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 brand. This rating demonstrates how successfully a filter can clear pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are thick and can reduce airflow. It’s important to check with Strand Brothers Service Experts to confirm your heating and cooling system can work with one.
Media air cleaners are sturdier than common air filters. They’re often four to five times wider—or more. This barrier mounts snugly 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, commonly 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 attract. 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 everyday filters.
An electronic air cleaner involves a high-voltage magnetic charge to capture particles.
Some can remove 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, produced elsewhere in your home.
