Product review (1 stars): and seemed to work fine - 2 months later the system stopped dispensing water
Do NOT buy these products.  They clogged the system.  I installed the first one, and seemed to work fine - 2 months later the system stopped dispensing  water. I thought that it needed a new filter, installed it and the system (with the new filter on it) and it still not dispensing water. I thought that the system was broken, and it ended up being the bad quality filters that were clogging it.  Never again!!!
Piece of advise, if you still want to give them a try, please buy individual units - so in case doesnt work, you don't end up with unusable units ..
