ScaleArmor Rock – Salt-Free Anti-Scale Media
Protect taps, showers, boilers and appliances from limescale build-up with ScaleArmor Rock, a mineral-based, salt-free anti-scale media. Designed for inline housings and refillable canisters, it conditions hard water to help reduce scale adhesion on metal and glass while keeping healthy minerals in your water.
- Salt-free anti-scale media for hard water areas
- Helps reduce limescale on taps, showers, kettles & heating surfaces
- No power, no drain, low maintenance
- Suitable for inline filter housings / refillable cartridges
- Food-grade media with minimal pressure drop
- Typical service life: 6–12 months (usage & hardness dependent)
Why choose ScaleArmor Rock
- ✔ Cut down on lime deposits on shower screens, taps and appliances
- ✔ Improve efficiency by reducing scale on heating elements and pipework
- ✔ Easy fit into standard inline housings or a refillable cartridge
- ✔ Salt-free & maintenance-light — no regeneration cycles
- ✔ Great with filters — pair with sediment/carbon pre-filtration for best results
Best for
- • Homes in hard water areas seeking simple scale reduction
- • Showers, bathroom fittings and glass where spotting is an issue
- • Kitchen appliances (kettles, coffee machines, dishwashers)
- • Pre-treating water before a boiling tap or instant hot unit
How it works
As water flows through the media bed, calcium and magnesium hardness are conditioned, which reduces their tendency to stick to surfaces as hard scale. You’ll still keep beneficial minerals, but cleaning becomes easier and heating surfaces stay cleaner for longer.
Installation & sizing
- Install in a clear inline housing or refillable cartridge on the cold feed you wish to protect (e.g., kitchen cold, appliance feed, or whole-house pre-treat if sized correctly).
- Use with a sediment pre-filter to prevent fouling and extend media life.
- Observe flow direction and allow enough contact time for conditioning.
- Replace media when you notice scale returning faster than usual or at 6–12 months intervals based on usage and local hardness.
Care & maintenance
- Check the housing quarterly for clarity and flow.
- Replace the media on schedule; refresh sediment/carbon pre-filters as required.
- For guaranteed limescale removal, see our water softener range below.
Want 100% guaranteed limescale removal?
For households looking for total protection from hard water, a water softener is the only system that completely removes calcium and magnesium. Enjoy scale-free showers, spotless glass, and longer-lasting appliances.

Frequently asked questions
Is ScaleArmor Rock a water softener?
No — it’s a salt-free anti-scale conditioner. It helps reduce the adhesion of hardness as scale, but it does not remove hardness minerals like a traditional ion-exchange softener.
Where should I install it?
On the cold feed serving the fixtures/appliances you want to protect (e.g., kitchen cold, appliance line, or sized for whole-home pre-treat). We can advise on the best location.
Do I still need pre-filters?
Yes — a sediment pre-filter is recommended to prevent fouling and to maximise media life. A carbon filter can be added for taste/odour improvement.
How long does the media last?
Typical life is 6–12 months, depending on usage, flow rate and local hardness. Replace sooner if you notice scale returning more quickly.
