The High Efficiency Particulate Air, or HEPA, filter, was created 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 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 demonstrates how successfully a filter can pull out pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are thick and can restrict airflow. It’s important to touch base with Service Experts Heating & Air Conditioning to verify your heating and cooling system can work with one.
Media air cleaners are much thicker than regular air filters. They’re often four to five times wider—or more. This barrier mounts tightly against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters last longer too, typically between three to six months.
There are several different types of electronic filtering systems you can install in your home.
An electrostatic filter uses magnetically charged substance 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 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 reduce ozone, a known lung irritant, made elsewhere in your home.
