How to Use & Care

Before first use, rinse the filter thoroughly with clean water and discard the water. To filter water, fill the outer container, then slowly press the inner bottle with the filter attached into it. This forces the water through the filter and into the inner bottle, ready to drink.

After use, press the bottle 2–3 times without water to push air through the filter and remove any remaining moisture. Then detach the filter element from the other components and leave it exposed to air until completely dry.

Only use freshwater. Do not filter water above 40°C, and protect the filter from freezing.

How It Works

Two Filtration Stages. Two Different Processes.

The Selfpress combines two filtration technologies. The 0.2 µm hollow fibre membrane physically traps bacteria, protozoa, microplastics and particles. An activated carbon block provides the second stage, using its large internal surface area to adsorb certain dissolved substances. This helps reduce chlorine and substances that affect the smell and taste of water.

Together, mechanical filtration and activated carbon adsorption form a two-stage filtration system.

  • Activated carbonReduces chlorine and improves taste.
  • Independently Lab-TestedLog 8 reduction of E. coli.

Your Filter Over Time

  1. AFTER EVERY TRIP Leave to Dry

    Press air through the filter 2–3 times to expel any remaining moisture. Then detach the filter element, leave it exposed to air until completely dry and store it separately from the other components.

  2. UP TO 1,500 LITRES Maximum Capacity

    The maximum filter capacity is 1,500 litres. Its actual lifespan depends on the quality of the water being filtered.

  3. BLOCKED WATER FLOW Time to Replace

    With regular use, the membrane pores gradually become clogged, reducing the water flow. When water can no longer be pressed through the filter, it's time to replace the filter element.

  4. STORAGE At Least 2 Years

    When stored correctly, the filter element has a shelf life of at least 2 years. If the filter has been used, it is important to dry it promptly and thoroughly before storing it.

Your Filter Helps Bring Clean Water to Nepal, Too.

1% of every order goes to Viva con Agua

You filter your own water, whether from a stream or while travelling. For many families in western Nepal, access to clean drinking water cannot be taken for granted. That's why we support Viva con Agua Switzerland's drinking water project, providing clean drinking water, toilets and hygiene education for villages and schools.

So far, the project has reached 100,000 people in village communities and 21,000 schoolchildren across 105 schools in western Nepal.

Frequently Asked Questions

What Makes the Selfpress Different from Other Water Filters?

The BACHGOLD Selfpress Water Filter combines everything you need in one convenient system. There are no external hoses or complicated components to deal with. In just a few seconds, you have filtered water ready to drink straight from the bottle.

How Long Does the Filter Element Last with Regular Use?

The Selfpress 500 ml has a maximum filter capacity of 1,500 litres, equivalent to approximately 2,500 uses.

How Do I Know When to Replace the Filter?

You'll know it's time to replace the filter when pressing requires noticeably more effort. Over time, particles and deposits gradually clog the fine pores of the filter membrane. This reduces the water flow and makes the bottle increasingly difficult to press.

How Long Can the Filter Element Be Stored When Not in Use?

When stored correctly, the filter element has a shelf life of at least 2 years.

What Should I Do If Water Overflows During Filtration?

Make sure the water does not exceed the fill line on the outer container and that there is no air trapped between the water and the filter element before you start pressing. Check that the sealing ring on the filter element is correctly positioned and keep the drinking cap open throughout the filtration process.

What Materials Is the Selfpress Made From, and Where Is It Manufactured?

The Selfpress 500 ml is made from BPA-free plastics (PP and ABS), silicone and silicone gel. The Selfpress XL is made from polypropylene, which is also BPA-free. Both models are designed and developed in Switzerland and manufactured by our partner in China.

Can I Use Soap or Vinegar Essence to Clean the Filter?

No. Do not use soap or concentrated vinegar to clean the filter element, as these can cause permanent damage. Clean water is all you need.

Which Replacement Filter Do I Need?

You need the same filter element as the one originally supplied with your Selfpress. For the Selfpress 500 ml, choose the BACHGOLD Selfpress Replacement Filter. For the Selfpress XL, choose the BACHGOLD Selfpress XL Replacement Filter.

Does the Selfpress Also Filter Viruses?

No. The Selfpress uses a hollow fibre membrane and activated carbon. It reliably filters out bacteria and protozoa but offers only limited virus reduction. If virus filtration is important to you, particularly when travelling to distant destinations, we recommend our Squeeze or Straw. Both use a two-stage filtration system that also effectively filters out viruses.

[View the Squeeze]

Can I Use the Selfpress to Filter Tap Water While Travelling?

Yes, the Selfpress can generally be used to filter tap water while travelling. The hollow fibre membrane traps bacteria and protozoa, while the activated carbon reduces chlorine and substances that cause unpleasant tastes and odours.

However, the Selfpress provides only limited virus reduction. In regions where tap water may also be contaminated with viruses, we recommend our Squeeze instead.
