Can I use my filter with hard water?
Edited

All Santevia products can be used with hard water. The efficacy of the filter will not be impacted.

It's important to note that the "hardness" of water is not a measure of its overall quality or safety for consumption. The "hardness" merely refers to its dissolved mineral content and the effects this can have on plumbing. Hard water has more minerals such as calcium and magnesium due to water passing through rocks like limestone. These minerals are essential for your health and give water a smooth, fresh taste. Santevia adds essential minerals like calcium, magnesium and potassium to water.
