Product review (5 stars): A very nice quality filter replacement.
Seems to be working fine. No visible grains in water after one 8oz flush. Are these OEM filters? Hard to say, but they fit and operate like the originals.
Straight-forward install, but, requires a hefty pull to remove and serious pushing to get back in.
For LG refrigerators, here is some advice. (1) be SURE that the current filter is pulled/pushed FULLY downward before you start tugging on it. DO NOT ROTATE clockwise or counterclockwise. Downward only. It won't release easily. (2) push the new filter in fully. DO NOT ROTATE. The filter will only allow you to move it upwards into place when it is fully inserted, and it requires some serious pushing into the fitting..

Most importantly, Ill be ordering the 3-pack now that Im confident about these working as specified.
