Product review (3 stars): PUR Water Filter
We recently purchased a Sears refrigerator with the PUR water filter. To our surprise, the filter indicater, above the water dispenser, began running low within just several weeks of our purchase. So, we ordered another one online thinking our water consumption was a little high due to peak baseball season and summer time. Still, replace it in just 6 weeks? We were perplexed, but ordered a new one any way. The new one indicated a need of replacement just about the previous, original one. When I spoke with a Sears Tech, I was informed that the water filter company mark their computer indicater to replace per an originally programmed and measured number of consumed gallons it holds. That does not mean it is no longer effective when you consume more than the anticipated number of water gallons.  The tech told me to ignore the indicator as it could be a gimmick for the company to make more money. I was further advised to replace it in 6 months as it lasts that long without worries. And so we did, and did not notice any water taste change. You decide what you think!
