The High Efficiency Particulate Air, or HEPA, filter, was developed to shield scientists from radiation as they worked on 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 extract 99.97 to 99.99% of particles measuring 0.3 microns and greater. This includes pollen, dirt and dust. A HEPA air cleaner with activated carbon filters can trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. This rating indicates how successfully a filter can remove pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can restrict airflow. It’s important to check with Mountainwest Service Experts to make sure your heating and cooling system can run with one.
Media air cleaners are much thicker than common air filters. They’re often four to five times wider—or more. This barrier mounts tightly against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to trap 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 install in your home.
An electrostatic filter uses magnetically charged components 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 regular filters.
An electronic air cleaner applies a high-voltage magnetic charge to trap particles.
Some can remove the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And reduce ozone, a known lung irritant, made elsewhere in your home.
