AroMini Bluetooth gives you the most control and flexibility over scent diffusion. Created from 100% recycled aluminum, this portable scent machine stands freely, while its sleek and minimalist design harbors a state-of-art Bluetooth technology. Conserve energy and oil, by easily setting the AroMini™ run time and scent intensity by connecting it to your smartphone. The AroMini Bluetooth™ uses cold-air diffusion technology to release nanoparticles into the air that leave behind no residue. This technology preserves the integrity of our aroma and essential oils, so you can get the most olfactive and therapeutic benefits, without heat, evaporation, or diluting the oils in water or alcohol.
