The High Efficiency Particulate Air, or HEPA, filter, was designed to keep scientists safe from radiation as they worked on 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 bigger. 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 pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can restrict airflow. It’s important to ask A1 Chesney Service Experts Heating & Air Conditioning to make sure your heating and cooling system can handle one.
Media air cleaners are much thicker than common air filters. They’re often four to five times wider—or more. This barrier attaches snugly against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters stay fresher longer too, commonly 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 attract. 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 regular filters.
An electronic air cleaner uses a high-voltage magnetic charge to trap particles.
Some can erase 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, produced elsewhere in your home.
