The High Efficiency Particulate Air, or HEPA, filter, was created to keep scientists safe from radiation as they built 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 extract 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 trap chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. 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 restrict airflow. It’s important to touch base with Aramendia Plumbing, Heating and Air 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 fits closely against your HVAC system.
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 extracting tiny particles from your home’s air. Plus, they’re also 30 times more effective than regular filters.
An electronic air cleaner involves a high-voltage magnetic charge to capture 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, made elsewhere in your home.
