The High Efficiency Particulate Air, or HEPA, filter, was developed to protect scientists from radiation as they developed 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 extract 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 model. This rating indicates how well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are thick and can reduce airflow. It’s important to check with TML Service Experts to make sure your heating and cooling system can run with one.
Media air cleaners are much thicker than basic air filters. They’re often four to five times wider—or more. This barrier fits snugly against your HVAC equipment.
Because its operational surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters stay fresher longer too, usually 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 capture. 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 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 minimize ozone, a known lung irritant, made elsewhere in your home.
