The High Efficiency Particulate Air, or HEPA, filter, was created to keep scientists safe from radiation as they built 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 model. This rating indicates how effectively 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 touch base with Eveready 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 fits snugly against your HVAC equipment.
Because its functional surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters last longer too, commonly between three to six months.
There are a couple 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 regular filters.
An electronic air cleaner applies a high-voltage magnetic charge to trap particles.
Some can eliminate 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, produced elsewhere in your home.
