The last filter I ordered quit working after 3 months and my indicator light to change the filter had not turned yellow or red yet on my Whirlpool fridge. My fridge is just over a year old, and even after the replacing with a second filter my icemaker was not working. After much trial and error-I was able to get the icemaker to work again. I tested the water from this newly installed filter ( after letting several gallons run through first to dislodge any sediments) and the ppm reading tested almost the same as my tap water!
I used my new Zero Water Pitcher test gauge for the comparison. I also let some ice from the fridge melt and tested it and the result was the same.
