The High Efficiency Particulate Air, or HEPA, filter, was developed to shield scientists 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 take out 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 trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the brand. This rating demonstrates how successfully a filter can pull out pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can limit airflow. It’s important to check with Abbey Air Service Experts Heating & Air Conditioning to verify your heating and cooling system can handle one.
Media air cleaners are sturdier than common air filters. They’re often four to five times wider—or more. This barrier mounts tightly against your HVAC system.
Because its operational surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters work longer too, typically 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 components to attract. These washable filters are 97 percent effective at extracting 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 catch 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, made elsewhere in your home.
