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 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 catch 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 abilities, HEPA filters are dense and can limit airflow. It’s important to check with Teays Valley Service Experts to make sure your heating and cooling system can work with one.
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier attaches closely against your HVAC unit.
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, usually between three to six months.
There are a couple of electronic filtering systems you can use in your home.
An electrostatic filter uses magnetically charged components 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 regular 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 decrease ozone, a known lung irritant, created elsewhere in your home.
