HEPA Filters
The High Efficiency Particulate Air, or HEPA, filter, was developed to protect scientists 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 remove 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the brand. This rating indicates how well a filter can clear pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are thick and can restrict airflow. It’s important to check with Service Experts Heating & Air Conditioning to verify your heating and cooling system can handle one.
Media Filters
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier mounts tightly 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 stay fresher longer too, commonly between three to six months.
Electrostatic Filters
There are a couple of electronic filtering systems you can use in your home.
An electrostatic filter uses magnetically charged substance to attract. 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 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, made elsewhere in your home.
