Product review (5 stars): EveryDrop filter good replacement for discontinued blue filters
Edit 6/4/18: Just installed my second one of these filters with similar results as they first.  Fill rate is very consistent with the first filter and the old blue ones. No noticeable odor or taste issues. I will continue ordering these every 6 months until i have an issue.

Original review: I finally gave up trying to find the old blue filters and ordered one of these EveryDrop filters.  I had concerns about the taste and fill rate issues that other people mentioned in their reviews.  I'm happy to report that I have had no issues and the filter works just like the old blue one or better.  Here is some additional info for others who might have the same concerns.  My old filter was the fast fill type.  On the label it was rated at 0.5 gallons per minute (GPM).  The new filter does not say fast fill but is also rated at 0.5 GPM.  To test how they compared, I filled a 2 liter bottle that I had available before I removed the old filter.  The 2 times I filled it took 1:04 and 1.03 respectively.  I installed the new filter and timed it from the very first button push.  The water looked clear from the very beginning and had no smell that I could notice.  The first fill took 1:24 and there was some sputtering as air was purged out of the system.  But by the end of filling the 2 liter the first time I could tell the flow was better.  The second fill had a little bit of sputtering and it took 1:11.  After that, the times were all between 1:03 and 1:05 with no air.  The old filters had air pockets much longer than this one did.  The packaging recommends flushing 4 to 5 gallons through the filter before use so I filled the 2 liter 8 times which is just over 4 gallons.  I then left it alone for about 30 minutes to make sure the filter was filled and saturated.  I filled the bottle 2 more times to flush any remaining stuff out.  My first glass of water was clear and tasted good.  I can now recommend these filters to replace the old blue ones.  I highly recommend doing the full flush process before using the water to drink or for ice.
