The High Efficiency Particulate Air, or HEPA, filter, was designed 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 extract 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 catch 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 capabilities, HEPA filters are deep and can limit airflow. It’s important to touch base with Sunbeam Service Experts to make sure your heating and cooling system can handle one.
Media air cleaners are much thicker 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 capture about 95 percent of particulates.
These filters work longer too, typically between three to six months.
There are several different types of electronic filtering systems you can install in your home.
An electrostatic filter uses magnetically charged material to attract. 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 ordinary filters.
An electronic air cleaner uses 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.
