History
From 2018 – 2025, JED Engineering ozone generators were widely used by cold-plunge builders following clear ventilation and safety guidelines. JED has since changed its business focus and no longer supplies ozone generators for the cold-plunge or DIY market.
As a result, those models are no longer available here.
If you already own a JED ozone system, nothing about its use has changed. Continue following the same outdoor or well-ventilated installation practices and manufacturer safety guidance you’ve always used.
Going forward, this page highlights current ozone options and alternatives that meet the same core goals: clean water, simple setup, and responsible use.
CP-Brain: A Modern, Integrated Ozone Solution
As the cold-plunge space continues to mature, more builders are looking for sanitation solutions that are simple, self-contained, and professionally designed, without the complexity of custom plumbing or multiple separate components.
The CP-Brain prototype was built in 2023 and has been undergoing testing and refinements since then. I’ve been using one since early 2025 and fully recommend it. See this link for my full YouTube video review:
CP-Brain is an integrated ozone-based sanitation unit that combines a circulation pump, ozone generator, tubing, and diffuser into a single, compact system. It is designed specifically for water sanitation and is intended for outdoor use or very well-ventilated environments, following the same basic ozone best practices the cold-plunge community has used for years.
Why CP-Brain stands out
- All-in-one design. No venturi injectors, bypass loops, or custom plumbing
- Consistent ozone dosing appropriate for cold water volumes
- Simple setup for professionally built or purpose-designed plunge systems
- Reduced installation complexity, especially for builders and manufacturers
- Designed as a system, rather than a collection of off-the-shelf parts
When used correctly for water sanitation only, and installed in appropriate environments, systems like CP-Brain offer a straightforward way to maintain clear, low-odor water with minimal ongoing intervention.
Professional evaluation in progress
As part of ongoing due diligence, a demo CP-Brain unit is currently being sent to Desert Plunge for hands-on evaluation and testing. This allows experienced builders to assess real-world performance, reliability, and maintenance considerations before making any long-term decisions.
I’ll continue to share practical insights and field observations as that testing progresses.
Important note on use
As with any ozone-based system:
- Use outdoors or in well-ventilated areas
- Operate only for water sanitation, not air treatment
- Follow manufacturer guidance on run times and placement
- Avoid direct inhalation of ozone
These are the same common-sense principles that have guided responsible ozone use in water applications for many years.
