Bests & Worsts Reviews from Amazon

Overall we have found this to be a great water filter. But we have had our water tested by a professional, both at the tap, and at the filtered tap on the refrigerator. Both waters tested the same for chlorine content, however, the particle contaminants were greatly reduced by the filter on the refrigerator. Something to note on your water filter. The light is merely a timed indicator of when they want you to replace the filter. Think of it as a "countdown timer" that starts as soon as you reset it. It is in no way measuring the amount of water you are consuming... Personally, I used to change out the filter every 6 months when the indicator light came on, but we rarely use the water/ice now, so I haven't changed it (or reset it) in over a year although I probably will soon. I actually cut the first one in half to see how "contaminated" the filter was and to my surprise, it looked like a brand new filter... The life of a filter depends on a couple of things. 1. The amount of contaminants in your water (well water is typically the worst) 2. The amount of water that passes through the filter If you have low contaminants and/or use very little filtered water, your filter will last much longer than 6 months. If you pay attention to the amount of water flow and the size of your ice cubes, you can more accurately determine the proper time to replace the filter. I have county water and we also have installed a "whole house" water filtration system, so I can probably get closer to 2 years out of a filter. Obviously, not everyone has these installed though, just use common sense on when to replace your filter and you'll be fine. P.S. Why is it more expensive per unit to buy the 3-pack than it is to buy the 2-pack? Am I the only one that found this odd?
