Replacement was long overdue, glad I ordered the new filter.  Updated the sticker I got a while back to remind me to replace by due date, i.e. in 6 months or earlier. Installation was easy. Pushed and pulled out the old filter, plugged in the new one. Drained several pitchers full of water cycled through the filter and the water was clear in a few minutes.
