Product review (1 stars): Doesn't seem like it's worth the cost to buy brand-name filters if ...
Lasted about a month.  These filters seem to have a progressively shorter lifespan--I replaced the filter in January, then again at the end of April, and now it needs to be replaced again as the water trickles so slowly from the dispenser that it takes about a full minute to fill up a glass of water.  Doesn't seem like it's worth the cost to buy brand-name filters if they only last a month.
