Balboa Purezone

With this Purezone system you only need to purchase one of each part; Hover, Dock, Cassettes, and then after that you just need to get replacement cassettes as you need to.

Purezone is an innovative, fully automated water quality monitoring system engineered for hot tubs and spas. Designed to eliminate manual testing and guesswork, it ensures safe, perfectly balanced water with real-time insights—right from your smartphone.

Monitors Key Parameters Automatically
Track pH, free chlorine, total alkalinity, and bromine—no test strips, no manual calibration. Each unit uses an optical sensor that self-calibrates before every test.

Real-Time Alerts & Smart App Control
Get instant notifications, historical trends, exportable reports, and personalized maintenance advice, all through the intuitive Purezone mobile app.

Fully Automated Operation
Drop it in, dock it inline—Purezone does the rest. The system uses smart replaceable cassettes (48 tests per cassette) and alerts you when it’s time to swap.

Tailored for Any Use Case

• Purezone Hover: A floating, self-contained unit perfect for personal or residential spas.

No calibration. No manual tests. No surprises. Just crystal-clear data—and water.

• Floating water testing system with built-in optical sensor.

• Uses replaceable cassettes (30 tests each)
• No test strips, no plumbing modifications, no manual cleaning.

Automated Accuracy

Purezone self-calibrates with every test cycle—no dip strips, no fiddly sensors, and no manual recalibration. It’s a consistent and reliable way to monitor your water, eliminating the margin for human error.

Peace of Mind & Time Saved

Instead of testing the water manually day after day, Purezone does the job for you. All the important data is available at a glance through the app, wherever you are. It’s quietly working in the background, running regular tests and logging results for when you need it most.

Built for Compliance

Purezone measures Parts Per Million (PPM) instead of Oxidation-Reduction Potential (ORP)—a critical difference for meeting health and safety standards in professional settings. The Dock version fits securely inside the filter housing, offering a tamper-resistant solution that’s ideal for holiday lets, rental properties, or any setup with guests.

Smart Insights & Recommendations

The app doesn’t just show you numbers—it gives guidance based on your spa’s setup. You’ll get treatment suggestions tailored to your water condition, reducing chemical waste and improving long-term water quality.

Flexible & Adaptable

Testing frequency is fully adjustable: daily, every two days (the default), weekly, or whatever suits you. Each cassette delivers 48 tests, and the system even tracks how many you’ve got left—so you’re never caught short.

Forward-Thinking Spa Tech

Purezone is the start of something new. It’s the first system of its kind available in the UK that sits directly in the spa water—no plumbing modifications, no complex installs. By blending automation, app integration and exportable data, it brings hot tub care into a smarter, simpler future.
