Product review (5 stars): Whirlpool now owns Maytag, so these are the newer much better replacement filter for a Kenmore made by Maytag, now.
Whirlpool now owns Maytag, and that is the reason it is harder to get the Maytag filter.  It fits in just the same as the Maytag did, for my wife bought two filters from Home Depot, that did not work at all.  These allow a better water flow, than ever before, and they say, that they last longer.  I am going to buy the 3-pack next time since it is cheaper per filter price.  they say that they filter more out, too, compared to the old Maytag filter, and I believe that is because that these are of newer technology since Whirlpool bought out Maytag, and these are now suppose to be the new replacement filters by the factory.  Our fridge is a Kenmore Elite, that was made by Maytag back before Whirlpool bought Maytag, for all Kenmore products are made for them by somebody else, but by the top companies, and Sears salesperson can tell you, who made it for them, for they use several companies.
