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 take out 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 trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating demonstrates how successfully a filter can clear pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are deep and can restrict airflow. It’s important to check with Service Experts Heating & Air Conditioning to confirm your heating and cooling system can handle one.
Media air cleaners are sturdier than regular air filters. They’re often four to five times wider—or more. This barrier attaches tightly against your HVAC equipment.
Because its functional surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters last longer too, typically between three to six months.
There are a couple of 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 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 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.
