The High Efficiency Particulate Air, or HEPA, filter, was designed to shield scientists from radiation as they developed an atomic bomb during World War II. Today these filters are regularly used in hospitals, science labs and even homes.
HEPA filters are rated to remove 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. This rating demonstrates how successfully a filter can clear pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are dense and can restrict airflow. It’s important to touch base with Service Experts Heating & Air Conditioning to confirm your heating and cooling system can run with one.
Media air cleaners are denser than common air filters. They’re often four to five times wider—or more. This barrier attaches tightly against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters stay fresher longer too, usually between three to six months.
There are a couple of electronic filtering systems you can add in your home.
An electrostatic filter uses magnetically charged components to catch particles. 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 applies a high-voltage magnetic charge to trap particles.
Some can eliminate the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And decrease ozone, a known lung irritant, created elsewhere in your home.
