The Culligan Arc
Water Softener

Discover the innovative and convenient approach to enjoy the benefits of softened water in your home.

Say farewell to limescale, cut energy costs by up to 30%, and extend the life of your appliances while experiencing the gentle touch of soft water on your skin and hair.​

The Culligan Arc Water Softener is a premium electricity-free solution that employs twin-tank technology to provide a continuous flow of soft water around the clock.​


Advanced softening technology

Experience advanced water softening with our Smart Shuttle Technology, ensuring maximum flow rates from your softener. Our advanced resin beads, made from the highest-grade resin, capture limescale particles more efficiently. ​

And with a parallel system that guarantees a constant supply of fresh water and a twin-cylinder design for uninterrupted 24/7 soft water.

​Convenient curved salt blocks

Easier to carry, load, and store – our lightweight curved salt blocks are more convenient than standard block salt and fit seamlessly into your Culligan Arc water softener. ​

You can trust that, just like all our salt products, it’s sourced from dependable suppliers and crafted to the highest quality standards.


The Culligan Arc’s cabinet is crafted from recycled, clean-sourced Polypropylene. The unit also features accurate metering, which ensures zero water wastage. ​

The Smart Culligan Arc boasts an exterior that uses 38% less plastic, with 62% of it originating from recycled sources, helping repurpose plastic waste that would otherwise end up in landfills.

Compact design

The Culligan Arc Water Softener benefits from a modern, compact design, providing professional-grade performance that fits neatly under most kitchen sinks.

Greener living

By reducing limescale in your home, the Culligan Arc enhances the efficiency of your heating system and appliances, ultimately lowering your carbon footprint and cutting down on utility bills.

Limescale-free water

Limescale-free water not only preserves the longevity of your appliances and plumbing but also leads to softer skin and shinier hair. Additionally, you’ll notice a reduction in the need for cleaning and maintenance, making daily life more convenient and cost-effective.
