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 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 demonstrates how effectively a filter can pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are deep and can restrict airflow. It’s important to check with Parker Pearce Service Experts to confirm your heating and cooling system can run with one.
Media air cleaners are much thicker than regular air filters. They’re often four to five times wider—or more. This barrier attaches snugly against your HVAC equipment.
Because its operational surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters work longer too, commonly between three to six months.
There are a few electronic filtering systems you can install in your home.
An electrostatic filter uses magnetically charged substance to attract. 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 ordinary filters.
An electronic air cleaner applies 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 reduce ozone, a known lung irritant, created elsewhere in your home.
