Lephrone

A waterless diffuser, sometimes called a cold air diffuser or liquid-less diffuser, is a premium fragrance device that disperses pure essential oils without heat, dilution, or water.

A cold air diffuser is another name for a waterless diffuser. It uses a fine nebulizing technology that turns pure oils into a micro-mist without altering their chemistry.

Yes. Waterless diffusers work by nebulizing pure essential oils into ultra-fine particles that linger in the air longer than sprays or gels. Unlike disposable air fresheners, they create an even and long-lasting fragrance

They are better if you value purity, performance, and safety. Traditional diffusers often rely on water or absorbent pads, which can dilute the fragrance, leave residue, or cause inconsistent diffusion. Lephrone waterless diffusers—also called cold air diffusers—deliver pure aroma without added moisture, making them ideal for compact environments such as luxury cars.

Depending on settings and oil choice, one refill lasts up to several weeks. Our devices use advanced cold air diffusion technology to ensure every drop of oil is efficiently utilized without waste.
