The High Efficiency Particulate Air, or HEPA, filter, was designed 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 extract 99.97 to 99.99% of particles measuring 0.3 microns and bigger. 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 demonstrates how successfully a filter can remove pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are thick and can reduce airflow. It’s important to check with Church Services to verify your heating and cooling system can work with one.
Media air cleaners are denser than common air filters. They’re often four to five times wider—or more. This barrier fits 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 a few electronic filtering systems you can install in your home.
An electrostatic filter uses magnetically charged substance 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 ordinary filters.
An electronic air cleaner involves 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 decrease ozone, a known lung irritant, created elsewhere in your home.
