It's easy to operate and requires no set up or assembly. Its sleek and compact design is ideal for small spaces. Just plug it in to a wall socket to reduce pollution and fight odors in pet areas and more. Designed to pair well with any existing HEPA air purifier, this ZERO-OZONE-verified product releases cleaner, fresher air back into the room and effectively reduces unwanted odors from pets, smoke, cooking fumes, and more.

This air sanitizer uses only a single GermGuardian UV-C light bulb (Model LB1000, ASIN: B001TLRSOA). It is recommended to replace the UV-C bulb every 6 to 8 months for optimal performance. The efficacy of any UV-C bulb diminishes over time. Adhering to the suggested replacement frequency will maximize your unit’s performance. *Tested with Staphylococcus Albus, Escherichia Coli, Aspergillus Niger, and Phi-X174.
