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 frequently 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 kind. This rating demonstrates how effectively a filter can pull out pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are thick and can reduce airflow. It’s important to ask Calverley Service Experts to confirm your heating and cooling system can run with one.
Media air cleaners are sturdier than basic air filters. They’re often four to five times wider—or more. This barrier attaches tightly 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 a couple of electronic filtering systems you can add in your home.
An electrostatic filter uses magnetically charged substance 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 everyday 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 reduce ozone, a known lung irritant, created elsewhere in your home.
