The High Efficiency Particulate Air, or HEPA, filter, was created to keep scientists safe from radiation as they developed 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 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 model. This rating demonstrates how effectively a filter can clear pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are dense and can restrict airflow. It’s important to ask Midway Services to make sure your heating and cooling system can handle one.
Media air cleaners are much thicker than common air filters. They’re often four to five times wider—or more. This barrier attaches closely against your HVAC unit.
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, 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 components 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 regular filters.
An electronic air cleaner uses 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 reduce ozone, a known lung irritant, made elsewhere in your home.
