Product review (5 stars): PUR filter works great
I have very hard water that was ruining my Keurig coffee pot. I hated to change my refrigerator  filter  because it was over $50 each time from the dept. store. This filter did the trick. It worked on my Kenmore fridge and each time I buy one from Amazon I save about $20 over dept store prices. I have not had a problem with my coffee pot either since I only use filtered water from my refrigerator. I install it myself with no problem. I buy two at a time now so I always have a spare.
