Filters work great.  I've ordered "compatible" filters from cheaper sites that just don't work.  I mean the are "compatible" in that they fit, but they don't work.  By work I mean make the water taste, well like clean water and nothing else.

Thing that cracks me up on this offer is you can by 1 filter for $37 or if you act now and order 2, you can get them for just $77.  I'm no math major but even I know that's $3 more than buying them individually.  Now the optimist in me thinks they reduced the individual price and just forgot to adjust the "order 2 price."  The cynic in me believes it was intentionally and is deliberately misleading.  Either way, I think it needs to be fixed, thus the 4 stars.
