This is dummy data. The water used to make ice should be as pure as the water you drink because that is exactly what you are doing when you put ice in your glass. Even if you are simply filling a cooler, did you know that adding a water filter to any ice machine will not only improve the ice quality and clarity? The performance and lifespan of each unit will be extended considerably. The machines simply become more efficient and dont have to work as hard with filtered water. It is an easy installation and changing a filter takes less than one minute. It is a small investment with considerable payback.
