The High Efficiency Particulate Air, or HEPA, filter, was developed to protect scientists 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 kind. This rating demonstrates how effectively a filter can clear pollutants from the air.
Because of their high-efficiency filtration abilities, HEPA filters are dense and can limit airflow. It’s important to ask Abbey Air Service Experts to confirm your heating and cooling system can handle one.
Media air cleaners are sturdier than common air filters. They’re often four to five times wider—or more. This barrier attaches snugly against your HVAC system.
Because its functional surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters work longer too, typically 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 substance to attract. 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 trap particles.
Some can remove 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.
