Unique Technology

The Air Stream Duo™ uses nebulization (cold-air diffusion), a process that breaks down essential and aroma oils into a very fine dry mist, to diffuse fragrances. This patented technology preserves the intention and integrity behind our oils, while maximizing their olfactive and therapeutic powers, without diluting in water, solvent, or using heat, to create a clean, consistent, and appealing ambient scented environment. Diffusing helps to create an emotional connection with consumers by creating lasting impressions, memories, and multi-sensory responses, all while increasing energy, inspiring brand loyalty, improving sales, masking ill odors, reducing dust, pet dander allergens, and other airborne allergens from non-living matter. Cold-air diffusers support healthy indoor air quality while providing ambience and well-being for you, your employees, and clientele.
