Do air filters eliminate germs?

Air purifiers remove microorganisms from the air, curbing the spread of bacteria among other harmful contaminants. HEPA filtering systems are even more effective than standard models, filtering even more bacterial particles to keep the air clean. This can help destroy viruses in-air—however, for air purifiers to be effective, harmful contaminants need to be in the air. UV lights, though, can tackle germs, bacteria, and viruses on surfaces, in air ducts, and more.
