The Car Diffuser nebulisation technology uses the Bernoulli principle, a theorem of fluid dynamic wherein as the speed of moving fluid increases, the pressure within the fluid decreases. It atomizes and forces the breakdown of the scenting oil into ultra dry nano-particles, diffusing it into the air, by high velocity air pressure. Unlike ultrasonic diffuser, the Car Diff does not require water or heat to enjoy the scent. It releases a more potent vapor since it diffuses oil without the need of dilution, thus creating a more intense and lingering aromatic experience. It also has scent intensity controls that allow you to determine the amount of essential oil being released into the air.
