The High Efficiency Particulate Air, or HEPA, filter, was designed to protect 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 bigger. 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 shows how successfully a filter can clear pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are dense and can reduce airflow. It’s important to ask Comfortech Service Experts to verify your heating and cooling system can work with one.
Media air cleaners are denser than basic air filters. They’re often four to five times wider—or more. This barrier attaches tightly against your HVAC system.
Because its active surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters last longer too, usually 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 material 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 ordinary filters.
An electronic air cleaner applies a high-voltage magnetic charge to capture particles.
Some can erase 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, created elsewhere in your home.
