Minimax softeners don’t just provide soft water around the clock - they’re the only softeners in the world that guarantee it’s completely soft, all the time. While one cylinder is regenerating, the other keeps softening. That means you’ll have softened water 24/7, even during the regeneration process.

Whether it’s one bathroom or four power showers running at once, Minimax softeners handle it with ease - delivering unbeatable flow without a hint of hardness breaking through.

Forget heavy bags and messy refills. Minimax softeners use high-purity block salt - either traditional or the patented Curve blocks - making top-ups cleaner, lighter, and easier.

Unlike many other systems, the Minimax is designed to run beautifully without the need for annual servicing - saving you time, money, and hassle. We typically see a Harvey softener coming in for its first service somewhere between 12-18 years! That's pretty good going, in our books!

No plug? No problem. Minimax softeners run purely on water pressure - no wires, no programming, and no need to reset after a power cut.

By pushing water upward - rather than down like most softeners - Minimax delivers a more complete exchange, zero internal riser tubes, and visibly softer results.

Minimax softeners don’t just track water use - they measure even the tiniest trickles, for perfectly soft water, all the time.
