Kinetico Block Salt is a high-purity, compact solution for your water softener needs. Each 4 kg block dissolves gradually to deliver consistent soft water, preventing limescale build-up and extending the lifespan of your appliances. Compatible with Kinetico and Harvey water softeners, this cost-effective product is designed for ease of use and minimal maintenance. Two blocks of salt are typically used at a time, offering long-lasting performance and reducing the need for frequent refills.
