Product review (5 stars): Fit my maytag fridge perfectly. No weird tastes, no odd colors.
I previously purchased Pur brand filters from Amazon at about twice the price as these, but it seems the one I bought Amazon has stopped carrying, so I decided to try the Waterdrop brand. I've had this fridge for a few years and have tried Maytag, Pur, and an off-brand filter, so I have plenty to compare it to. I cannot speak to its longevity yet, but so far it performs exactly as Pur and other more expensive filters have in the past.

If you aren't familiar with replacing your fridge filter, there are some things you should know that may seem alarming, but are completely normal. There will be air in the line after you swap your filters, whether it is the one that came pre-installed, a name brand, OEM, or other. Run the water for a few glasses before actually using it for drinking. It will spurt out and you will soon get a solid stream of water. There may be some black bits that come out (it did not this time however) which is charcoal from the filter coming out. This will also clear out if you run a few glasses of water first. You will also need to reset your 'change filter' light, --it's not that the filter is bad, it's that the fridge senses when it needs changing.. not when you've replaced it. Most fridges will list this in the manual, usually holding down a button or two for a few seconds.

So far, so good. Fit my maytag fridge perfectly. No weird tastes, no odd colors, and the air let out of the line reasonably quick. I probably ran about 4 16oz glasses of water and then I was up and running. For less than half of what I was paying for name brand and still a few dollars cheaper than the off brand ones, this filter is a definite value (currently $13). I hope this sticks around so I can continue to use this as my brand for replacements going forward.
