First of all I would like to say that I have always liked my Aquasana bottle. However, the last replacement filters ordered were not like the previous models. The current filters shown on Revain (as of June 28, 2017) also do not match what was sent to me. Filter mouths are now shorter, with just a rubber band at the neck. Because of this, I feel like the filter doesn't fit as tightly to my bottle, which sometimes causes leaks. My Aquasana bottle is not even a year old and so far I have never had a problem with the filters. See attached photos. The single band filter is what I just got and the neck dual band filter is what I used before. Note the difference in neck length. I've also included a photo of the bottle I'm currently using. Hope that helps!
