Review Content Smells Amazing I own all three of these scents for my 3 in 1 home Purifying System. They smell great and last a long time. Small but efficient Just wish that the scents were in bigger bottles, because they run out quite quickly. I bought one for the bedroom and it does make a difference in sleeping..... Wish one covered more square footage, otherwise very easy to use, no filters. Just clean every two days and add fresh water. AWESOME I use it in my Hand and Foot Spa, keeps the air moist, dust-free and fragrant. This is a great product. I use this product in my office & in my bedroom. Will probably order a couple more for other rooms-cleans air. Great!!!
