The sustainable alternative for softer water in residential applications.

Product Information

UV Guard’s HWC-Home Series is an innovative WaterMark-certified hard water conditioning solution suitable for a wide range of residential uses. Unlike conventional water softening processes, the HWC-Home Series produces soft water whilst requiring no electricity, salts, resins, magnets, backwashing or ongoing maintenance.

  • Provides softener water through a unique process
  • Multiple models for whole house, shower and appliance use
  • Easily installed inline within your home
  • Maintenance and power free with zero running costs
  • 24/7 operation with no interruptions to water treatment process
  • No added salt or other chemicals required
  • Valuable minerals are not removed from your water


The HWC-Series is a highly effective way to reduce water hardness in and around your home. Water hardness is typically caused by dissolved Calcium and Magnesium minerals. High concentrations can lead to issues with limescale and scale deposits. Hard water scaling can be a concern around the home as it can cause blockages in pipes, premature appliance failures, scum rings in swimming pools and baths, heating element deterioration and a host of other entirely-preventable problems.

The HWC-Home Series is ideally suited for:

  • Drinking water – improve the taste and smell of your tap water
  • Washing machines – softer water means softer, more comfortable laundry
  • Dishwashers – eliminate hard water spots on newly-washed glassware and dishes
  • Bathrooms – less skin irritations, cleaner hair and improved water flow/pressure
  • Bath tubs, showers, sinks & basin – remove and prevent scale, stains and soap scum
  • Swimming pools – reduce the use of chemicals, prevent scale build-up and increase the life of your pool pump
  • Home plumbing – remove years of scale build-up within your existing pipework and protect heating elements in your appliances.

What is ‘Hard Water’?

Water hardness is typically caused by dissolved Calcium and Magnesium minerals. High concentrations can lead to issues with limescale and scale deposits. Hard water scaling is a concern across many industries as it can cause damage to UV systems, blockages in pipes, premature appliance or equipment failures, scum rings in public swimming pools, heating element deterioration and other costly problems in commercial situations.

UV Guard Applications

Our market-leading UV disinfection systems deliver outstanding results across an extensive range of industrial, commercial and domestic applications.


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.

Ray, WA

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.

Allison, NSW

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.
