Water care

Clean, clear water.
For months.

Every AirTub filters and circulates its water around the clock. Here is how to keep it fresh with almost no effort.

  • 24/7Circulation and filtration
  • 30–40daysWith the included filter
  • 3–4monthsWith UV XL + Ozone

How it works

A closed water loop, always moving.

Filtered first, then cooled, then back to the tub. Around the clock.

Water lifespan

How long your water stays fresh.

For normal home use, when everyone gets in clean, ideally after a shower. Getting in sweaty or without a shower shortens these times; good hygiene extends them.

  • Filter only Included30–40 days
  • Filter + UV XL2–3 months
  • Filter + Ozone2–3 months
  • Filter + UV XL + Ozone3–4 months

For gyms, spas and other shared use, we strongly recommend UV XL, Ozone or both.

Changing water

Empty and refill with one garden hose.

Emptying is easy. Open the valve and let the water run out right there, or connect a garden hose and lead it wherever you like. Then refill from any tap.

FAQ

Water questions

Do I need chlorine or chemicals?

No. AirTub is designed to run with filtration, and optionally UV XL and Ozone, which sanitise the water without adding chemicals.

Should the system stay on all the time?

Yes. Keep it plugged in and switched on. Cooling pauses at your target temperature, but circulation and filtration continue 24/7, which is what keeps the water clean.

Can I add UV XL or Ozone later?

Yes. Both are Plug & Play add-ons: they connect to your AirTub and a standard power outlet, whenever you decide.

Why is the filter placed before the chiller?

So that hair and debris are caught before they reach the pump and heat exchanger. This protects the chiller and keeps the flow steady.

How often do I replace the filter?

Every 30–40 days, or sooner if it looks clearly darker or holds visible debris. Use IceHab filters only: they fit exactly, and other filters can reduce flow and void the warranty.

What happens when I travel?

Enter your away dates in the app. Cooling stays off during that period, while circulation and filtration keep the water clean.
