Have used ZeroWater 12 cup pitcher for almost 2 years, the water taste is amazing, and it's reassuring to know we are drinking clean water with no contaminants.  The cost of the filters is a pricey, but I use old filters in another pitcher to pre-filter before filtering into the main pitcher in the fridge until they start dumping the contaminants. I would love to recycle them but the cost of shipping them to ZeroWater's filter recycle center is prohibitive. I swish there was a place I could drop them off locally instead of adding them to a landfill.   The pitcher spout could be improved because the water flow is too slow, but other than that I don't know if I'll ever be able to go back to non ZeroWater again.
