Product review (5 stars): great filter -fast shipping
I had a subscription with a company on Amazon where they sent me a new filter every 6 months. I was paying 14.95 per filter. After just 1 year I was notified that the price would be 24.95. I canceled order and purchased the set of 3 for almost the price of 2.  I received the filters within 2 days (Prime member) and installed filters and water and ice taste great.
I recommend using this product and company. If anything I would suggest is they offer a subscription. Who knows if I can remember where I bought these in 18 months.
