I recently purchased a Spamist Ultrasonic Diffuser, and I love it! I use it every night before I retire, and the soothing aromatherapy vapors relax me and help me fall asleep. This particular unit was only $19.99, so I thought it might not work very well, but so far, I have been very pleased with its performance. The auto-shutoff feature kicks in after about three hours, but I am always asleep by then. You can set this diffuser to display a rotating rainbow of colors, one color only, or you can shut off the light. It’s easy to fill and easy to clean.
Here’s the description of the Spamist unit which I purchased:
“Create the ultimate spa experience—anytime, anywhere.
SpaMist instantly converts normal tap water to a healthy streaming mist with the latest ultrasonic technology.
The sleek modern design fits any decor and is simple to use. Just add less than one cup of water and a few drops of your favorite essential oil. Enjoy more than 3 hours of continuous aromatherapy.
For a pleasant lighting effect, either select the rotating rainbow spectrum or one of the 6 soothing LED colors. Lights may also be completely turned off during the diffusing process. SpaMist completely powers down when the level of water falls below the minimum fill line.
Cleaning is easy, just wipe wipe the inside out with a soft cloth before duplicating the above process.
Unit Weight = .60 lbs
Unit Dimensions = 4.5″L x 4.5″W x 7.5″H
Case pack Weight = 7 lbs
Case pack Dimensions = 15″L x 10″W x 8.5″H”
Though I usually use lavender essential oil in my diffuser, I also love Serenity aromatherapy oil by doTERRA. If you have trouble winding down from long, stressful days, or you simply want to enjoy the calming effects of essential oils, I would HIGHLY recommend purchasing a diffuser unit and placing it near your bed.
