UVC & CD Ozone Sanitisation System

Most swim spas make clear water an unpleasant trade-off: harsh chemicals, red eyes and that lingering chlorine smell. The Endless Pools® UV-C and CD Ozone System ends the compromise with dual-action sanitisation working silently inside the plumbing — ultraviolet light kills bacteria on contact while CD Ozone continuously neutralises contaminants, purifying the water before it ever touches your skin. With far fewer harsh chemicals, the water feels silky, smells fresh, and stays gentle on sensitive skin and young eyes.

Gentler on sensitive skin
Gentler on sensitive skin

For anyone with sensitive skin, a heavily chlorinated pool can mean dryness, tightness and irritation after every swim. Because the UV-C and CD Ozone system neutralises contaminants and kills bacteria automatically, far fewer chemical additives are needed to keep the water clean. The water feels silky rather than harsh, so you can swim daily without the after-effects that put sensitive skin off the water.

Easier on allergies and sensitive lungs
Easier on allergies and sensitive lungs

For anyone sensitive to chlorine, the problem is not just the water, it is the air above it. As heavily dosed water off-gasses, it releases the sharp chemical smell that can leave allergy sufferers and sensitive lungs feeling irritated, especially in covered or sheltered spaces. Because the UV-C and CD Ozone system relies on far fewer added chemicals, there is much less of that off-gassing to contend with. The result is fresher air around the water and a more comfortable swim for people who usually find chlorinated pools hard going.

An invisible guardian, always on
An invisible guardian, always on

The UV-C and CD Ozone system works like an invisible guardian, running quietly inside the plumbing to purify the water before it ever reaches you. It does not switch off between swims, so your water is continuously cleaned around the clock rather than only when you remember to treat it. This always-on purification gives you confidence that the water is fresh and clean every time you step in, with none of the guesswork of manual dosing.
