Product review (5 stars): I listened to bad reviews for no reason
UPDATED WITH CUT APART PICTURES OF EVERY DROP FILTER- still just charcoal in a sock ;)
There are many recent poor reviews of this product since the changes made to the filter packaging in winter 2015.  Being a diligent Amazoner I listened and ordered the "old" 4396810 blue filter from another source that appeared to have back stock.  Well they sent me the new filters! So I gave it a try.

The packaging mentions it is still a PUR licensed filter.  I popped it in, ran out a gallon.  The water was clear and taste like nothing-just how I like my water.

I will update as appropriate for longevity.  I found the blue filters to be good for 3-4 months in the summer and 4-5 months in winter ( we drink mush more in the summer)

I also opened up the blue filter to see what is so special that people yearned for, it's just a chunk of charcoal with a sock on it.  I'll open up the new white filter when it is spent.
