The High Efficiency Particulate Air, or HEPA, filter, was designed to shield scientists from radiation as they developed 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 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 brand. This rating demonstrates how effectively a filter can pull out pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are dense and can reduce airflow. It’s important to ask Atmostemp Service Experts to verify your heating and cooling system can handle one.
Media air cleaners are denser than common air filters. They’re often four to five times wider—or more. This barrier attaches tightly against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters last longer too, usually between three to six months.
There are a few electronic filtering systems you can use in your home.
An electrostatic filter uses magnetically charged components to capture. 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 regular filters.
An electronic air cleaner applies 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 reduce ozone, a known lung irritant, created elsewhere in your home.
