TCell air freshener refill is part of an odor control system that dispenses a consistent level of fragrance and Microtrans odor neutralizer. Inside a Rubbermaid TCell dispenser, the fresh fragrance and odor neutralizer are distributed throughout the room. The invigorating, lively and zesty orange peel fragrance features notes of grapefruit, green lemon, hints of cut stems, and light floral rose. Refill lasts approximately 60 days on the standard setting for a washroom with three to four stalls/fixtures. It can last for approximately 90 days in a small washroom with one to two stalls/fixtures. Refill contains no propellants or added VOCs.
