The High Efficiency Particulate Air, or HEPA, filter, was created to keep scientists safe from radiation as they developed an atomic bomb during World War II. Today these filters are frequently used in hospitals, science labs and even homes.
HEPA filters are rated to take out 99.97 to 99.99% of particles measuring 0.3 microns and larger. This includes pollen, dirt and dust. A HEPA air cleaner with activated carbon filters can catch chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating shows how well a filter can clear pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are deep and can reduce airflow. It’s important to touch base with Service Experts Heating & Air Conditioning to verify your heating and cooling system can handle one.
Media air cleaners are much thicker than regular air filters. They’re often four to five times wider—or more. This barrier fits closely against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters work longer too, commonly between three to six months.
There are a couple of electronic filtering systems you can use in your home.
An electrostatic filter uses magnetically charged substance to attract. These washable filters are 97 percent effective at extracting tiny particles from your home’s air. Plus, they’re also 30 times more effective than ordinary filters.
An electronic air cleaner uses a high-voltage magnetic charge to catch particles.
Some can remove the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And minimize ozone, a known lung irritant, produced elsewhere in your home.
