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.
