High Efficiency Air Filters
Why do I need an Air Filter?
Did you know the air we breathe in our homes contains dust, pollen, spores and other particles. Indoor air can be more contaminated than outdoor air!
If you have a concern about indoor air quality, you should have a high efficiency air filter or electronic air cleaner. The Aprilaire® high efficiency pleated media air filter contains a Hepa-type filter which can capture 99% of particles 5 microns or larger. Environmental Systems Associates highly recommends this product.
Advantages of a high efficiency pleated media air filter:
- Does not use electricity and thus will not produce an ozone odor.
- No moving parts.
- Filter components are not subject to mechanical failure.
- The only maintenance required is to change the filter once per year—easily done by the homeowner.
