A Closer Look at HEPA Filters

There’s a good chance that your air conditioning installation contractor has recommended HEPA filters as an effective way to really improve the indoor air quality (IAQ) of your home. HEPA filters are designed to help your HVAC system get rid of smaller particles and contaminants that can pass through regular air filters. Combine them with a high-quality air purifier, and you can be assured that your home is 99% pollutant-free.

So are HEPA filters really all they’re cracked up to be? Our heating and cooling experts at Sierra Air dig deeper to find the facts behind this highly-efficient IAQ device. Here are a few facts to help you understand HEPA filters better.

A Brief History of HEPA

In the 1940s, before many heating and air conditioning repair and maintenance technicians began recommending these filters for household use, HEPA filters were already being used at nuclear facilities, where they were put into place to trap airborne particles and keep nuclear plant workers safe. In the ‘60s, their effectiveness began to be recognized in the hospital and medical industry, providing these facilities with higher IAQ levels. Today, the Environmental Protection Agency (EPA) defines home-use HEPA filters as filters that “remove more than 99 percent of all airborne pollutants 0.3 microns or larger.”

Who Benefits From HEPA Filters?

HEPA filters can be installed in almost any type of HVAC system. However, they’re most often recommended for people who suffer from severe allergies and other respiratory ailments. People with sensitive medical conditions also benefit from the higher air quality that these filters regularly provide.

Almost Perfect Filters

Sadly, there are no heating and air conditioning filters that can boast a 100% performance rate when getting rid of contaminants. However, HEPA filters are by far the most efficient option, boasting a rating of 99% or higher. There are still some extremely small viruses and bacteria that can pass through them, but these are rare and essentially negligible.
