What are the first points to consider when choosing an air purifier?

1. Particle size

Consider what sized particle you would like your air purifier to remove, as different machines come with different capabilities. If you're concerned about viruses, which are extremely small (<0.3 microns) then you'll want a model that includes a HEPA filter, UV lamp, and ionizer.

However, if you're concerned about allergies then you only need to filter small to medium sized microns (around 0.3) like dust mite allergens, mold spores and pollen.

2. Types

The type of purification system is key. As mentioned before there are a couple of different types of models and they can include one or more of the following:

  • HEPA filter - there are different classifications of HEPA filters. You should make sure to look for "True HEPA" filters because they are regulated by the United States Department of Energy (DOE) to be 99.99% effective at removing particles from the air.
  • UV Lights - these are used to neutralize microorganisms in the air like germs, bacteria and viruses.
  • Ionic - release negatively charged particles, which stick to contaminants in the air. This causes them to fall out of the air and land on a collection plate, which will eventually have to be wiped clean to stay effective.
  • Activated carbon filters - this is the best type of filter to use if you want to remove chemical contaminants from the air. They are also good at odor reduction.
  • Ozone - these release ozone-enriched plasma into the air reducing indoor pollutants like dust, mold, bacteria and chemicals. Ideal for areas with high pollution like bars and salons.

3. Room Size

You will want to certainly consider the size of the room you would like to purify and how much the cost of each square foot covered will amount to. Browse the different models of air purifiers based on room size below:

4. Other Costs

In addition to the cost of different models, you should also keep in mind the cost of the following:

  • Electricity bill - some models can use more electricity than others so be sure to compare how energy efficient they are.
  • Replacement filters - some models don't require any filters but others can have multiple filters that will need to be replaced regularly.

5. Aesthetics

Air purifiers come in all shapes and sizes so you can choose one that matches your existing decor perfectly. Some even come in a wood finish or heavy-duty stainless steel.

6. Warranty

When browsing the different models, you also need to make sure you pay attention to money-back guarantees and warranties. So if something goes wrong with the unit, you can get your money back or have it replace or fixed.

What should I expect my future air purifier to remove and purify?

  • People carry dirt and dust, so first and foremost, an air purifier will help purify your physical person!
  • Along with dust particles, you should find an air purifier that will help keep dust and unclean elements from your carpet, plywood or other construction materials, mattresses, blankets, and pillows, all furniture, and HVAC systems.
  • You need to have an air purifier that should rid your breathing space from household cleaning products, aerosols, insecticides, humidity and anything else that is too moist and can harbor bacteria, pets, insects and other bugs, food, and cigarette smoke.

Do I really need a top-quality air purifier?


  • If you're living in an older home or working in an older office building. This is because these older buildings tend to have more dirt and dust accumulation. Also, building regulations weren't as strict as they are today and unhealthy materials might have been used in construction.
  • If you have asthma or some other respiratory condition (such as hay fever), then you are probably more sensitive to the indoor air quality problem.
  • If your home has excessive moisture or if you have a continuous problem with leaks, then you are more likely to have mold and dust mites that need to be taken care of.
Considering all of the side effects, discomfort, and financial costs imposed by asthma, other respiratory conditions, and overall health, finding a top-of-the-line air purifier will pay off and may even be the deciding factor in answering your health problems!

Should I be considering the ozone-release factor when I choose an air purifier?

Ozone has several effects. It is harmless and useful at moderate concentrations, but harmful only at extremely high levels. Think of chlorine in your swimming pool: the chlorine functions to protect you from germs traveling through the water, but if this chlorine is available to your body at a high level, it could be fatal.

Electronic air purifiers will not produce ozone at a level higher than what is considered healthy for an outdoor setting. Negative ion and ozone air purifiers clean the air inside the same way nature does outside--emitting the world's most powerful and pure air-cleansing agents: negative ions and moderate amounts of ozone.
