The High Efficiency Particulate Air, or HEPA, filter, was developed to shield scientists from radiation as they built 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 remove 99.97 to 99.99% of particles measuring 0.3 microns and larger. 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 shows how well a filter can remove pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are dense and can limit airflow. It’s important to check with Coastal Service Experts to confirm your heating and cooling system can handle one.
Media air cleaners are much thicker than regular air filters. They’re often four to five times wider—or more. This barrier mounts closely 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, 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 material 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 regular filters.
An electronic air cleaner uses 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 decrease ozone, a known lung irritant, created elsewhere in your home.
