The High Efficiency Particulate Air, or HEPA, filter, was created to protect scientists from radiation as they worked on 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 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 brand. This rating indicates how effectively a filter can clear pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can limit airflow. It’s important to ask Service Experts Heating & Air Conditioning to make sure your heating and cooling system can work with one.
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier mounts snugly against your HVAC unit.
Because its operational surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters stay fresher longer too, usually 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 substance to attract. These washable filters are 97 percent effective at removing 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 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, created elsewhere in your home.
