Product review (3 stars): I guess they're good quality. I certainly hope so
I guess they're good quality.  I certainly hope so.  I bought the 2-pack in January, 2016 for $59.28.  Just ordered it again, August 6, 2017 for $89.99!!!
I may have to settle for unfiltered water next year because I doubt my Social Security benefit will be raised much, if at all.
