The High Efficiency Particulate Air, or HEPA, filter, was developed to protect 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 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 trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. This rating indicates how effectively a filter can clear pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can limit airflow. It’s important to touch base with Broad Ripple Service Experts Heating & Air Conditioning to confirm your heating and cooling system can handle 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 unit.
Because its functional surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters work longer too, commonly between three to six months.
There are several different types of electronic filtering systems you can install 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 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.
