GermGuardian AC9200WCA Air Filtration System

The air filtration system of GermGuardian AC9200WCA consists of:

- activated carbon air filter traps smells, odors, and VOCs.

- optional UV-C light in combination with Titanium Dioxide (TiO2) and air ionizer kills airborne germs, bacteria, and viruses and removes very small airborne particles (smoke, for example) from the air.

Since UV-C light/ionizer creates some ozone (amounts are much below required safety levels), UV-C light/ionizer can be turned off - personally, if You want to remove tiny tobacco particles (smoke) one should really have the UV-C light/ionizer turned ON.

Note: this goes for all similar units, not just for GermGuardian AC9200WCA air purifier.
