The High Efficiency Particulate Air, or HEPA, filter, was created to shield scientists from radiation as they built 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 larger. 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 brand. This rating indicates how effectively a filter can pull out pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are dense and can limit airflow. It’s important to ask D & K Heating Service Experts to make sure your heating and cooling system can run with one.
Media air cleaners are denser than basic air filters. They’re often four to five times wider—or more. This barrier attaches tightly against your HVAC unit.
Because its operational surface is usually around 10 inches, media filters are able to capture 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 clearing 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 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 decrease ozone, a known lung irritant, made elsewhere in your home.
