Product review (5 stars): fits ge smartwater filter
make sure o ring is in place before installing. I did get a quick squirt of water when installing( ge filter didn't do that). Install with a quick push and twist, and it will be only 15 or so drops of water.  Works like the ge filter. I think it took a little longer to flush out(about 30 glasses of water).  The water pressure seems to be higher with this filter.  It doesn't leak, seems to filter the water the same, and for 7 dollars less than the ge filter(with shipping), I got TWO filters. Shipping was quick, and the filter has  handy stickers to label the month of replacement.  Bravo, Water Sentinel.
