Easy to carry, easy to store, easy to load

Harvey’s original block salt is the easiest way to keep your Harvey Water Softener running softly and smoothly. Our salt is sourced from trusted suppliers, manufactured to the highest quality and delivered to your door in just a few days

We actually invented block salt for water softeners, so we really know what we’re doing.

Each pack contains 2 salt blocks - each block weighs 4kg.
One person will use 1 salt block per month, but can vary depending on your water usage.
Grade A / food quality salt (standard BS EN973).
Delivery included.

Our original block salt is compatible with most other Harvey and Non-Harvey Water Softeners, but if you have a HarveyArc Water Softener then you'll need Mini Curve Salt. Please view our compatibility chart for more information.
