Aroma-Ace™ comes with a five year warranty and is manufactured in the USA – Change essential oils in seconds with the innovative quick change system. Simply twist a new bottle of essential oil into the atomizer at any time without mixing or spilling. Advanced, built-in, easy-to-use timers provide exceptional operational control and convenience. State-of-the-art Cold Diffusion technology preserves the natural essence and complete therapeutic benefits of essential oils by effectively transforming them into a micro fine vapor without the use of heat or water. These micro particles permeate the air and remain suspended for hours, fully intact, with all of their NATURAL defenses against airborne viruses, bacteria, mold, pests, and odors. Other common uses are for respiratory therapy, mood enhancement, relaxation, well being, air purification and more. The new 12V Aroma-Ace™ eliminates any power restrictions that a fixed voltage system creates in a global market.
