The High Efficiency Particulate Air, or HEPA, filter, was developed to keep scientists safe 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 trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. This rating demonstrates how effectively a filter can remove pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can reduce airflow. It’s important to ask R & M Climate Control Service Experts to make sure your heating and cooling system can work with one.
Media air cleaners are denser than regular air filters. They’re often four to five times wider—or more. This barrier mounts closely 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 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 material to capture. 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 minimize ozone, a known lung irritant, made elsewhere in your home.
