FAQs OF COLD PLUNGE CHILLER
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 like that this feels like a practical accessory instead of an unnecessary add on. It helped me build a better maintenance routine
I am so glad I picked up this filter upgrade. Keeping the water clean was becoming a real chore before I installed this. 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.
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.
This was a simple upgrade that made maintaining my plunge much easier. I use my setup often and this helps me spend less time worrying about water care
This upgrade does exactly what it promises. My water stays cleaner and smells fresher throughout the week. I am giving it four stars because I wish the instructions for the initial installation were just a tiny bit clearer but once I figured it out it has been working like a charm.

Setup was easier than I expected, and everything has been running smoothly since day one. Just take your time during installation and follow the instructions.
Before adding this, I was constantly checking the water and cleaning more often than I wanted. This filter helps keep everything looking fresh and makes owning a plunge tub much easier.
I added this filter to my plunge setup and noticed the difference pretty quickly. The water stays cleaner between changes, and I spend much less time worrying about maintenance. A small upgrade that makes a big difference.
The cartridges are easy to replace, and the housing feels well-built. Since installing it, the water stays cleaner and there's less visible sediment in the tub. Definitely worth adding to any cold plunge system.
I added this filter to my cold plunge setup about a month ago and wish I had done it sooner. The water clarity improved almost immediately, and I don't have to clean the tub nearly as often. The replacement process is simple and takes less than a minute.
I bought the pump + connection kit and it solved all my flow issues. Before that I had weak circulation, now everything runs consistently and the chiller doesn’t struggle.
The filter system made a huge difference. Water stays clean way longer and I don’t have to change it as often. Super simple upgrade but it improves the whole setup a lot.
The filter upgrade works great and has made a noticeable difference in keeping my plunge water cleaner for longer. I do replace the cartridge regularly to maintain the best performance, but that's a simple part of the routine. Overall, the water stays much clearer, and maintenance is much easier than before. Definitely a worthwhile upgrade for anyone using a cold plunge regularly.
