Product Overview

A Simple Maintenance Essential for The Immersion Tub

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

Because the Immersion Tub circulates water through its built-in filtration system, 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 Immersion Tub was designed to deliver.

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

Why You'll Love it!

Designed Specifically for The Immersion Tub

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

5" Diameter x 7" Tall

Each filter measures 5" in diameter x 7" tall, making this the correct replacement size for the Immersion Tub 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 Immersion Tub’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 NW Immersion Chillers

These filters are not compatible with NW Immersion Chillers. They are intended only for The Immersion Tub.

Why Replace Your Immersion Tub Filter?

Cleaner Water, Better Flow, Better Ownership Experience

Your filter is one of the most important maintenance parts in your Immersion Tub. 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

The Immersion Tub by NW Immersion

Not Compatible With

NW Immersion Chillers
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 Immersion Tub 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 Immersion Tub owners, keeping a 2-pack on hand is an easy way to stay prepared for routine maintenance.
