The High Efficiency Particulate Air, or HEPA, filter, was designed to keep scientists safe from radiation as they built 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 trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the brand. This rating indicates how successfully a filter can pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are deep and can restrict airflow. It’s important to touch base with Peitz Service Experts to verify your heating and cooling system can run with one.
Media air cleaners are sturdier than regular air filters. They’re often four to five times wider—or more. This barrier attaches snugly against your HVAC system.
Because its operational surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters work longer too, commonly between three to six months.
There are a couple of electronic filtering systems you can install in your home.
An electrostatic filter uses magnetically charged material to capture. 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 ordinary filters.
An electronic air cleaner applies a high-voltage magnetic charge to trap particles.
Some can eliminate the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And minimize ozone, a known lung irritant, created elsewhere in your home.
