The High Efficiency Particulate Air, or HEPA, filter, was created to protect scientists from radiation as they developed an atomic bomb during World War II. Today these filters are regularly used in hospitals, science labs and even homes.
HEPA filters are rated to remove 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 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 pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are deep and can limit airflow. It’s important to check with Strand Brothers Service Experts to confirm your heating and cooling system can handle one.
Media air cleaners are much thicker than common 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 capture 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 install in your home.
An electrostatic filter uses magnetically charged components 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 involves a high-voltage magnetic charge to catch particles.
Some can erase 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, made elsewhere in your home.
