What Are HEPA Filters?

Air filtration in homes is no longer a luxury; it’s becoming a necessity to allow for fresh and safe indoor air for homes that have heavy air sealing to preserve their energy efficiency. Although you can open up doors and windows to allow in fresh air, there are very few times during the year when this is feasible for any length of time, and it causes a home to lose energy. With filters installed in your house’s HVAC system, you can enjoy increased indoor air quality without needing to overwork your heater or air conditioner and incur higher bills.

There is a variety of ways to have air filtration in Atlanta, GA. One of the most popular and inexpensive is through the installation of HEPA filters. You may have heard of these filters but didn’t know exactly what they are or how they work. We’ll go into details about these powerful filters. If you are interested in having HEPA filters put into your home, or some other method of air filtration, call the indoor air quality specialists at Premier Indoor Comfort Systems today.

HEPA filters

The acronym HEPA stands for “high-efficiency particulate air.” It is a standard for air filters the U.S. Department of Energy sets. To qualify as a HEPA filter, an individual filter must remove 99.97% of particles down to 0.3 microns in size (also known as Most Penetrating Particle size, or MPPS).

A HEPA filter consists of a mat of fibers in a random arrangement, usually made of fiberglass strands between 0.5 and 2.0 micrometers. The space between the fibers is actually larger than 0.3 microns, but the filters do not work strictly through stopping particles like a strainer. Instead, the fibers attract particle to them through interception and diffusion. Through these processes, they also affect many particles smaller than 0.3 microns, making them effective for filtering out almost all physical particles from the air that pass through the filters.

However, HEPA filters are ineffective against gases and odor molecules, which are not affected by either interception or diffusion. For homes that need to combat gases such as cigarette smoke, household chemicals, and odors, an electronic air purifier is often needed as an adjunct to a HEPA filter.
