Featuring the latest atomizing technology, this diffuser converts essential oils into a microfine mist without heat or water, so you get the full, undiluted benefits of every drop. Compact enough for a cupholder or carry-on, yet powerful enough for 18 hours of use on a single charge, it brings a little serenity to the holiday season (and beyond). Simply add an essential oil bottle and enjoy simple, effortless diffusion without the worry of leaks or the hassle of cords.
