The High Efficiency Particulate Air, or HEPA, filter, was designed 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 extract 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 catch chemicals, odors and smoke.
These filters have a MERV rating of 1721, depending on the model. This rating shows how effectively a filter can remove pollutants from the air.
Because of their high-efficiency filtration performance, HEPA filters are dense and can restrict airflow. It’s important to ask Bob Brown 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 tightly against your HVAC equipment.
Because its active surface is usually around 10 inches, media filters are able to trap about 95 percent of particulates.
These filters last longer too, commonly 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 material to attract. These washable filters are 97 percent effective at clearing 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 remove 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, created elsewhere in your home.
