The white Rubbermaid TCell 1.0 is a sleek, modern and compact air freshener which uses advanced fuel cell technology. This means no need for batteries and a silent operation thanks to the lack of moving parts, making it completely discreet. As the system is orientation independent, it can be mounted anywhere from the ceiling, to walls and even under furniture. The fuel cell delivers a precise, timed dose of high quality fragrance to enhance any space from offices and lobbies to washrooms and even meeting rooms. There's also a large choice of fragrance refills to choose from, which last 30 to 45 days depending on the dispenser setting selected. Also available in chrome (FT577).Polypropylene
