HEPA Filters
The High Efficiency Particulate Air, or HEPA, filter, was designed to shield 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 bigger. This includes pollen, dirt and dust. A HEPA air cleaner with activated carbon filters can trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating indicates how well a filter can remove pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are thick and can restrict airflow. It’s important to ask Climate Control Service Experts Heating & Air Conditioning to confirm your heating and cooling system can handle one.
Media Filters
Media air cleaners are much thicker than basic air filters. They’re often four to five times wider—or more. This barrier attaches closely against your HVAC equipment.
Because its active surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters last longer too, commonly between three to six months.
Electrostatic Filters
There are several different types of electronic filtering systems you can use in your home.
An electrostatic filter uses magnetically charged components to capture. 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, produced elsewhere in your home.
