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 extract 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 kind. This rating indicates how effectively a filter can remove pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are deep and can reduce airflow. It’s important to touch base with Strogen's Service Experts Heating & Air Conditioning to verify your heating and cooling system can work with one.
Media air cleaners are denser than common air filters. They’re often four to five times wider—or more. This barrier mounts snugly against your HVAC unit.
Because its operational 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 a few electronic filtering systems you can add in your home.
An electrostatic filter uses magnetically charged components to catch particles. 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 uses a high-voltage magnetic charge to catch 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.
