Product review (5 stars): So far, so good
I was a bit worried as I read about people having problems with this filter leaking, but it has been working great for two days now.  Direct replacement for WMF filter.  Make sure to run lots of water through it.  I was seeing what looked like carbon powder in the water for about a 1/2 gallon of dispensed water immediately after changing.  It has cleared up and seems to be doing the job.  Has better flow rate than the Brita filter that it replaced.  I will be ordering the three pack as it seemed like a great deal.
