Founding run — 1,000 bottles

The travel bottle that cleans your water.

In half the world you can’t drink the tap. Fill it anywhere, press the cap, two minutes.

UV-C light in the cap destroys what’s living in the water — the same class hospitals use. It re-runs every two hours on its own.

Why it works

Everything treats the water. Nothing treated the bottle.

So we built the one that does both — and runs itself, because the thing you carry all day is the one thing you can’t wash over there.

Boab Bottle in hand
A light in the cap
A 280nm UV-C LED breaks bacterial DNA so it can’t multiply — the same class of light hospitals use.
Sixty seconds, then again every two hours
Fill it, press the cap, done. Then it re-runs on its own, whether you remember or not.
You can see it working
A blue ring glows while the cycle runs and goes out when it’s finished.
Steel, and still cold at 3pm
316 stainless sheds nothing into your water, and stays cold for 24 hours.

Why not buy plastic, like everyone else?

Because it's clean for about an hour. After that it's a warm bottle of your own bacteria — and you'll buy 30 of them.

Your mouth loads it on the first sip. Then it sits in a 30-degree bag for twenty hours, in the range where bacteria double every twenty minutes.

And the seal only proves the cap is on. The CDC notes that bottled water “might not be superior to tap water” in some places, and that some bottles “contain tap water added by unscrupulous vendors.”

240,000
plastic fragments per litre of bottled water. 90% of them nanoplastics — small enough to pass through your gut into your blood.
~8,000,000
particles over an eleven-day trip, at three litres a day.
30
bottles per traveller, per trip. Left on an island that has to deal with them.

A 2024 PNAS study found ~240,000 plastic fragments per litre in bottled water.

You can't fix the plastic already in the world's water.

You can fix what you're adding on purpose.

Compare it to the thing you already buy.

You'll spend about A$90 insuring the flights and never think about it again. That's insurance against something that probably won't happen.

This is the same money, against something that happens to roughly half of travellers.

And unlike the trip, it doesn't end at the airport. The gym. Work. The next trip, and the one after that. Australians now average four trips a year.

You're not buying it for eleven days.

Questions

Five of these are supplier specs and one is a warranty decision. They are flagged, not invented.

This is the last thing on the list.

You’ve done the ice, the salads, the bottled water, the toothbrush at midnight. This is the only one you can actually cross off before you go.
