Minimax Water Softeners - Outstanding Water Efficiency
Traditional single-cylinder water softeners typically use between 70–120 litres of water every time they regenerate (that’s when they flush out the chalk and limescale they’ve collected). Not only is this a waste of water, but it also takes time — usually 55–85 minutes per cycle.
By contrast, systems like the Kinetico Premier and Aqua-Blu use significantly less — around 24–26 litres per regeneration. While these brands sometimes publish lower figures (like 21 litres), that often excludes the backwash stage, which is essential for softeners using American valve systems. The reason they don't publish the full figure is the Harvey softener doesnt need to backwash, unlike the American Kinetico, and so they show their figures on a like for like basis. They usually take 12-15 minutes per regeneration
Minimax M3 and MiniMax Innova
But, here’s where the MiniMax M3 and MiniMax Innova truly shine:
They use just 17.1 litres of water per regeneration — and take only 11 minutes to complete the cycle. This incredible efficiency is thanks to the highly accurate displacement metering system built into every MiniMax softener. It measures precisely how much water you’ve used and regenerates accordingly — no guesswork, no backwashing and no extra waste.
Minimax Major and Minimax Big Blue
And it’s not just the compact models that impress — the MiniMax Major (designed for larger homes and higher flow rates) uses just 37 litres of water per regeneration, while the MiniMax Big Blue uses only 50 litres! That’s a fraction of what many larger softeners use. In fact, the most popular alternative softeners to the Big Blue on the market, designed for similar-sized water usage, uses over 365 litres of water per regeneration — more than seven times as much! The difference in water waste (and cost) adds up fast.
Why it matters:
-
Lower water bills
-
Faster recovery time
-
Kinder to the environment
-
Less strain on your plumbing system
-
The Minimax range are perfect for septic tank systems too as they use just 1L of brine water (M3/Innova) - and Harveys give a written guarantee about that compatability too!
