The High Efficiency Particulate Air, or HEPA, filter, was designed to protect scientists from radiation as they worked on an atomic bomb during World War II. Today these filters are frequently 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 brand. This rating demonstrates how effectively a filter can remove pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are deep and can limit airflow. It’s important to touch base with Service Experts Heating & Air Conditioning to make sure your heating and cooling system can work with one.
Media air cleaners are denser than basic air filters. They’re often four to five times wider—or more. This barrier fits closely against your HVAC equipment.
Because its functional surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters last 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 material to catch particles. These washable filters are 97 percent effective at removing tiny particles from your home’s air. Plus, they’re also 30 times more effective than everyday filters.
An electronic air cleaner applies a high-voltage magnetic charge to trap particles.
Some can remove 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, created elsewhere in your home.
