Minimax Big Blue : Commercial power. Domestic simplicity.

Perfect for the commercial sector, or for homes with seriously high water demands - due to its bigger salt storage capacity - more infrequently accessed locations.

See inside the Minimax Big Blue: twin-cylinder precision engineering built to deliver continuous softened water, without electronics, noise, or complexity.

The MiniMax Big Blue is our highest-capacity softener, ideal for homes with up to six bathrooms, or light commercial settings.

We now have several dozen launderettes and hotels plus care homes, and factories using this softener, including one Royal Estate, and it's a firm favourite due to its salt and water efficiency and delivers consistently soft water without the noise, bulk, or energy waste of older commercial softeners.

This is the ultimate non-electric softener — capable of delivering up to 10,000 litres of softened water per day, while using surprisingly little salt and water.

Advanced Features

These are some of the features of the Minimax Big Blue:

Commercial-Level Performance

The Minimax Big Blue delivers more than most dedicated commercial systems — without their complexity or running costs. It’s a perfect upgrade from older, less efficient softeners.

Single Cabinet, High Capacity

Despite its output, the Minimax Big Blue has a sleek, self-contained cabinet with a large salt opening and easy-access design — neat, simple, and easy to maintain.

Scalable Installation

Need more than one? No problem. The Minimax Big Blue units can be linked together to suit larger hotels, care homes, or higher-demand environments — giving you flexibility as your needs grow.

Outstanding Salt Efficiency

One of the most common pieces of feedback we receive: “It uses far less salt than our old commercial softener.”

That’s the MiniMax effect.

Continuous Soft Water

With its twin-cylinder setup, the Minimax Big Blue ensures zero downtime — so there’s no hard water during regeneration.

Proven Durability

Tested to 100,000 cycles at 10 bar, like the MiniMax Major, and built to last with minimal servicing.
