The Culligan HarveyArc is a Made in Britain, next‑generation non‑electric water softener designed to deliver high‑performance limescale reduction for homes with 1–3 bathrooms. Built with a twin‑cylinder, parallel system, it provides a continuous, uninterrupted supply of softened water, even during regeneration—ensuring round‑the‑clock comfort and protection for appliances, plumbing, and surfaces.

To maximise efficiency, the Arc uses smart shuttle metering to measure every drop of water, preventing waste and optimising regeneration cycles. Its advanced resin bead technology enhances limescale removal, while the eco‑cabinet, made from 62% recycled polypropylene, reduces environmental impact without compromising strength or durability.

The system features the WiFi‑enabled i‑Lid, which connects to the myHarvey app for automatic salt‑level monitoring—eliminating manual checks and making maintenance simple and intuitive. Tested to over 1 million cycles, the Arc surpasses British Standards for resilience and reliability, making it a long‑term, low‑maintenance solution for homes in hard‑water areas. It includes a 3‑year manufacturer warranty, with an optional extension for added peace of mind.
