Can you spell HEPA?

When researching ventilation and indoor air quality, you'll come across the HEPA filter. HEPA stands for High Efficiency Particle Air, which removes at least 99.97% of airborne particles 0.3 microns in diameter. Compare that to a human hair that is 100 microns in diameter.

HEPA filters are used when you want remove as many air quality problems as possible. HEPA filter will handle all common allergens, such as mold, animal dander, dust mites and pollen, along with some small particles from smoke and pollution. However, a HEPA filter does not filter out gasses and odor molecules.

Keep in mind that the fine tolerances that make a HEPA filter effective also make it a challenge for an HVAC system. The HEPA filter can cause back pressure problems in a system that's not designed for it.

Talk to your HVAC professional about a HEPA filter for your home. Filters can be added to existing systems, or incorporated into a new ventilation or full HVAC system in your home. Of course, freestanding HEPA air filters are available to put into a problem area in your home.
