Product review (4 stars): Great scientific reason given by manufacturer
water has a stale taste , no other filter of the 5 different brands had that stale taste.
Great scientific reason given by manufacturer, but unfortunetly, it still is stale tasting water

10-5-2016 > UPDATE
The manufacturer sent a replacement filter. I ran it for 2 weeks and NO STALE taste from jump start.
Water tastes great and definitely a great deal and great company to deal with.
I will surely buy again from this company.
