The High Efficiency Particulate Air, or HEPA, filter, was developed to shield scientists from radiation as they built 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 model. This rating demonstrates how effectively a filter can remove pollutants from the air.
Because of their high-efficiency filtration capabilities, HEPA filters are thick and can limit airflow. It’s important to ask Service Experts Heating & Air Conditioning to make sure your heating and cooling system can handle one.
Media air cleaners are denser than regular air filters. They’re often four to five times wider—or more. This barrier mounts tightly against your HVAC unit.
Because its operational surface is usually around 10 inches, media filters are able to capture about 95 percent of particulates.
These filters stay fresher longer too, typically between three to six months.
There are several different types of electronic filtering systems you can add in your home.
An electrostatic filter uses magnetically charged components to catch particles. 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 everyday filters.
An electronic air cleaner uses a high-voltage magnetic charge to catch particles.
Some can erase the majority of indoor air pollutants—particles, germs, bacteria, chemical odors and vapors—by up to 99.9 percent. And minimize ozone, a known lung irritant, created elsewhere in your home.
