Spa & Hot Tub Water Purification NZ
Spa & Hot Tub Water Purification in New Zealand
Your spa should be a place of relaxation — not a chemical experiment. Claritech’s NEC-20 delivers crystal-clear, skin-friendly water for spas and hot tubs using virtually chemical-free copper-silver ionisation technology — reducing your chemical usage by up to 90%.
The Problem with Traditional Spa Chemicals
- Chlorine causes skin irritation, red eyes, and strong odours
- Chemical costs add up to hundreds of dollars per year
- Harsh chemicals degrade spa components over time
- Storing pool chemicals at home is a safety risk
The Claritech Solution
The NEC-20 is purpose-built for spas and above-ground pools, optimally rated up to 20,000L. It automatically releases copper and silver ions that destroy bacteria, algae, and biofilm — dramatically reducing the chemicals your spa needs. Suitable for larger pools too — electrode lifespan reduces proportionally with pool volume.
- Virtually chemical-free — reduce chemical usage by up to 90%
- No harsh chlorine — no smell, no irritation, no red eyes
- Gentle on skin — safe for children and sensitive skin
- Fully automated — set and forget, even while on holiday
- Made in Germany — ISO 9001 certified, 40+ years of proven technology
Do I Still Need Any Chemicals?
Yes — a small amount. The Claritech system destroys bacteria and algae, but a minimal dose of an oxidiser (like non-chlorine shock) is still needed weekly or after heavy use to break down dissolved organic waste like sunscreen, sweat, and body oils. Heated spa water accelerates organic buildup, so staying on top of it weekly keeps things effortless. You’re not going back to a chemical-heavy spa — just a fraction of what you used before.
