Yes, by capturing mineral deposits and sediment from your water supply, this pad helps prevent those minerals from being dispersed into your home's air as white dust. It acts as a primary filter to keep your indoor environment cleaner.

It is not recommended to clean and reuse these cellulose pads. Once the material is clogged with mineral deposits, it loses its ability to absorb water effectively, and attempting to wash it often damages the structure of the pad.
