🔧 Professional Installation
With over 20 years installing water treatment systems across Nicosia, Limassol, Larnaca, and Paphos, we know what Cyprus water demands. The NU-1 Ultra is built for local conditions — hard water, chlorine-treated municipal supply, and the need for reliable, low-maintenance filtration.
Why the NU-1 Ultra Works for Cyprus Water
Cyprus tap water is safe, but it’s not perfect. TDS levels across the island range from 300 to 450 mg/L, and chlorine is added at treatment plants to keep it safe. That means your water can taste and smell like a swimming pool. Hard water minerals also leave scale on kettles, in coffee machines, and inside pipes. The NU-1 Ultra tackles all of these — removing chlorine, reducing scale, and giving you cleaner water at the tap. Whether you’re in Nicosia, Limassol, or Larnaca, this system is designed for your water.
🧪 Chlorine Taste & Odour
Cyprus water is chlorinated at source. The NU-1’s NSF-certified ACF removes up to 99% of chlorine, so your water tastes fresh — not like a public pool.
🧱 Hard Water Limescale
Limescale is a fact of life in Cyprus. The anti-scaling media in the NU-1 Ultra helps reduce scale build-up in your pipes, kettle, and coffee machine.
🦠 Bacteria & Microplastics
Optional 0.01-micron UF membrane removes bacteria, viruses, and microplastics — extra protection if you’re concerned about water quality beyond chlorine.
💧 Bottled Water Replacement
Cyprus households spend hundreds on bottled water every year. A filter under your sink gives you better-tasting water for a fraction of the cost.

NU-1 Ultra vs Reverse Osmosis — Honest Comparison
| Feature | NU-1 Ultra | Reverse Osmosis |
|---|---|---|
| Chlorine, Taste & Odour Removal | ✅ Excellent | ✅ Excellent |
| TDS / Dissolved Salt Reduction | ❌ Minimal | ✅ 99% reduction |
| Limescale (Hardness) Reduction | ✅ Reduces scale deposition | ✅ Removes hardness minerals |
| Bacteria & Microplastics | ✅ With UF option | ✅ Yes |
| Retains Natural Minerals | ✅ Yes | ❌ No — but remineralisation filters available |
| Flow Rate | Up to 4 L/min | 0.5–2 L/min (tankless) / 2–3 L/min (with tank) |
| Waste Water | ❌ None | ✅ 2:1 to 3:1 waste ratio |
| Installation Complexity | Simple DIY | More complex, often needs professional |
| Running Cost (annual) | Cartridge change — ~€[ADD_PRICE] | Cartridge + membrane — slightly higher |
| Best For | Chlorine removal, taste improvement, retaining minerals, low waste | High TDS, heavy metals, nitrates, very hard water — with remineralisation if needed |
Bottom line: If your main concern is taste, chlorine, and you want a simple, low-waste system, the NU-1 Ultra is a great choice. If you have very hard water, high TDS (over 500 mg/L), or want the purest possible water, reverse osmosis is the more powerful option — and you can add a remineralisation cartridge to restore minerals. Running costs are similar, with RO slightly higher due to membrane replacement.

Maintenance — What to Expect
The NU-1 Ultra is low-maintenance. The main ACF cartridge lasts for 10,000 litres or 12 months, whichever comes first. In Cyprus, where water consumption varies by household, we recommend changing the cartridge annually for best performance. If you add the optional UF membrane, it also lasts up to 12 months — we recommend replacing both at the same time.
| Part | Replacement Interval |
|---|---|
| ACF Cartridge | 10,000 litres or 12 months |
| Ultrafiltration Membrane (optional) | 12 months (replace with ACF cartridge) |

NU-1 Ultra — Frequently Asked Questions
Is the NU-1 Ultra suitable for Cyprus water?
Yes. The NU-1 Ultra is designed to remove chlorine, bad taste, and odour from municipal water. It also features anti-scaling media to reduce limescale build-up — a common issue with hard water across Cyprus.
What does the NU-1 Ultra remove?
The ACF cartridge removes chlorine, bad taste, odour, and organic compounds. The optional UF membrane removes bacteria, microplastics, and particles down to 0.01 micron. It also includes anti-scaling media to reduce limescale.
How is the NU-1 Ultra installed?
It installs under your kitchen sink, connecting to the cold water supply with a G 3/8″ fitting. The kit includes a universal tee-adapter and all hardware. Professional installation is available across Nicosia, Limassol, Larnaca, and Paralimni.
How often does the filter need replacing?
The main ACF cartridge lasts up to 10,000 litres or 12 months. The optional UF membrane also lasts 12 months — we recommend replacing both at the same time. Replacement cartridges are available from WaterFilterNet.
How does the NU-1 Ultra compare to reverse osmosis?
Reverse osmosis is the more thorough technology — it removes dissolved salts (TDS), heavy metals, nitrates, and hardness minerals, typically achieving 90–98% reduction. The NU-1 Ultra removes chlorine, taste, odour, and (with the UF option) bacteria and microplastics, but it does not reduce TDS. RO produces waste water and requires more maintenance, while the NU-1 Ultra is simpler and wastes no water. Running costs are similar, with RO slightly higher because the membrane is replaced annually. If you choose RO, you can add a remineralisation filter to put back healthy minerals. The right choice depends on your water quality and priorities.
Does the NU-1 Ultra reduce limescale?
Yes. The built-in anti-scaling media helps reduce calcium and magnesium build-up in your pipes, kettle, and coffee machine. It protects your plumbing and appliances from hard water damage.
Do you deliver and support the NU-1 Ultra across Cyprus?
Yes. We deliver across all of Cyprus with free delivery via Primewell Courier. Professional installation is available in Nicosia, Limassol, Larnaca, and Paralimni. We stock genuine replacement cartridges and provide local support from our Cyprus base.
Does it need electricity to work?
No. The NU-1 Ultra is a non-electric system that works on cold water pressure alone. No power outlet or wiring is required for installation or operation.
