The GermGuardian® UV-C Room Air Sanitizer uses a replaceable 9-watt UV-C bulb to kill over 99% of targeted airborne germs, and a filter to destroy odors and allergens like dust mites and mold spores.
The 9-watt UV-C bulb and filter should be replaced every 6-8 months depending on use.
Both the UV-C bulb and filter are sold together as a single replacement pack.
This is a GENUINE GermGuardian® Bulb. It is important to only use genuine Guardian Technologies™ replacement parts to maintain product performance and warranty. All parts that are not genuine will void the warranty.
