Product details:

If you see the words Fast Fill or PUR Measure on your water dispenser, stick with this filter (4396841) because 4396841 has dual flow rates of 0.50 gpm and 0.85 gpm. If you don't see those words on your dispenser, you may upgrade to the newer, improved Whirlpool 4396710 filter. The newer 4396710 filter removes more contaminants than the older 4396841 filter, including cysts and turbidity.
