The invention concerns a process and a device for the deodorizing, and/or fragrancing of an environment. In the invention, a device is placed in that environment, which is a container (

) comprising perfumed particles (
2
) which emit their perfume outside the container.
A perfume composition providing differentiated odour depending on the assessment conditions is provided. The perfume composition includes a) less than 20% by weight of perfumery ingredients having an equilibrium headspace concentration (HS) between 151 and 900 microgram/l at 25° C., b) at least 35% by weight of perfumery ingredients having a HS higher than 900 microgram/l at 25° C. and b) 25% by weight of perfumery ingredients having a HS lower than or equal to 150 microgram/l at 25° C. The perfume composition reduces consumer perfume habituation to said perfume product.
