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 often 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating indicates how effectively a filter can pull out pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are thick and can reduce airflow. It’s important to touch base with Komfort Air to confirm 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 closely against your HVAC equipment.
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, 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 capture. These washable filters are 97 percent effective at removing 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 catch 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, produced elsewhere in your home.
