Recommended pairing
Cold plunge water collects debris and impurities, so many people run the filtration system alongside the Frozin Chiller. The chiller holds temperature from 37 to 60 degrees but doesn't clean water, and both connect on the same 3/4 inch hose plumbing.

Is this right for you?
You'll get the most from it if
- Your plunge water clouds between changes and you want fewer full drains.
- You run a Frozin 400 or another tub with 3/4 inch fittings and want water kept circulating.
- Plan for filters as a small recurring cost; a couple of swaps a year keeps it doing its job.
Maybe look elsewhere if
- Buying your first setup? The Frozin Complete System includes this filtration out of the box.

From the Journal
Why it earns a place in the stack. Cold exposure only pays off when you get in, and nobody plunges into murky water. This system quietly handles the unglamorous part, pumping water through a filter that traps debris so the water stays clear plunge after plunge. Swap the filter every few months and the coldest part of your routine stays the easiest to keep.

Our approach
Every product earns its place.
No single thing changes your biology on its own. What matters is the system, and whether each piece earns its place. Here is how a device makes it into Kove.
01
Start with the evidence
Where there is research behind how something works, we read it. We look at the real mechanism a device relies on, like the wavelength, the frequency, or the dose, and whether the evidence holds up. Substance comes before marketing, and we are honest about how strong that evidence is.
02
Separate mechanism from marketing
A claim is not a mechanism. We check a device's real output against its stated one: does the panel emit the 660 and 850nm it advertises, at the irradiance that makes those numbers matter? The marketing language gets set aside. The measurable spec is what we judge.
03
Verify build and dose
Even a good idea does nothing if the hardware is weak. We confirm the output is consistent, the dose is usable in a real daily routine, and the build holds up over years, because a device only helps if it lasts as long as the habit.
04
Held to one standard
What clears every step earns its place in the system, held to the same standard as everything else. That consistency is what you can count on.
