3X Industrial Cartridge for Restorator or Optimum 4000

Cartridges are filled with an essential oil membrane. The oils sweat through the membrane and are dispersed into the air as a dry vapor with the help of air movers or natural air current. Cartridges work in both Restorator and Optimum 4000 machines. 3X Industrial eliminates all organic odours. Industrial cartridges are rated at 270 hours.
