You can control several units at a time. TWO MODES OPTIONAL: Use the smart mode to automatically adjust the settings or use the manual mode to adjust it yourself. Set the timer and adjust the ozone output once the room is unoccupied. EFFECTIVE DEODORIZATION: With a max ozone output of 10,000mg per hour this ozone generator can remove and neutralize odors from, smoke, cooking, pets, and general “musty” smells in your home. Just make sure nobody is in the room during use! EXTRA LONG TIMER: The adjustable timer allows you to produce ozone for up to 12 hours to eliminate the toughest odors and nastiest smells. Constructing the case with 304-grade stainless steel makes it anti-corrosive & easy to clean. WORD OF WARNING: All ozone generators should only be used in unoccupied spaces. Don't let people or pets enter the area until 30 minutes after ozone generation ends. Not available for sale in California; EPA Est. No.: 94720-CHN-1.
