I used to have a recurring order set up on Amazon to have these shipped to me every 6 months, however the last handful of them have only lasted 4 to 10 weeks! (with only 2 people in the house and supplementing our water consumption with a Brita pitcher and bottled water) The water on my refrigerator door would cease to work, I would turn the water line off, pop the filter out and then put it back in, and then turn the water line back on and it would sometimes fix the problem for about 2-3 drinking glasses and then stop working again. I was going crazy diagnosing the water line, water pressure, the water shut off valve, solenoid in the back of the fridge. With absolutely no help whatsoever from the Whirlpool/ KitchenAid company I figured out the problem on my own... on a suspicion I bought a new filter at BestBuy and it fixed my problem. So I called Amazon (where I purchased the water filter from, but since it was sold on Amazon by ‘EveryDropCounts by Whirlpool’ Amazon told me that I would need to contact Whirlpool for assistance. Whirlpool accused me of buying a counterfeit water filter and accused Amazon of selling me a counterfeit product, and told me that there was nothing that could be done. I put up with 2 or 3 filters only lasting about 2 months before suddenly stop working, but when my last one barely lasted a month before stopping and causing me to put 2 hours into diagnosing the problem - I had to call Whirlpool and see what they could do. BUYER BEWARE - NEVER PURCHASE A WHIRLPOOL WATER FILTER FROM WHIRLPOOL OR ‘EveryDropCounts by Whirlpool on AMAZON. ONLY BUY FROM BEST BUY - their filters work and actually last about 6 months, and if for some reason they don’t - they will take care of you and not accuse and harass you.
