Product review (2 stars): Works, but not for long.
I'm not sure how long these filters are supposed to last, but it should be longer than a month.  I bought this filter because it was less expensive than the original LG filter.  In just over a month since I installed this filter, I can taste my water again and see little "floaties" in my water.  When I first installed the filter, the water had no taste and was clear of floaties as one would expect.  So, the filter did work when first installed, but it did not last long.

There are only three members of my household so I wouldn't say the filter was subjected to high use.  It's not like we were filling up ice chests with the icemaker in the fridge either.  We just use the water and ice dispenser for cold drinking water.

I think I'll go back to the LG filter.  It costs more, but it lasts much longer.  In the long run, the LG filter is a better value.
