Buy water treatment online – for camping, hiking & travel

Whether you want to buy a lightweight water filter for hiking, put together emergency equipment for long-distance travel or find a robust purification system for a family camping holiday: the range covers mechanical hollow fiber filters, UV purifiers, chemical tablets as well as spare parts and suitable accessories. So whether you're a hiker, camper, traveler or emergency prepper, you'll quickly find the right solution for different areas of use, water quality levels and group sizes – conveniently from home.

Water treatment by area of use

For solo hikers and ultralight trekking, compact hollow fiber filters like the Katadyn BeFree or Sawyer Squeeze, which fit directly onto water bottles and weigh only a few grams, are ideal. For multi-day trips and medium-sized groups, powerful pump filters and gravity systems from MSR and Platypus are particularly popular. For travel in regions with uncertain water quality, combined filter-purification systems like the Grayl GeoPress or the MSR Guardian offer comprehensive protection. For emergency preparedness and stationary applications, chemical purification tablets from Aquamira and durable ceramic filters from Katadyn are proven solutions.

Buy water filters & compare purification systems

There is a strong focus on mechanical water filtration with hollow fiber membranes, which reliably remove bacteria and protozoa – without any chemicals, waiting time or unwanted aftertaste. If you need additional virus protection, you'll find special filters with corresponding barriers or supplementary chemical purification agents. Whether you want to buy a water filter, order a UV device, or specifically reorder spare parts and cleaning accessories for an existing system – the selection offers the right solution for every requirement.

Who is this category for?

This category is ideal for outdoor enthusiasts, hikers, trekking fans and campers in Switzerland who want to obtain clean drinking water from natural sources on the go. At the same time, travelers to remote regions, emergency preppers and families at campsites will find a wide selection of water treatment systems that are precisely tailored to their needs.

Quality, safety & product selection

When buying a water treatment system, it's worth paying attention to tested filter standards, the membrane pore size and any certifications according to recognized standards. Equally important are the expected water quality on site, the desired flow rate and the easy maintenance of the system – this way the water treatment fits exactly the planned area of use and ensures worry-free drinking enjoyment on the go.

Frequently Asked Questions

What methods of water treatment are there for camping and hiking?▾

The most common methods are mechanical water filters with hollow fiber membranes, chemical purification with tablets or drops, UV irradiation with handheld devices and boiling water. Each method has its own advantages – mechanical filters work instantly and without waiting time, while chemical processes are particularly lightweight and space-saving.

What is the difference between a water filter and water purification?▾

A water filter physically removes particles, bacteria and protozoa from water, usually through a hollow fiber membrane with a defined pore size. Chemical purification kills microorganisms using active ingredients such as chlorine or silver ions. Combination systems unite both processes for comprehensive protection.

Which water filter is best for hiking and trekking?▾

For hiking and trekking, lightweight, compact filters like the Sawyer Squeeze, Katadyn BeFree or Platypus QuickDraw are ideal. They weigh only a few grams, fit into any backpack and can be combined directly with water bottles or hydration systems – perfect for on the go.

How does a water filter with a hollow fiber membrane work?▾

A hollow fiber membrane consists of thousands of microscopically fine tubes with pores in the range of about 0.1 to 0.2 microns. Water is pressed through these pores while bacteria, protozoa and sediments are retained. The result is clean drinking water without chemicals or waiting time.

Can I also remove viruses with an outdoor water filter?▾

Most standard outdoor water filters reliably remove bacteria and protozoa due to their pore size, but not viruses. For regions with viral contamination, special filters with a virus barrier, chemical disinfectants or combination solutions such as the MSR Guardian or Grayl GeoPress are recommended.

How do I properly maintain and store my water filter?▾

After each trip, the filter should be backflushed with clean water to prevent clogging. For storage, let the filter dry completely – opened in an airy place, but without direct sunlight. Protect from frost, as freezing residual water can destroy the membrane. Some models can be descaled with a vinegar solution.

What should be considered when treating water while travelling abroad?▾

In tropical and subtropical regions, the risk of viruses and other pathogens is higher. Therefore, a filter with virus protection or a combination of filtration and chemical purification is recommended. Water turbidity also plays a role: heavily contaminated water should be pre-filtered or sedimented before disinfection.

Which water treatment is suitable for groups and families?▾

For groups and families, more powerful systems like the Katadyn Pocket, MSR AutoFlow or gravity filters from Platypus are ideal. They deliver large quantities of drinking water in a short time – several liters at once – and are robust enough for daily use in base camps or at family campsites.
