Product review (5 stars): No need to clean the humidifier for weeks
Most people do not realize that all water goes "bad" after only a few days.  Bacteria builds and the humidifier then sprays out bacteria into the air.  This product will keep bacteria from building and manage how often you will need to tear apart the humidifier and have to clean it.
Every night when you refill the tank, you need to rinse it out along with the standing water in the bottom of the machine.  Just rinse under water and refill the tank using this solution.  From what I understand, bacteria will not form if you continue to use this product every time you fill the tank.
I know that the smell I used to smell before using this product, which must have been caused by the bacteria is no longer there.  The air smells clean now.
