🧊 What Is a Cold Plunge System with Chiller and Filter?
At its core, a cold plunge system includes:
A chiller to cool and circulate water
A filter to trap debris and maintain water clarity
A pump (built-in or external) to drive flow
A plunge tub that matches water volume and insulation needs
Using a filter is essential to protect the chiller and maintain sanitation. Without it, hair, dirt, and organics can clog the water line or even damage internal parts.

🔄 Choosing the Right Filter for Cold Plunge Chillers
When connecting your tub and chiller, the filter is your water’s first line of defense. For this setup, we recommend:
Cartridge filter (20–50 micron) for fine debris removal
Transparent housing for easy inspection
Sealed connections to avoid suction loss
Mesh filters may be reused for short-term setups, but for long-term daily plunging, cartridges outperform on clarity and protection.

🧰 Installation Tips for Cold Plunge Filtration Systems
To avoid the most common issues—like flow alarms or airlocks—follow these best practices:
Place the filter on the suction line before the chiller
Keep hose lengths short and minimize bends
Prime the pump properly and bleed air after install
Check all clamps monthly and replace filter biweekly
