The High Efficiency Particulate Air, or HEPA, filter, was created to keep scientists safe from radiation as they developed 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 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. This rating demonstrates how successfully a filter can clear pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are deep and can restrict airflow. It’s important to touch base with Epperson Service Experts to make sure your heating and cooling system can run 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 tightly against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters work longer too, typically 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 components to attract. 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 everyday filters.
An electronic air cleaner uses 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 minimize ozone, a known lung irritant, created elsewhere in your home.
