Air fresheners neutralise odours that a carbon filter can't catch, for example when you open the tent, trim, dry or simply want a fresh-smelling room. This collection contains the SmellCrusher range: Gel in Breeze, Bubblegum, Fabric Fresh, Lemon and Orange, the 40 Day Gel, SmellCrusher Absorb, Fabric Refresher, Perfume and a Car Freshener. Gels work passively and continuously; place an open container near the source and replace it when it dries out. Sprays and the fabric refresher act instantly on clothes, textiles and small spaces. Combine them with a filter from carbon filters, see the SmellCrusher brand page and read about odour control in the grow room.
