Safir water-softener salt is made from high purity PDV rock salt. Our water softener salt helps remove minerals from your hard water, including iron,  calcium, magnesium, and even barium. These hard
water minerals are removed when water passes through resin beads in the water softener tank.

The salt blocks are made of very pure salt and have been developed especially for the softening of water for human consumption and water used in the food industry.
