We did the whole Pur walter filter thing. They are designed to break. Period. We got tired of it and drink tons of water so we bought a Culligan under the sink water filter. Because we are plumbing disabled we called a plumber to put it in . . . which, after seeing what he did, was a stupid thing to do it was so easy but . . . hey. We replace the filter every 5-6 months (vs. every 2 months w/the Pur filter) so the price runs about the same. Worth every dime, imo. We keep a gallon jug (yeah, plastic ... can't find glass anywhere) in the fridge. We do buy bottled water by the case only for work for the kid or hubs (
he did buy a stainless bottle but it makes the water taste metallic).
