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 regularly used in hospitals, science labs and even homes.
HEPA filters are rated to remove 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 capture chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the brand. This rating shows how successfully a filter can clear pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are thick and can limit airflow. It’s important to check with San Antonio Air Service Experts to make sure 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 snugly against your HVAC equipment.
Because its functional surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters stay fresher 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 catch particles. 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 ordinary filters.
An electronic air cleaner uses a high-voltage magnetic charge to capture 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.
