The High Efficiency Particulate Air, or HEPA, filter, was developed to keep scientists safe from radiation as they worked on 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 extract 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the kind. This rating indicates how well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are deep and can restrict airflow. It’s important to check with Peachtree Service Experts to confirm your heating and cooling system can run with one.
Media air cleaners are denser than regular air filters. They’re often four to five times wider—or more. This barrier fits closely against your HVAC equipment.
Because its active surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters work longer too, typically between three to six months.
There are several different types of electronic filtering systems you can use in your home.
An electrostatic filter uses magnetically charged components to attract. 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 uses a high-voltage magnetic charge to trap 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.
