Minimax Major : Powerful. Practical. Surprisingly Compact.
The Minimax Major is designed to meet the needs of larger households and smaller businesses, delivering consistent soft water when the demands are high
The MiniMax Major’s flexible twin-cabinet design shown side by side.
In this image, you’re seeing the block salt model: the smaller cabinet holds the salt, while the larger cabinet houses the softener.
If you choose the tablet salt version, both cabinets are of the taller size.
The MiniMax Major is designed for homes with up to four bathrooms or small commercial spaces like B&Bs and clinics.
It’s compact, flexible, and capable of delivering beautifully softened water — even when multiple taps and showers are running at once.
Unlike traditional large softeners, the Major doesn’t need lots of space. Its versatile split cabinet design gives you full flexibility — install the salt tank separately, or even outdoors, if needed. And because it’s non-electric, it runs simply and silently, powered only by your water pressure.
