Product review (4 stars): Works as it should, but have you done the math?
The prices on these filters go from "hey, what a great deal" to "are you kidding me?"  Home Depot prices were more expensive; I've seen them for 1.5 times what Amazon has them for... at times.  Recent prices for a 2-pack are much more than buying two individual ones.  I probably shouldn't say that, eh?  Follow the directions on installing and purging the air from the system.  It does taste better than from the tap.  I wouldn't go third-party on these, maintenance on a fridge is ridiculously expensive, not worth the few dollars saved versus what you risk.  In my opinion, of course.  It's like my HVAC air filters (buy Nordic replacement filters, Filtretes are way overprices) - replacing them every 3 months now, will save big bucks down the road,  Same for water filters.
