Life with a Big Blue water softener
It uses the same unique twin cylinder design as the UK’s number one selling HV4 model which allows for both cleaning & softening simultaneously, ensuring that your home enjoys an uninterrupted supply of softened water.
The Big Blue water softener fits to the mains water supply, and can still fit easily under your kitchen sink despite its size. It only needs tablet salt to function, which can be replenished when it runs out by simply dropping the salt into the top of the water softener.
All of our water softeners are manufactured in Britain by Harvey Water Softeners who have over 40 years of experience, so you can trust that we’ll get it right.
