Product review (5 stars): Worth it
Tried Home Depot filter for Samsung french door icemaker only.  For 5 days, the ice was still coming out varying shades of charcoal gray.  Took back, HD employee said they were junk, buy the brand name.  I did, for $50 for one.  The Samsung filter did not fit.  Took it back.  Saw these, got them faster than promised, fit like a glove, no gray ice at all, $9 a copy x4.  Absolutely buy them.  The six pack temped me, but the savings was only in the cents range, and with four that is two years of filters.
