The Fragrance Lamp diffuses fragrance and purifies the air via a method of operation known as Catalytic Combustion.

The Catalytic Lamp works when the catalyst (platinum) present on the stone part of the wick assembly is heated, which creates a catalytic reaction with the Neutral Refill or Lamp Fragrance and oxygen, which is self-sustaining while there is constant fuel and oxygen supply. The liquid in the Neutral Refill or Lamp Fragrance is drawn up the cotton wick via capillary action into the porous ceramic burner head, where the catalysis takes place, oxidising some of the liquid and releasing the balance into the air (with the fragrance, if included). The surface operating temperature of the stone can be around 350C (around half the heat of a candle flame), which destroys virus and bacteria that come into contact with it. The heated liquid rises into the air, and through convection currents is diffused quickly throughout the surrounding air. This technology is particularly effective at ensuring the liquid is emitted in ultra-fine particles which rise quickly and distribute rapidly, far smaller than droplets produced by a spray, or standard evaporation, and at a far greater rate.
