The HWC-Series took a few weeks to clean the calcium build-up from the pipes and the results were astonishing. I honestly cannot speak more highly of the product and installation was so easy.

Since installing the water conditioner we are using less washing powder, soap and shampoo. The life of our hot water element also appears to have been extended.

Sally, WA

Since installing our Shower Water Conditioner, the whole family has noticed the difference. We all have softer, more manageable hair and my son no longer has as many skin irritations.

Before installing UV-Guard’s Hard Water Conditioner, Calcium used to build-up on every surface, Iron was also staining our toilets and basins. Now there is no Calcium build-up and the Iron staining is easily wiped away.
