Product review (5 stars): May last longer than 6 months! Depending on air and fridge quality.
We had the original filters that came with the fridge when it was delivered in July 2013. They were not the starter filters, but the regular ones like this. We didn't pay much attention, but did look at the little indicator every so often opening up the fridge for something. The indicator always showed that we were good to go, so as time went on, now two years later, the indicator finally showed that it was nearing time to change the filters. Actually, we could have gone another several more months on the old filters before the indicator reached the end; making it 2.5 years max. Anyway, it's been 2 years and two months on the original filters with the indicator almost to the end when I changed them out for these last night. I bought several packages, so I figure I will have a good 6-7 year supply for $60!!
