Keep your cold plunge water clean and clear with this easy-to-install bath water filter kit—designed for tubs and chillers, with a 20-micron cartridge that traps dirt, debris, and more.
You'll notice reduced water flow or a slight change in water clarity when the cartridge is due for replacement. For best results, check your filter every month and swap the cartridge if you see buildup or slower circulation.
Simply open the air release valve on the filter to allow water to flow in. When the water level inside the filter stabilizes and stops rising close the valve. This ensures no air pockets remain inside the filter, allowing smooth water flow and effective filtration.
Absolutely. By filtering out dirt and impurities before they reach the chiller, this filter prevents clogging and wear, helping extend the life and efficiency of your equipment.
For optimal performance, we recommend replacing the cartridge rather than cleaning and reusing it, as the 20-micron fibers trap very fine particles that are hard to fully remove.
Yes! Our filter kit is compatible with any cold plunge system using standard 1/2 fittings, making it easy to upgrade or add filtration to your custom or DIY tub and chiller.

I had questions about whether this would work with my setup before ordering. The information I received helped me feel confident
I originally ignored accessories and focused only on the chiller. After using the setup for a few months I realized good filtration matters just as much
I did not buy this when I first got my plunge and honestly wish I had. After using it regularly I realized water maintenance is a big part of the experience

A simple upgrade that makes daily cold plunging much more convenient. Easy to use and a great addition to my chiller system

Now the water stays crystal clear for much longer and it honestly saves me a ton of time on maintenance. It is a simple addition that makes a huge difference in the overall experience.
A must-have upgrade. The 20-micron filtration really pulls out the fine sediment that my previous basic filter missed. Water is crystal clear.
Water stays noticeably cleaner even after multiple uses. I used to change water way too often, but now it actually stays fresh for weeks.
The filter was an easy addition to my setup and has helped keep the water clearer. I like that I can enjoy my plunge without thinking about cleaning it all the time.
Honestly didn’t think accessories would matter this much, but the skimmer and filter combo keeps the tub way cleaner. Less maintenance, more actual cold plunging.
The replacement process is super fast and hassle-free. It fits my setup perfectly and works smoothly.
Great quality and super affordable—finally found the right one!
