Advanced Features
Many features of this product make it unique, so let's look at those in detail:
Mini-Curve Block Salt
Lighter, purer, and easier to store — the curved salt is smarter, cleaner, and better for your softener.
Innova’s patented salt arcs offer easier handling, improved purity (99%+), and better protection from poor-quality imports.
They’re lighter, fit more inside the cabinet (holding 4 blocks vs 2), and cost less more than traditional blocks.
Best of all, they protect your softener guarantee from the damage caused by using the wrong salt!
Refilling is quick and clean. Just drop in the new arcs — no fuss, no spills.
Reduced Carbon Footprint
MiniMax Innova doesn’t just care for your home — it’s built to tread lightly on the planet too.
New recycling technology, coupled with its clever design, reduces the Minimax Innova’s footprint on our planet by cutting plastic usage by a massive 38%. It is also made from 62% recyclable materials, including recycled Polypropylene from a clean source, making it the most environmentally friendly cabinet on the market!
Smart iLid + myHarvey App
Monitor salt levels, battery life, wi-fi signal and more - all from your phone or tablet. Receive alerts, order salt, and even request service, right from within the app! (Powered by 4 x AAA batteries - no electricity required).
Smart-Shuttle Metering & Accurate Flow Sensing
Designed for British plumbing, Innova measures from the tiniest drips to powerful unvented systems — ensuring maximum efficiency with minimal waste. Flow rates stay high, pressure drop stays low.
Advanced Resin Bead Formula
Top-grade, chlorine-resistant resin — guaranteed for 10 years. It softens more efficiently and lasts longer, even in challenging water conditions.
Industry-leading Impact Testing
Tested to 1 million cycles at 15 bar, the Innova surpasses every industry standard for pressure and performance — built for decades of use.
Twin-Cylinder, Always-Soft Design
No downtime, no hard water breaks — just beautifully softened water 24/7, thanks to its dual-cylinder non-electric system overseen by the amazing William Sargeant at Harvey Softeners
Non-Electric & Backwash-Free
Runs on water pressure alone. Unlike imported systems, it doesn’t require unnecessary backwashing — saving water and helping you meet future efficiency standards.
Built in Britain. Trusted by Experts.
Manufactured in Woking, Surrey and hand-assembled by engineers who genuinely care.
That’s the power of softened water — gentler on sensitive skin, better for bath time, and kind to your little ones.
Having walked around the factory hundreds of times while managing the dealer network at Harvey's, I got to know the factory team personally very well. I'm very proud that my business, Hydroworks, has been selected as just one of 28 companies in the UK to be an Elite Dealer of the Harvey Softener brand and that we can bring you the best of the industry’s technology.
While we are independent and sell every make and model of softener to our customers, the litmus test for what Hydroworks recommends is based on what I would put into my own home, or my folks' home for that matter (or my in-laws!!).
