Electrodes are the heart of your Claritech NEC-20 purification system. Over time, they naturally wear down as they release copper-silver ions into your pool water. These official Claritech Replacement Electrodes restore your system to full effectiveness — so your pool stays clean, clear, and chemical-free for years to come.
Why Replace Your Electrodes?
✅ Restore full purification power — worn electrodes reduce ion output and effectiveness
✅ Official Claritech replacement — guaranteed compatibility with your NEC-20
✅ Extend the life of your system — a fraction of the cost of a new unit
✅ Easy to install — simple swap, no specialist required
What Does It Cost Over Time?
At $1,249.99 with a lifespan of 2–3 years, that works out to roughly $415–$625 per year — often less than what pool owners spend annually on chlorine, stabilisers, acid, and replaced equipment. Copper-silver ionisation is a long-term investment in cleaner water and lower ongoing costs.
