The High Efficiency Particulate Air, or HEPA, filter, was developed to protect scientists from radiation as they worked on 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 remove 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the brand. This rating shows how well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are dense and can restrict airflow. It’s important to ask Service Experts Heating & Air Conditioning to verify your heating and cooling system can handle one.
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier mounts snugly against your HVAC unit.
Because its active 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 a couple 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 everyday filters.
An electronic air cleaner applies 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 decrease ozone, a known lung irritant, created elsewhere in your home.
