The High Efficiency Particulate Air, or HEPA, filter, was designed to keep scientists safe from radiation as they developed 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 bigger. 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 brand. This rating demonstrates 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 Bryant Heating & Cooling Service Experts to confirm 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 equipment.
Because its functional surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters stay fresher longer too, typically 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 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 capture 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.
