We'll just come out and say it: some A/C filters and furnace filters actually can destroy bacteria ... as long as they have the correct means to do so.
Bacteria is in all things, and on all surfaces — we literally can't get rid of it. For that reason, there's no use trying to hide from it; we can only reduce our exposure to it. In fact, even products such as antibacterial soap (which uses an active ingredient called 'triclosan' to fight bacteria), was found by the FDA to be no more effective than regular soap and water.
...So how is it that an air filter can destroy bacteria upon contact?
Well, we can only speak for Purity brand products and air filters, but our furnace and air conditioning filters have a special adhesive added onto them that is highly effective in trapping and destroying the bacteria in the air. After trapping the bacteria from the air, our filters hold the small particles (which are micron-sized), and a special agent that is added onto the filter destroys it. The special agent is an antimicrobial, which is a known fighter of bacteria, viruses, fungi, and protozoa. That means that our filters can not only trap and destroy all of that floating in the air, but they can defend against bacterial spores, mold, mildew, and more — as long as the filter comes in contact with them.
In addition to destroying those harmful spores and bacterium, it can also inhibit the growth and multiplication of bacteria, mold spores, mildew, and algae. And stopping the growth of harmful bacteria is key to living a healthier indoor life. It's the key to breathing easier.
