Choosing IAQ Equipment
Dust mites, mold, pet dander and pollen are powerful contaminants commonly found in today’s homes. While frequent cleaning and vacuuming can go a long way toward controlling these contaminants, the best measure of defense is an air filtration system. When selecting a filtration system for your home, there are two main factors to consider:
Size of the area covered.
The most effective air-filtration options are professionally installed, whole-house systems.* Unlike portable units that cover only a single room, these systems work with your central heating and cooling system to remove and destroy pollutants throughout your entire home.
Size and types of the pollutants removed.
One highly effective solution is a HEPA (High-Efficiency Particulate Air) filtration system, which removes up to 99.97% of small particles - pollutants that standard disposable filters simply can't stop.
