The NOW Ultrasonic Essential Oil Diffuser is a BPA-free aromatherapy diffuser that uses high-frequency ultrasonic vibrations to turn tap water and essential oils into a cool, ultra-fine mist. It runs up to 4 hours per fill, shuts off automatically when the water runs out, and has three rotating LED colors that can be paused or turned off. It is built for quiet, year-round use at home or in an office and is rated for 5,000+ hours of run time. Against rivals, it stands out for its no-heat, no-burn design and simple cleaning, but it lacks the larger tanks, timers and app controls common on premium diffusers.

To use it, add 120 ml (4.05 fl oz) of tap water and your essential oils. Press the power button to start diffusing and turn on three rotating LED lights. Press again to pause on one color, again to turn the lights off, and once more to shut off the unit.
It runs up to four hours, then shuts off automatically. It is quiet and easy to clean, and it can be used at home or in an office.
