The High Efficiency Particulate Air, or HEPA, filter, was developed to shield scientists from radiation as they worked on 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating shows how well a filter can remove pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are deep and can restrict airflow. It’s important to check with Service Experts Heating & Air Conditioning to make sure your heating and cooling system can handle one.
Media air cleaners are denser than basic air filters. They’re often four to five times wider—or more. This barrier fits snugly against your HVAC equipment.
Because its operational surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters stay fresher longer too, usually between three to six months.
There are several different types of electronic filtering systems you can add in your home.
An electrostatic filter uses magnetically charged substance to capture. 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 ordinary filters.
An electronic air cleaner involves a high-voltage magnetic charge to catch 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, created elsewhere in your home.
