Dehumidifier Features and Benefits

Dehumidifiers are vital for environmental control in areas where humidity can rise above 50% naturally. At humidity levels above 50%, increased water vapor present in the air can begin to allow furniture to warp, accelerate wood rot, and harbor toxic mold and fungus (which cause odors and health problems). A dehumidifier draws water in from the air and collects it into a holding tank or out through a hose connection.  A dehumidifier has a wide variety of applications, some of which might not immediately come to mind. Here are a few examples of why it's important to have a dehumidifier on hand at all times.

Protects Against Corrosion

Corrosion occurs as a material changes from one form to another through a chemical reaction. Moisture in the air often speeds up this process significantly and accelerates the reaction. Rust is a great example of this process. Rust occurs when metals begin to corrode in the presence of water vapor. Rust and other types of corrosion often shorten the lifespan of tools and other metal items causing unnecessary repairs and multiple purchases.  Dehumidifiers prevent corrosion by eliminating excess moisture in the air. 

Addresses Excess Condensation

Condensation is another problem that a dehumidifier can help eliminate. Condensation occurs when cold surfaces are surrounded by moist air. Water vapor then collects on a surface.  As a result, the surface proceeds to sweat, which causes numerous problems that includes the above mentioned corrosion.

Most people's windows are not spared either when it comes to humidity. When little droplets of water are evident on window surfaces, this is usually a sign of excess humidity in the air. This can make the general atmosphere of the room damp.  Dehumidifiers help to keep the general appearance of a room dry and clean. 

Prevents Mold and Fungus Growth

Fungi and mold are everywhere, although they often lay dormant. They become dangerous when moisture is added to the air.  Mold and fungi growth can cause serious damage to your house and health. They feed on a variety of material and can even warp your walls, windows, and furniture.  Mildew and mold can cover your bathroom and kitchen creating unsanitary conditions and blemishes on tiles and other surfaces.

Improves Health

Excess humidity has also been known to negatively affect people's health.  Humidity leads to mold growth which is potentially dangerous when airborne. They affect your allergies and have known to cause asthma. Moreover, excess humidity can affect a person's lungs and lead a variety of lung diseases. The damp heat can affect one's nasal passages too.

Another side effect of excess humidity is the spread of dust mites. Dust mites leave fecal debris that also trigger allergy and asthma attacks. Dust mites thrive in humid and damp areas, so it is important to keep your house as dry as possible.
