The High Efficiency Particulate Air, or HEPA, filter, was created to shield scientists from radiation as they built 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 remove 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. 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 restrict airflow. It’s important to touch base with Service Experts Heating & Air Conditioning to verify your heating and cooling system can run with one.
Media air cleaners are sturdier than common air filters. They’re often four to five times wider—or more. This barrier mounts tightly against your HVAC system.
Because its active 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 several different types 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 clearing tiny particles from your home’s air. Plus, they’re also 30 times more effective than regular filters.
An electronic air cleaner involves a high-voltage magnetic charge to catch particles.
Some can eliminate 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, produced elsewhere in your home.
