A Simple Maintenance Essential for your NW Immersion Chiller

Clean, clear plunge water starts with consistent maintenance. The Replacement Filters help support proper water circulation and filtration in your NW Immersion Chiller.

Because the NW Immersion Chillers circulate water through their built-in filtration systems, filter condition matters. A clogged or overdue filter can reduce water flow, make filtration less effective, and affect the overall ownership experience. Replacing filters regularly helps preserve the clean, reliable performance your NW Immersion Chiller was designed to deliver.

This 2-pack makes it easy to keep your maintenance routine simple and consistent.

Designed Specifically for NW Immersion Chillers- 1HP & 2HP

These replacement filters are made for NW Immersion Chillers and are designed to support the proper fit, flow, and filtration required by the chiller.

2.5" Diameter x 10" Tall

Each filter measures 2.5" in diameter x 10" tall, making this the correct replacement size for the NW Immersion Chiller filtration system.

Sold as a 2-Pack

Each order includes 2 replacement filters, so you can replace one now and keep one ready for your next maintenance cycle.

Supports Cleaner Water

Regular filter replacement helps capture debris, particles, and buildup that can affect water clarity.

Helps Maintain Proper Flow

A clean filter supports proper water circulation through the NW Immersion Chiller's filtration system.

Important for Routine Maintenance

Filters are consumable maintenance items and should be rinsed and replaced as needed based on use, water quality, and maintenance habits.

Quick and Easy to Replace

Designed for straightforward routine maintenance so you can spend less time managing your tub and more time using it.

Not for The Immersion Tub

These filters are not compatible with The Immersion Tub. They are intended only for NW Immersion Chillers- 1HP & 2HP.

Why Replace Your NW Immersion Chiller Filter?

Cleaner Water, Better Flow, Better Ownership Experience

Your filter is one of the most important maintenance parts in your NW Immersion Chiller. As water circulates, the filter helps collect debris and particles that would otherwise remain in the tub or move through the filtration system.

Replacing your filter regularly helps:

  • Maintain better water clarity
  • Support proper circulation
  • Reduce restricted water flow
  • Support filtration performance
  • Improve the overall plunge experience
  • Keep the tub ready for daily use

If your water looks cloudy, flow seems reduced, the filter looks discolored, or it has been in use for several weeks, it may be time to rinse or replace your filter.

Compatible With

  • NW Immersion Chillers- 1HP & 2HP

Not Compatible With

  • The Immersion Tub
  • Other chiller brands
  • Other cold plunge tubs
  • Aftermarket chiller systems
  • Filter housings requiring a different filter size or style

If you are unsure whether you have The Immersion Tub or a separate NW Immersion chiller system, contact us before ordering so we can help confirm compatibility.

Recommended Replacement Schedule

Filter life depends on how often your Plunge is used, whether users rinse before entering, water care routine, outdoor exposure, and overall water quality.

General guidance:

  • Rinse the filter regularly, especially with frequent use
  • Replace the filter when visibly dirty, discolored, clogged, or flow is reduced
  • Keep extra filters on hand so maintenance is never delayed
  • Replace more often for shared-use, outdoor, or high-frequency plunge setups
  • Replace sooner if water clarity drops or the system seems to be circulating less effectively

For most residential NW Immersion Chiller owners, keeping a 2-pack on hand is an easy way to stay prepared for routine maintenance.
