Two stages, total confidence
The 0.01-micron membrane handles the dangerous stuff: bacteria, microplastics, sediment. The carbon layer handles chlorine and off-tastes. Clean, and it tastes like it.

Why Aquanaut
Same science. A completely different reason to own it.
We didn’t build Aquanaut for the apocalypse. We built it for Tuesday, and for your next flight.
Made for the move
No batteries to charge, no pump to prime, no tablets to wait on. Fill, sip, go. The whole system lives in one leak-proof bottle.
Not just for “out there”
Microplastics turn up in most US tap water. Aquanaut isn’t a once-a-year emergency tool. It’s your everyday glass, upgraded.
How it works
Two stages. One sip.
Fill from any tap, fountain or stream, and the filter goes to work instantly. No batteries, no pumping, no waiting.

Hollow-fiber membrane microfilter
A dense bundle of microscopic tubes with 0.01-micron pores physically strains out bacteria, microplastics, sediment and cloudiness. It’s tested to remove 99.999999% of bacteria. Anything larger than the pores simply can’t pass.

Activated carbon stage
Reduces chlorine, bad tastes and odors, and low-concentration chemical pollutants, so the water tastes clean, not just is clean.
Reduces chlorine · tastes · odorsA note on honesty — what it does not do
Like all hollow-fiber filters, Aquanaut is not designed to remove viruses or dissolved heavy metals and salts. For everyday tap water and the great majority of travel destinations, the real threats are bacteria, parasites and particulates — exactly what the two-stage system targets. Performance figures are being finalized against the supplier’s test report.
The everyday upgrade
You don’t have to leave the country to drink better.
Around 94% of US tap water samples test positive for microplastics, and bottled water can carry several times more. Aquanaut isn’t a bottle you bury in a drawer between trips. It’s the one you reach for at your desk, at the gym, and at the kitchen sink.
- Filtered for the everydayYour desk, your gym, your kitchen sink, not just the trail.
- Better than bottledSkip the single-use cycle without trading down on what you drink.
- Hold your water to a standardYou filter your coffee and read your labels. Same idea.

“Two weeks across Vietnam and Thailand, filled it from every hotel tap, and not a single bad day. It basically paid for itself in skipped bottled water.”
