Just saying... Getting out dissolved solids doesn't mean the water isn't still contaminated with all sorts of things. These aren't micron water filter systems. These work with cation exchange and gathering and DO NOT get everything out of the water. The label doesn't say it does either but one would assume it does based on the way it looks. Here's why you want to consider getting an RO system instead and what's the problem with Zero Water Filters. Pass it on. Becuz it kinda looks like a trick ..Hit meeeee! [email protected]
