All Aura House scent diffusers utilize Cold Air Diffusion – a technology that disperses fragrance oils by turning them into a fine mist of nano-particles. This eliminates the need for water or heat, which ensures that the scents are diffused in their original form and preserves their integrity. This method of diffusion is more efficient and powerful than traditional methods, as it allows for a more consistent scent that lasts longer. Cold air diffusion is the most low-maintenance, clean way of scenting your home or workplace because it creates no steam, vapor, or mold.
