Water reserves provide security. Water treatment creates independence.
The Federal Office of Civil Protection recommends a water supply of 20 liters per person for ten days. An important reserve, but one that shrinks with each passing day and is tied to a single location.
Yet water is often available: from rain barrels, wells, streams, or other freshwater sources. The key is being able to purify it safely in an emergency, independent of electricity and without having to transport large quantities of water.
That is why, in addition to a water supply, a means of water purification should be part of your emergency preparations. Because when you need it, it should already be close at hand.
- 20 kilogramsThat is how much the water supply for ten days weighs. Anyone who has to leave suddenly can hardly take that with them.
- Up to 500 litersfrom a rain barrel, canister or stream, with a single Straw.
- Around 100 gramsFits in any emergency kit and is always with you on the go.
Known from
Two filter stages. Two operating principles.
The Straw combines two different filter technologies. An electro-adsorptive filter fleece uses positively charged fiber surfaces to bind very small, negatively charged contaminants to its surface. This is complemented by an activated carbon block, which can reduce odors and tastes in the water, among other things. In this way, electro-adsorption and activated carbon work together in a two-stage filter system.

- Activated carbonRemoves chlorine and improves taste
Drink directly from a stream, canister, or rain barrel.
With 70 cm hose
Straw gold
The filter goes directly into the water, while the straw stays with you. This is an advantage especially at brooks and flowing water sources: You don't have to bend down or lie on the ground to reach the water, but can drink comfortably while standing or sitting.
Standard filter straws
Tubeless construction
Drinking directly from the water source. It works well from a bucket or a rain barrel. At a creek, it quickly becomes cumbersome. You have to get close to the water, bend down or lie down, and if the current is strong, drinking becomes difficult.
As many as you need.
Anyone who orders for two gets a free straw for the car.
One per person
The Straw is intended for personal water supply. Everyone drinks directly from their own filter, at a rate of around 0.2 liters per minute. Therefore, every emergency bag should contain its own Straw.
One for the car
Small enough for the glove compartment. At around 100 grams and under 19 centimeters, the Straw is always with you without taking up space.
From the cupboard to the emergency.
-
During storage Dry and protected from sunlight
Keep it handy in your emergency bag, in the glove compartment, or with your supplies.
-
In an emergency Two rounds, then drink
Attach the hose, hold the open end in the water, and drink directly through the filter.
-
After drinking Dry and store securely
Blow through with air, remove the filter element, and allow to air dry. Then store in a dry place.
-
Up to 500 liters The maximum, not the rule
The Federal Office of Civil Protection calculates 20 liters per person for ten days. The Straw manages up to 500 liters.
-
When hardly any water is getting through Then the straw is used up
Hardly any flow despite cleaning? The filter may have reached its capacity. Since the filter element in the straw is not replaceable, the straw must be replaced in this case.
Capacity and maintenance according to instructions for use. Stockpiling quantity according to the Federal Office of Civil Protection and Disaster Assistance.
Your filter also provides water in Nepal.
1% of every order goes to Viva con Agua
You filter your own water, out at the stream or while on the go. For many families in western Nepal, clean drinking water is not something that can be taken for granted. That is why we are supporting Viva con Agua Switzerland's drinking water project: providing drinking water, toilets, and hygiene training for villages and schools.
Achieved so far in Western Nepal: 100,000 people in village communities and 21,000 schoolchildren at 105 schools.

Customer reviews from Amazon

At first I was skeptical - then I was thrilled. The filter is brilliant; I tested it myself and had the water tested in a laboratory. […] The filter isn't the fastest, hence the gravity system. But a 500-liter capacity for such a small filter is really something. In my opinion, it is the best small filter I have come across so far.

Highly recommended; murky water clogs such filters after a few days, so pay attention to the filling technique as well. Otherwise, the filter works great, a total relief when passing water sources.

Very high quality; it's all about the idea, always with me on hikes, never thirsty again because there's always a trickle of water to be found along the way.
J. Delfs Verified purchase on Amazon

Fast delivery, the water filter works perfectly, but I bought an additional filter for the hose so the main filter doesn't get clogged with dirt too quickly. Unfortunately, there are no replacement filters available once the filter can no longer be cleaned; you have to buy a new one every time, which is a shame and gets expensive over time—maybe there will be replacement filters available at some point? One point deducted for that. Recommendation to buy from my side (yes), but everyone has to decide for themselves.

The product seems solid and well-made; however, the filtration function was obviously defective after very short use (tested a few times after unpacking), i.e., the water that was supposed to be filtered still looked dirty and by no means suitable for drinking. […] UPDATE: After I published my original review, the manufacturer contacted me directly. […] Without any discussion, we were offered a refund. […] Even though I still find the original defect regrettable and therefore cannot change my experience with the product itself, I would like to explicitly highlight the customer service.

As expected, a good purchase and explained in an easy-to-understand way.

Since I found out that our alpine waters contain pathogens that can cause diarrhea up to 2 weeks after drinking, I always have this thing with me.

Frequently Asked Questions
How long can the straw be stored?
Store in a dry place, away from direct sunlight. The straw should be replaced after two years at the latest, even if the maximum filter capacity has not yet been reached.
How many straws do I need?
One per person. Everyone drinks directly from their Straw, around 0.2 liters per minute, which is why it's difficult to share. Add one for the car or for a second emergency bag. Choose the number of people above: for two, we include an extra Straw for the car; for a family, we include two, and shipping is free for them.
From which water can I drink?
Suitable for freshwater from rain barrels, canisters, buckets, wells, streams, or lakes. Running water is preferable to stagnant water. Highly turbid water should be pre-filtered, for example through a cloth. Sea water and brackish water are not suitable. Also, avoid water sources near ship traffic, sewage treatment plants, or intensive agriculture.
The question, exactly as customers ask it
The answer. Short, concrete, without advertising language.
Does the Straw really filter viruses?
Yes. The straw works in two stages: electrically charged fibers bind viruses instead of just filtering them out. This is followed by an activated carbon block for taste.
What is not filtered?
Dissolved substances such as nitrate and salt. The Straw is also not designed to protect against radioactive substances or chemicals.
How long does the filter element last?
Up to 500 liters. This is the maximum value under optimal conditions. The cloudier or more heavily contaminated the water is, the faster the flow rate can decrease. If the flow is permanently and significantly reduced, the straw should be replaced.
Is there a replacement filter?
No. The device is used up after up to 500 liters. However, it is the cheapest entry into the range and requires no maintenance. If you want to change rather than replace: The Squeeze and Selfpress have replaceable filters.
How do I use the hose?
One end of the hose goes into the water, the other is connected to the filter. With a length of 70 cm, you can drink comfortably while standing or kneeling without having to bend down directly to the water.
What can I do if I have further questions?
