The High Efficiency Particulate Air, or HEPA, filter, was created 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 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 indicates how effectively a filter can pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can reduce airflow. It’s important to check with Service Experts Heating & Air Conditioning to confirm your heating and cooling system can run with one.
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 operational surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters last longer too, commonly 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 material 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 ordinary filters.
An electronic air cleaner applies a high-voltage magnetic charge to capture particles.
Some can eliminate the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And reduce ozone, a known lung irritant, made elsewhere in your home.
