The High Efficiency Particulate Air, or HEPA, filter, was created to shield scientists from radiation as they developed 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 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 model. This rating shows how well a filter can remove pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are dense and can restrict airflow. It’s important to touch base with Rolf Griffin Service Experts Heating & Air Conditioning to verify your heating and cooling system can work with one.
Media air cleaners are much thicker than common air filters. They’re often four to five times wider—or more. This barrier fits closely against your HVAC equipment.
Because its functional surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters stay fresher longer too, usually between three to six months.
There are several different types 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 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 erase 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, made elsewhere in your home.
