I thought it was so wonderful until I tried to remove and clean the filter under the sink from another water cooler. That's when I knew that this system is completely inadequate for my needs. There are no moving parts, nothing to keep crud out, nor a way (aside form dumping it into your garbage disposal ) to get any of those little white pellets back in contact with water. It would be much better just using distilled vinegar or other bottled vinegars if you want something non-toxic.
Output:
Bad review
