The High Efficiency Particulate Air, or HEPA, filter, was designed 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 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 catch chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. This rating shows how well a filter can clear pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are dense and can restrict airflow. It’s important to check with Service Experts Heating & Air Conditioning to verify your heating and cooling system can run with one.
Media air cleaners are denser than basic air filters. They’re often four to five times wider—or more. This barrier attaches snugly against your HVAC system.
Because its operational surface is usually around 10 inches, media filters are able to trap 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 install in your home.
An electrostatic filter uses magnetically charged substance 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 involves a high-voltage magnetic charge to catch particles.
Some can remove the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And minimize ozone, a known lung irritant, produced elsewhere in your home.
