Dehumidifiers
Back
One of the most important factors in improving indoor air quality is by controlling humidity. Indoor Relative Humidity should be kept between 40% to 60% for optimum air quality. High humidity breeds mold, mildew and dust mites.
How Does Relative Humidity Affect Us?
Other than health issues related to respiration, humidity affects our ability to cool down. We cool down by releasing water through our pores in the form of sweat which evaporates carrying away excess body heat.
The evaporation rate depends on the humidity of the surrounding air. The more humid the air, the slower the evaporation process. When we are in humid air, the sweat evaporates more slowly then it does in dry air. Thus less water molecules are leaving our body, carrying away heat, which means that we are left with heat. This makes us hotter and we are also wetter.
How Do You Know If You Need a Dehumidifier?
A dehumidifier is used to remove excess moisture from the air. Some of the most common indications that you may need a dehumidifier are:
- Wet stains on walls and ceilings
- Stuffy feeling in a room
- Rotting wood
- Condensation on windows
- Musty smells
- Allergies (if the air in your home is too moist, it will encourage the growth of bacteria and mold, common allergies.)
