Operating on the process of catalytic combustion, catalytic diffusers capture and destroy odour molecules; the clever mixing of the air with convection movement destroys both odour and any airborne micro-organisms. Before scenting the air, this type of scent diffuser actually purifies it; so rather than masking odours catalytic diffusers actively cleanse the air first. This makes the catalytic diffuser unique among other home fragrance products.
Catalytic diffusers initially require a flame to light them, although this only remains lit for 2/3 minutes before being blown out. The burning of the fuel through the catalytic stone releases oxygen and fragrance into the room.
Many of the most common household odours including cooking, pets and smoke can be effectively removed in this manner.
