The High Efficiency Particulate Air, or HEPA, filter, was developed to keep scientists safe from radiation as they built 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 catch chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating indicates how successfully a filter can remove pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are deep and can reduce airflow. It’s important to touch base with Service Experts Heating & Air Conditioning to confirm your heating and cooling system can handle one.
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier fits closely against your HVAC equipment.
Because its active surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters work longer too, usually 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 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 uses a high-voltage magnetic charge to capture 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, produced elsewhere in your home.
