The High Efficiency Particulate Air, or HEPA, filter, was designed to shield scientists from radiation as they worked on 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 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 well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are thick and can restrict airflow. It’s important to touch base with Air Engineers Service Experts to verify your heating and cooling system can run with one.
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier attaches tightly against your HVAC unit.
Because its functional surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters stay fresher longer too, typically 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 substance 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 catch 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, created elsewhere in your home.
