Why sailors, hikers and globetrotters rely on Pi technology in miniature form

Water you can trust: even when you’re out and about

You go hiking in the mountains. You camp by the lake. You sail on the sea. You travel through countries where you don’t know the water. In all these situations, one thing remains constant: you need to drink.

Tap water in some countries is questionable. Bottled water is expensive, it’s heavy to carry, and it leaves plastic everywhere. There is a third way: MAUNAWAI travel filters.

Filter bottles for hikers, campers and world travellers

Imagine this: you fill your bottle from a lake and the water is immediately drinkable. Clean. Pure. Safe. You don’t need a campfire to boil it. You don’t need chemicals. You just need your MAUNAWAI travel filter bottle.

These bottles are robust. They’ll last a day’s hike. They’ll last a week’s camping. They’ll last a round-the-world trip. The material has been chosen to be lightweight – not so light that it breaks, but light enough for you to carry it all day long.

The Pi technology principle, in miniature format

The principle is not new. It is the same Pi technology that works in our larger systems, only compressed into a portable format. Activated carbon from coconut shells removes chlorine, heavy metals and organic contaminants. Mineral ceramics regenerate the water and restore the structure it has lost on its journey through pipes.

Mountain springs from the Alps? Works. Seawater from Scandinavia? Works. River water from tropical countries? Works. The system works because it is based on natural principles, and these apply equally everywhere. Of course, a travel bottle is no substitute for a drinking water treatment system designed for heavily contaminated water. But for typical situations on the go – a clear mountain lake, a campsite tap, a spring on a hiking trail – it is just right.

Peace of mind

When you’re travelling in a foreign country, you know the feeling: can I drink the water here? With a MAUNAWAI travel filter bottle, you have an answer that puts your mind at ease. Instead of relying on expensive bottled water in plastic, you filter your own water, right there on the spot. This gives you independence. You’re no longer dependent on the nearest supermarket. You’re no longer relying on the quality of local water sources. You always have your own water purification system with you.

For adventurers and conscious travellers

Those who drink MAUNAWAI water have a different relationship with water. It’s not just a liquid you have to drink. It’s something that nourishes you. You notice this even when you’re on the move. You feel better. You’re more alert. Your digestion is happy.

Some people say: That’s psychological. Perhaps. But psychology is real too. And if good water makes your adventure better, then it’s worth it.

Sustainable travel

A travel filter replaces dozens of plastic bottles. A single trip with a MAUNAWAI filter bottle saves more plastic than the average person produces in a month. Multiply that over years, across millions of travellers, and it’s not insignificant. It’s significant.

Different sizes for different adventures

There are travel filters for short day trips. Bottles for longer expeditions. Systems for different climate zones. Not every trip is the same, and MAUNAWAI has a solution for every situation. The compact bottle for the day trip. The more robust system for multi-day hikes. And for yacht owners and sailors: filters that can also cope with brackish water and varying water sources.

An advantage that is often overlooked: MAUNAWAI travel filters also make sense in everyday life. In the office, at the gym, whilst playing sport – wherever you want to improve tap water without installing a large system. Simply fill it with tap water, and the integrated filter does the rest.

For sailors and yacht owners

One particular group deserves a mention: sailors and yacht owners. On the water, the water supply is always a challenge. Tank water quickly goes off, harbours offer varying water qualities, and space for water crates is limited on boats. MAUNAWAI travel filters solve this problem elegantly. Run the tank water through the filter, and you’ll have fresh, revitalising drinking water on board at all times. No extra storage space, no extra weight, and no compromise on quality.

Connection to our philosophy

This is perhaps the best example of the MAUNAWAI vision. Nature as a model, everywhere. Not just at home. Outdoors too. In the wilderness too. Even when you’re far from home.

For us, filtering water is not a business model. It is a philosophy. It is the conviction that good water is a fundamental right, not a luxury. Not something that only rich people in rich countries are allowed to have. But something that a hiker in the Alps can have. A camper by the lake. A sailor on the Atlantic. A traveller in countries where clean water is not a given.

Practical details

The bottles are made from robust, food-safe materials that are built to last. They are easy to clean: a brush and warm water are all you need. The filters are replaceable and can last for several months, depending on how often they are used. Once you’re back home, you can continue to use the bottle as an everyday water bottle, with or without the filter. Nothing goes to waste.

And one more thought on sustainability: every MAUNAWAI travel bottle used instead of a single-use plastic bottle saves dozens of bottles over the course of a trip. Multiplied over years and thousands of travellers, this amounts to a considerable amount of plastic that does not need to be produced, transported or disposed of. This is no marginal saving. It is a conscious contribution to reducing plastic waste on hiking trails, on beaches and in the world’s oceans.
