The High Efficiency Particulate Air, or HEPA, filter, was created to keep scientists safe from radiation as they worked on 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 take out 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 indicates how well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are deep and can reduce airflow. It’s important to touch base with Sunbeam Service Experts Heating & Air Conditioning to make sure your heating and cooling system can handle 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 work longer too, usually between three to six months.
There are several different types of electronic filtering systems you can add in your home.
An electrostatic filter uses magnetically charged material 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 ordinary filters.
An electronic air cleaner uses 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 minimize ozone, a known lung irritant, made elsewhere in your home.
