The Mavren Approach

You don't have to be a prepper
to want to be prepared.

Mavren isn't a bunker brand. We don't sell fear, we don't do camo, and we don't think you need 30 days of freeze-dried food in your garage.

We make the gear you'll be glad you have if the power's out for a week, or the water comes back brown for three days, or you just want to feel competent the next time the news gets scary.

Start with water. Everything else can wait.

How it works

It works the same way you'd drink through a straw.

Because that's exactly what it is. No pumps, no power, no setup.

1

Submerge

Place the bottom of the filter into any freshwater source.

2

Sip

Draw water through the filter. The 4-stage filtration happens in seconds.

3

Clear

Blow back through the mouthpiece after each use to keep the membrane clean.

Quietly competent. No bro-marketing nonsense.

Bought after a long hurricane week with no clean tap water. Use it on weekend hikes now too.

Honest about what it doesn't do. That's why I trust it.

Every other filter brand I've looked at oversells. Mavren is the first one I'd actually hand to a family at an evacuation centre.

Léa M. · Marseille, FR

Survived our Brisbane flood, twice.

Lives in the laundry cupboard with our emergency kit. Easier to use than I expected.

Erin C. · Brisbane, AU

The packaging alone made me trust it.

Feels like Bellroy made a water filter. I keep it on the shelf, not hidden in the garage.

Sarah J. · Bristol, UK

Built like German tools should be.

After the Ahr valley floods, I won't be the family without one again.

Tobias H. · Köln, DE

The floods hit and we were ready.

Boil-water notice for nine days after the cyclone. The kids didn't notice anything was different.
