The High Efficiency Particulate Air, or HEPA, filter, was developed to keep scientists safe from radiation as they developed an atomic bomb during World War II. Today these filters are often 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 catch chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating demonstrates how well a filter can pull out pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are dense and can reduce airflow. It’s important to ask Midland Air Service Experts to make sure 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 active surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters stay fresher longer too, typically between three to six months.
There are a few electronic filtering systems you can add in your home.
An electrostatic filter uses magnetically charged substance to capture. 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 involves a high-voltage magnetic charge to catch 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.
