Does the showerhead work with hard water and/or water with a high mineral content?

Yes. The High Sierra Showerhead® will not plug up from hard water mineral deposits or from minerals (i.e. sand particles) in the water. As with any object that makes repeated contact with hard water, a coating of minerals may form at the end of the shower head. This is a cosmetic issue—your shower head will not clog from this. If this is important to you, you can prevent it by dabbing the shower head dry with your towel after showering.
