Product review (4 stars): Chemical taste gone
Chemical tasting after running 4+ gallons through the new filter.  The best way to describe the taste is electrical wire burning.  The old PUR ones never had any issue.  I will update if it changes.

UPDATE: The chemical taste seems to have subsided.  The water is now drinkable.  Instead of running 4 gallons I would say double it to 8 gallons.
