We've ordered these years and have never received a dud. All seem to work great. We write the year in a sharpy on them when installing so we know which one to replace and when. I believe stickers come with them (I'd have to ask hubby on that) but we just find it easier to use a sharpy. Will continue to purchase.

I am very pleased with my filtered water it produces. My drinking water measures in the 8 to 11 range of good drinking water range of 0 to 50 which is Ideal drinking water range.
