The High Efficiency Particulate Air, or HEPA, filter, was created to shield scientists 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 remove 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 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 clear pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are dense and can limit airflow. It’s important to ask Calverley Service Experts to verify your heating and cooling system can work with one.
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier mounts snugly against your HVAC equipment.
Because its active surface is usually around 10 inches, media filters are able to catch about 95 percent of particulates.
These filters work longer too, usually between three to six months.
There are several different types of electronic filtering systems you can install in your home.
An electrostatic filter uses magnetically charged components to catch particles. 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 ordinary filters.
An electronic air cleaner involves a high-voltage magnetic charge to trap 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, made elsewhere in your home.
