The Frozin Cold Plunge Filtration System combines a 650 GPH circulation pump with a 20-micron replaceable filter cartridge to keep cold plunge water clean and actively circulating. Designed for use with the Frozin 400 and compatible with most 50–150 gallon cold plunge setups, it removes debris, oils, and particulates before they cloud the water or reach your chiller. The result is cleaner water that lasts longer between changes and a chiller that operates more efficiently over time.

- Replaceable filter cartridges are easy to access and swap without tools
- Compatible with the Frozin 400 and most standard cold plunge and DIY setups
- Suitable for both indoor and outdoor use
Product Highlights
20-Micron Replaceable Filter Cartridge
The 20-micron filter captures fine particulates that pass through coarser filtration, including skin cells, hair, and small debris. The cartridge housing is designed for quick access so filter changes take seconds, not minutes.
650 GPH High-Flow Circulation Pump
The 650 Gallon Per Hour pump moves water continuously through the filtration system and back into the tub. Active circulation prevents stagnation and supports even temperature distribution throughout the water volume.
Broad Setup Compatibility
The system uses standard hose connections and is designed to integrate with the Frozin 400, most hard-sided cold plunge tubs, and DIY chest freezer setups in the 50–150 gallon range. No custom fittings are required for most installations.
Chiller Protection
By filtering particulates out of the water before it re-enters the chiller circuit, the system reduces the risk of debris accumulation inside chiller components. This supports consistent cooling performance and reduces maintenance demands on the chiller unit.
Low-Maintenance Design
The filter housing is designed for straightforward access. Cartridge replacement requires no special tools and can be completed quickly, keeping downtime between sessions minimal.

Important Information
- Ensure all hose connections are secure and leak-free before powering on the pump.
- Do not run the pump dry. The system must have water flowing through it before the pump is activated.
- Replace the filter cartridge on a regular schedule based on usage and water quality. A clogged filter will reduce pump efficiency and water clarity.
- The pump requires a standard grounded electrical outlet. Do not use with an undersized or damaged extension cord.
- Place the filtration unit on a stable, level surface. Keep it clear of standing water and direct rain exposure when used outdoors.
- This system is designed for cold-water applications only. Do not use with heated water or hot tub setups.
- Keep out of reach of children. Do not allow children to operate the pump or handle filter cartridges.
- Inspect hoses and fittings periodically for wear, cracking, or leaks.
Frequently Asked Questions
Is this filtration system compatible with the Frozin 400 cold plunge tub?
Yes. The Frozin Filtration System is designed to work with the Frozin 400 and uses standard hose connections that are compatible with most other hard-sided cold plunge tubs and DIY setups in the 50–150 gallon range.
Can I use this system with a water chiller?
Yes. The filtration system can be used alongside a water chiller. Placing the filter upstream of the chiller helps prevent debris from entering the chiller’s internal components, which supports consistent cooling performance over time.
How often do I need to replace the filter cartridge?
Replacement frequency depends on how often the tub is used and the condition of the water. As a general guideline, inspect the cartridge regularly and replace it when flow rate noticeably decreases or the cartridge appears visibly saturated. Refer to the included documentation for the manufacturer’s recommended schedule.
Does this system replace the need to drain and refill the tub?
The filtration system significantly extends the time between water changes by removing particulates that would otherwise accumulate. However, periodic draining and refilling is still recommended as part of routine water maintenance, particularly for high-frequency users.
Is this system suitable for a DIY chest freezer cold plunge?
Yes. The system uses standard connections and is compatible with most DIY cold plunge builds, including chest freezer conversions in the 50–150 gallon range. Verify your setup’s hose port sizes before purchasing to confirm compatibility.
Can I use this system outdoors?
Yes. The system is suitable for outdoor use in a garage, on a patio, or in a backyard setting. Place the unit on a stable, level surface away from standing water and direct rain exposure. In freezing ambient conditions, drain the system when not in use.
Does the pump run continuously?
The pump is designed to run continuously while the system is powered on, keeping water circulating through the filter at all times. This continuous circulation is what allows the filter to capture particulates effectively and maintain water clarity between sessions.
The Frozin Cold Plunge Filtration System is a practical, well-specified solution for anyone who wants cleaner water and less time spent on tub maintenance. If you use a cold plunge regularly and want to extend water life while protecting your equipment, this system is a straightforward addition to your setup.
