Frequently Asked Questions

Our Technology

What is waterless cold air diffusion?

Waterless cold air diffusion uses high-pressure nebulizing technology to break pure essential oils into microscopic particles — without water, heat, or chemical carriers. This produces a dry, invisible mist that preserves the complete aromatic profile of the oil.

How is it different from ultrasonic diffusers?

Ultrasonic diffusers mix oil with water and create a wet mist, which dilutes the fragrance. Cold air diffusion produces pure, undiluted scent that fills spaces faster, lasts longer, and leaves zero residue.

Is it safe?

Completely safe. The dry mist leaves no moisture or oily residue. All oils are phthalate-free, paraben-free, and cruelty-free.
