Product review (5 stars): Good filter for household use
These are great for removing particles from water.  They will also remove most chlorine and some bacteria.  I use them to pre-filter water for my built-in plumbed in coffee makers.  They keep the check valves working and I've not had a clogged valve since they were installed.  Sometimes cheaper to buy the entire GE Kit rather than the filter as they kits are sometimes on sale for less than the cost of the filter alone.
