Product review (3 stars): It is what fits my fridge
My fridge, a Whirlpool, is built to accept this cartridge, so in my case I do not have much choice as to what to buy. The filter works well, as the water it dispenses is always free of nasty flavors (tap water in my area has an unpleasant chlorine taste) but the price is still steep. $28 for such a non-serviceable filter does seem like an awful lot, and there is no off-brand alternative. I should note that the filter is also somewhat difficult to install, though that may be an issue related to my fridge's design rather than the filter itself.
