Product review (5 stars): Works great.  Lasts as long as advertised.
Great filters.  Sweet and tasty water.  Good value.  Arrived on time.  3rd time purchasing these types of filters on Amazon from 3 different sellers and they last as long as indicated.  We don't go through as much water as these are rated to filter so I only change them about every 8-12 months.

It doesn't say to rinse them but I do before installing.  Inside and out.  Not sure it does anything.  Just in case there is any charcoal dust.  Not sure these even use charcoal to filter.  When I remove this one I will try to remember to cut it in half and post a few pictures.
