HEPA Filters
The High Efficiency Particulate Air, or HEPA, filter, was designed to keep scientists safe from radiation as they built 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 model. This rating shows how well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are dense 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 common air filters. They’re often four to five times wider—or more. This barrier attaches closely against your HVAC equipment.
Because its functional 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 add in your home.
An electrostatic filter uses magnetically charged components to capture. 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 regular filters.
An electronic air cleaner involves a high-voltage magnetic charge to capture particles.
Some can erase 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, produced elsewhere in your home.
