I love this Greenair Spa Vapor Advanced Wellness Instant Healthful Mist Therapy Diffuser. I've never had a diffuser before but I understand they can get corroded. New and improved - this Greenair
Diffuser now has an advanced ceramic disc to prevent oil corrosion and unit breakdowns; BPA Free - Now works with purified water - On/Off switches on front of unit; Beneficial aromatherapy oils are dispersed into a micro fine vapor which allows oils to remain suspended in the air for an extended time; 6 color LED lights (which can be turned on/off) create a soothing effect with their soft color changing.
The unit turns itself off when empty so you don't have to worry about burn outs or having to monitor it's use. I fill mine half full of water and then add about five drops of essential oils to the diffuser. I use Young Living Oils.
