Zen Water Systems Countertop Filtration and Purification System, 6-Gallon
有问题吗？看看别人问了什么
does it or does it not filter fluoride out of the water?
How often can you expect to replace filters?
It looks like there are several different filter cartridges. How often do they need to be replaced. Is the maintenance price worth the price of admission
Why do the 5 stage filters install differently than the pictures? Black on the bottom or black on the top???
