TheraFrost Flow Filtration & Ozone System
- Fresh water every plunge: a strong pump keeps it circulating
- Fresh water every plunge: a strong pump keeps it circulating
- Fewer drain and refill days: filters out debris and particles
- Chemical-free water care: a three minute ozone cycle sanitizes
- Keep your tub: it connects to the plunge you already own
Keeping standing ice-bath water clear
Standing water is the weak point of any ice bath: debris settles, films form, and the tub slowly becomes a chore. The Flow's pump pulls water through its filtration so particulates get caught instead of sinking, and 3-minute bursts of concentrated ozone sanitize the water, no chemicals to measure or dose. It adds no heating or cooling, just the upkeep that keeps you plunging.
The Flow manages water quality only; it does not treat, cure, or prevent any condition.

Description
The TheraFrost Flow is an ice bath filtration and ozone system that keeps the water in the cold tub you already own clear and fresh, plunge after plunge. It pairs a high-powered circulation pump with advanced filtration and chemical-free ozone purification in a single add-on unit.
One thing to know: the Flow handles circulation, filtration, and ozone purification only. It does not chill or heat water. If you want active cooling that holds temperature, look at the TheraFrost Cold Plunge with its built-in chiller. But if your routine already includes a tub and ice, this is the simple way to keep your water clean week after week. Upkeep stays light: let the pump circulate, run an ozone burst when you want to sanitize, and clean or replace the filters as water quality dictates.
Key details
TheraFrost Flow Filtration & Ozone System is an add-on filtration, circulation, and ozone unit for an ice bath you already own. A high-powered circulation pump moves water through a filtration stage that collects debris and particulates. Water care is chemical-free: the system runs concentrated ozone in 3-minute bursts whenever you choose to run one. It connects to your existing tub and has no heating or cooling function of its own, so it does not change water temperature. Upkeep is limited to letting the pump circulate, running an ozone burst, and cleaning or replacing the filters as water quality dictates.
It fits routines built around recovery.
Is this right for you?
You'll get the most from it if
- More than one person uses your plunge; shared tubs foul faster, and circulation keeps pace between changes.
- Ice runs do not bother you; you just mind murky water more than hauling bags.
- You have power within reach of the tub; the Flow sits alongside it and needs its own outlet.
Maybe look elsewhere if
- You want water chilled and held at temperature; the Flow filters and circulates, and the TheraFrost Cold Plunge handles the chilling.

From the Journal
Why it earns a place in the stack. Cold exposure only works as a habit, and murky water is where habits quietly end. The Flow keeps the cold half of a recovery routine ready, circulating, filtering, and ozone-sanitizing the tub you already own. No chemicals to dose, fewer drain-and-refill days, just water that stays clear enough to keep getting in.

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.
