The High Efficiency Particulate Air, or HEPA, filter, was created to protect scientists from radiation as they worked on 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 demonstrates how successfully a filter can remove pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can limit airflow. It’s important to ask Teays Valley Service Experts Heating & Air Conditioning 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 mounts closely against your HVAC equipment.
Because its active surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters last longer too, typically 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 components 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 regular 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 reduce ozone, a known lung irritant, created elsewhere in your home.
