The V-Air Solid Air Freshener Refill Cool Mint, non aerosol refill cartridge, is uniquely constructed from ceramic, infused with high quality perfumes, then complemented by an integrated internal fragrance core. These combine and diffuse powerful key fragrance notes that are subtly different. The diffusion rate of fragrance moving through the ceramic capsule is much different to the fragrance evaporating from the surface of the fragrance core. The Cool Mint fragrance begins with cedar and pine, evolving into a cooling herbal aroma. This subtly transforms into a blend of energising wild mint and eucalyptus and touch of lemon spearmint.
