: Good
new, hi-efficiency gas furnace, our humidity has been high, as high as 65% at times. This unit has been running 24-7 since we got it, and has been able to get it closer to maybe 45%, but nothing lower, as hoped, 40% is its rating. It makes a tank full of water in 24hrs, and that depends on where it is placed, right now its closer to the cold air return, and that seems to be the best location so far. It isn't overly noisy, and seems to be working well, the water container could be a bit more user friendly, it's not real easy to remove, but otherwise, seems to be doing close to it's rating. I'd say for the money, it's about as good as we had hoped for, we haven't received an electric bill since we installed it, so I can't say how well that end of it is doing, although if the energy ratings on it are accurate, it consumes about half the electricity as an Energy Star rated one. We'll see.

Works great. It's a little noisy, more so than claimed. I use it in an RV, 240sq ft. It drains to the outside of the trailer.

I am pleased with the performance of the dehumidifier as it has taken the humidity level down from over 80% to 55% (When the unit is not spilling water onto the floor). You would do well to redesign the drainage connection.
3.0 Star Rating: Average
However, it produces warm air. The dehumidifier produces air warmer than the room temperature. This is certainly not desirable in a hot weather, even in the basement.
3.0 Star Rating: Average
Just FYI...
I thought I had calculated what a 40 pint size would be, but the tank is much smaller than expected. It does the job, but I have to empty it more often than I would like. I use the unit in my basement and this was a xmlnsnt for one that finally died.
3.0 Star Rating: Average
We are satisfied that the machine is actual dehumidifying the basement air BUT despite our attempts we've been unable to get the ionizing function to come on and stay on. The manual provides no guidance in this matter. We also had to permanently glue the drain hose to the machine b/c we couldn't find one that was an exact match and has a small drip. It went into the bucket but still that defeats the purpose of having a drain hose.
3.0 Star Rating: Average
It's light and quiet, but don't expect it to really dry out a damp basement of any size. My previous one was only a 45 pint but it seemed to pull much more moisture out than this one. Also, finding 9mm plastic tubing is not easy. If Home Depot doesn't have it, I would not call it mainstream.

2) There is a mechanism that tells the Dehumidifier to turn off when the water collected reaches the full level. That mechanism is made of plastic. It has two plastic pins that allow it to seat in and move. When one of those tiny pins breaks you cannot reseat the mechanism and the dehumidifier will not turn on.

To Clarify...
Works good no problems really with the unit just thought I was getting a dehumidifier that would hold up to 40 pints in a tank before I have to empty it. Not have to empty it 4 to 5 times a day to get up to 40 pints.
3.0 Star Rating: Average
This unit draws and collects moisture very well and the quiet operation is wonderful. It's on 24/7 while trying to get to ideal level of 50%. The bucket is difficult to remove especially for anyone with arthritic hands. Also, a cover over the bucket would help prevent water from sloshing. With today's technology, it seems a company would be proud to warrant a product like this for more than 1 year instead of providing extended warranties which are a waste of money to the consumer.

Had to send the original back for a xmlnsnt, which is working fine so far. It sucks out alot of moisture (good) but the bucket is remarkably small (not good). I remain concerned about long term reliability. The electronic controls look cheaply constructed and prone to failure, and the owners manual is of little help, so I'm guardedly optimistic.

Water Returns Department was quick and easy. Just hooked up xmlnsnt unit and seems to be working well. Owner's manual is lacking and doesn't match up with actual operation of unit. Am cautiously optimistic, biggest concern is durability of electronic controls and how I will get xmlnsnt parts down the road.

We bought this dehumidifier because our basement is damp and smells damp. The dehumidifier shows 40-60 humidity, but collects very little water. Maybe needs to be emptied every couple of weeks. It is very quiet, but does it work-------------------who knows. The directions tell you NOTHING!

This unit is very quiet, and works well if you use the collection bucket. If a drain hose is connected, the unit sometimes leaks water. It appears that there is not enough pitch to the drain line as it leaves the back of the unit. I would have given this a good rating except for this issue.

The unit does use less electricity but is not powerful enough , it never shuts off. My old unit rated at 30 pints does a much better job.

Our winter's in Tennessee are dry enough and no dehumidification is needed. I will be using the dehumidifier often during the spring and summer. At that time, I will be able to evaluate your product.

I've been running the machine for about 2 weeks, I have a pretty severe moisture intrusion problem. It performs very well. However, there are a few things that I was disapointed with. The onboard hygrometer's sensor must be mounted near the water collection container. When the machine is plugged in and not running, it reads about 10% higher than it actually is. And even while it's running you can't trust it. I bought a separate hygrometer, do it if you have a severe or just bad moisture problem. Another issue is that it doesn't turn off when the set moisture level is selected. The fan continues to run until you physically turn the machine off, I found this odd and didn't impress me. It does turn off when the water collection container is full. Speaking of which, I was really surprised at the volume of the container, it's only 2 quarts. It may remove 40 pints of water in a 24 hour period, but you're going to be emptying it at least 10 times. I don't regret my purchase, but I don't think I'd buy another one. Cheers!

It is quiet compared to most, and sucks a lot of moisture out but very small bucket so you have to empty the bucket a lot. Annoying beeping everytime you take the bucket out too. I really liked it though until it died.

Until it stopped it worked well
The Machine was quiet and seemed to be efficient. Then it stopped sometime after 20 months with a compressor failure. The machine is made in China but there are no US designated repair facilities. The compressor became very hot to the touch but no cooling occurred. With no repair option the only choice is to buy a new dehumidifier but, for-sure, it will not be a NewAir product. Hopefully the next machine will be made in the USA with the option to have it fixed if the need arises. This is an awful lot of money for a throw-away household appliance.

Low noise is the best part of the machine
While I loved the compact design and low noise of the ad-400 compared to the other dehumidifiers I've owned, I couldn't believe how small the water tank was. The water tank was poorly designed, difficult to remove and when full the water splashes out because it fills up right to the top, making it difficult to carry to the sink. It was advertised as a 40 pint dehumidifier but after reading the small print it is "up to 40 pints a day" not 40 pint size tank. Even though I have used it for three days non-stop the humidity remains between 64-68, not good considering it is being used in a small sitting room. My old machine had the humidity down to 40 in a relatively short amount of time. Since I just received it, I am considering returning it.
2.0 Star Rating: OK
It seems to do the job, but the collection tank is woefully small to use without purchasing a drain tube, and the instructions aren't in sufficient detail.
2.0 Star Rating: OK
Unit is quiet, that is good. I am not sure that it removes as much water as it claims. Also the continuous drain hole is at the top of the tank so it doesn't function. I would definitely spend a few dollars more and get a better unit. "You get what you pay for".

Product stopped dehumidifying after 15 months
Purchased the AD400 in September 2011 and it worked well until January 2013 a period of 15 months. My AD400 is very clean inside and out - looks new. Took the cover out and ran it. Compressor comes on but no dehumidification. Condenser coils are not cold, but room temperature. I assume it has lost its refrigeration. According to Air-n-Water Customer Service the unit has a manufacturer's warranty of 12 months and that the refrigerant can not be recharged. Reading about others that have also had this problem I can't recommend this product due to it's lack of dependability.
