Product review (3 stars): Not sure if this is for my cool air filter....
Wanted to purchase to ensure quality of water/air coming out of unit for my baby. I only used one capful for the VICKS cool air humidifier. Read somewhere that this product is more for the wick units (the ones that use that honeycomb filter looking thing). It left a white powder residue so I will not use again with baby; not sure if it is toxic. I will use that little ball thing instead and clean unit more often.
