Does block salt contain any impurities?

Harvey block salt is of a very high quality, because we want it to contribute to the optimal performance of your water softener. Other brands may contain additives. 

Our salt is Grade A, food quality salt compliant with BS EN973. Unlike some salt blocks, ours contains no anti-caking agents or harmful minerals that could damage your softener. We only source salt from trusted suppliers to ensure the best quality product.

The amount of salt you need to top up your water softener will depend on the model and size of the softener you have installed. It also depends on how many people are in your household and how much water they typically use.
