Complete Minimalist Filtration System

The Ultimate Cold Plunge Filtration System 

 All-in-One, Plug-and-Play Convenience

Clean Water for 1-Year+ Without Draining

The APEX86 Complete Minimalist Cold Plunge Filtration System is a compact, submersible 1200 GPH filtration system designed for chest-freezer cold plunges, ice baths, stock tanks, and other at-home plunge tubs. It combines 5-micron mechanical filtration, high-flow circulation, a washable pre-filter, and an ozone-ready Venturi in one plug-and-play system that installs without tools.

2-Minute Setup. No Tools Required.

Designed for simplicity and efficiency, our filtration system is up and running in just two minutes—no tools, plumbing experience, or complicated instructions required. Everything arrives in one box, ready for immediate installation. Whether you're a beginner or an experienced cold plunger, this system streamlines your setup and helps maintain clean, crystal-clear water with minimal maintenance.

Compact, Powerful, and Efficient

Despite its compact footprint, this system packs serious power. The robust USA made 1200 GPH pump provides optimal circulation, while the included filtration element efficiently removes particles and debris down to 5-micron skin cells! Its space-saving design ensures it doesn’t get in the way of your plunging experience—just clean, cold water exactly when you need it.

Customizable Venturi Hookup Options

This system includes a high-flow venturi attachment, giving you flexibility depending on how you want to oxygenate or sanitize your water:

• Ozone Compatible: Add your own ozone generator (like the recommended JED 103) to inject ozone directly into the water for advanced sanitation.
• Air Injection Only: Skip the ozone and run a simple air hose to the venturi for continuous air injection—great for oxygenating your plunge without additional equipment. (available as an add-on)
• Outlet Diverter Only: Leave the venturi unconnected to use it purely as a directional water outlet.

Multiple Placement Options for Maximum Flexibility

This filtration system is designed to work with virtually any cold plunge setup. You can place the APEX86 system:

• On the Step of Your Freezer: Ideal if you have at least 9.5 inches of water above the step. The filter will face down for optimal function.
• On the Floor of Your Plunge: Perfect for setups without a step or with lower water levels. Place the unit with the filter facing upward. Note: for best venturi performance, keep water depth to around 22 inches or less, as too much depth can reduce venturi injection.

Filter Maintenance & Replacement

Recommended replacement filters (5-micron) can be found here.

If the venturi stops producing bubbles, it’s likely time to clean or replace the filter. To clean: rinse with water and soak in a mild bleach solution ~3oz bleach inside the housing, topped off with water; for 2 hours. Repeat every 2 weeks to maximize filter life.

Important

Usage Notes

• Hand wash filtration components only with warm, soapy water. Avoid hot water or dishwashers, as high temperatures may damage plastic parts.
• Safety first: Always unplug the pump, freezer, and any connected devices before entering the water.
• Never run the pump dry. It must always be submerged in water to prevent damage not covered by warranty.
• Pump is 120V only. For countries using 220V–240V power, a step-down transformer rated for at least 300W or 3 amps is required.
