Product description
Drinkable water from almost any source, without power, without boiling
When the mains go down, water is the first thing a household runs short of. The AQUA-X1 is a hollow fibre filter straw you keep on a shelf until the day you need it. No batteries, no charging, no chemicals, no waiting for a kettle. You drink straight from the source, or filter into a bottle for the rest of the family.
Why households keep one per person
- Up to 1500 litres per filter. That is years of drinking water for one person in an emergency, from a single unit.
- 0.1 micron hollow fibre membrane. Mechanical filtration, so there is nothing to run out of and nothing to replace.
- No power and no heat required. It works in a blackout, in a car, on a walk, and in a flooded street.
- Weighs under 100 grams. Small enough for a coat pocket, a glovebox, a school bag or a bug-out bag.
- Stores for years unopened. Buy it once, put it in the cupboard, forget about it until it matters.
- Three ways to drink. Sip direct from the source, screw onto a standard bottle, or squeeze from the included reservoir.

How it works
- Find water. A stream, a rain butt, a tap running brown, a puddle, a pond.
- Fill or dip. Fill the reservoir, or put the straw straight into the water.
- Draw. Your own suction pulls the water through the membrane.
- Drink. Clean water comes out the other end. Backflush with the syringe when the flow slows.
Three stages, one pass
- Pre-filter. Sediment, grit and visible debris are held back before they reach the membrane.
- Hollow fibre membrane. Thousands of 0.1 micron channels let water through and hold back anything larger.
- Carbon stage. Reduces odour, taste and organic residue, so the water is something you will actually drink.
What it is designed to hold back
- Bacteria including E. coli, salmonella and cholera
- Parasites and protozoa including giardia and cryptosporidium
- Microplastics down to the membrane's pore size
- Sediment, silt and sand
- Cloudiness and visible particles
- Organic matter that causes bad taste and smell
A mechanical filter of this type does not remove dissolved salt, heavy metals or viruses. It is built for the water you are realistically going to face in a European household emergency: a contaminated mains supply, a flooded street, standing water, a stream.

Questions people ask
Is this better than boiling?
It is faster and it works when you have no power and no gas. Boiling kills organisms but leaves the sediment, the cloudiness and the taste. This removes those too, in one pass, with no fuel.
How long does one filter last?
Up to 1500 litres, which is roughly two litres a day for two years for one person.
How long can I store it?
Unopened and dry, five years or more. Once used, keep it from freezing and backflush it before storing.
How many does my household need?
One per person is the sensible baseline, because in an emergency people separate. Most families take the five pack for the house and keep spares in the cars.
Can children use it?
Yes. It takes an ordinary sip, no more effort than a thick milkshake straw. Supervise younger children the first time.
I live in a city. Is this relevant to me?
Cities are where mains supply fails hardest, because there is no well and no stream in the garden. Boil notices, burst mains, flooding and grid failures all end with the same problem.
How do I maintain it?
Backflush with the syringe when flow slows. That is the whole maintenance routine.
What if I want to return it?
60 days, no argument.

Three ways to drink
How to use it
No power, no batteries, no chemicals. Pick whichever suits the moment.

Drink straight from the source
Put the straw into a stream, a rain butt or a filled glass and sip. Nothing to set up.

Screw it onto a bottle
Fits any standard 28mm bottle thread, so a supermarket bottle becomes a filter you can carry.

Hang the bag and let gravity work
Connect the 6L bag, hang it from a branch and let it run into any bottle. Hands free, enough for the whole household.
What is in the box
An entire filtration system in your backpack
Everything is included. Each part works with the others to source, filter and store clean water in any situation.
Tap a plus to see what each part does.

Carabiner clip
Clips the straw to a belt loop, a rucksack strap or the outside of a go-bag, so it travels where you do instead of at the bottom of a drawer.
AQUA-X1 filter straw
The four-stage cartridge. A 0.1 micron hollow fibre membrane, activated carbon and two pre-filter pads, good for up to 1500 litres with nothing to charge or replace.
Backflush syringe
When the flow slows, fill the syringe with clean water and push it back through the straw. Thirty seconds and the filter runs like new. This is why there is no cartridge to buy.
Collapsible pouch
Scoop it full at the water source and drink at your own pace, or screw the straw on and squeeze. Folds flat to nothing when empty.
Extension drinking tube
Push it onto the straw to reach water you cannot kneel over: a deep container, a rain butt, a puddle under a car. Drink without lying down in the mud.
Instruction leaflet

FAQs
Got questions? We have answers.
Why do I need this when I can just boil water?
Boiling needs a heat source. In the emergencies this is built for, a blackout, a burst main, a flood, the gas and the power are usually the first things to go. The AQUA-X1 works with nothing but your own breath.
Boiling also only kills organisms. It leaves the sediment, the cloudiness and the taste behind. The four-stage cartridge takes those out in the same pass.
What does the filtration actually remove?
The 0.1 micron hollow fibre membrane removes 99.999999% of bacteria such as E. coli and salmonella, along with microplastics, sediment and cloudiness. The activated carbon stage takes out chlorine and the taste and smell that come with standing or treated water.
It is not designed for salt water or heavy chemical contamination. For those you need distillation or a dedicated purifier.
How long does one filter last?
Up to 1500 litres. For a single person drinking two litres a day that is well over two years of continuous use, so in a short emergency you are nowhere near the limit.
There is no cartridge to buy and no schedule to keep. When flow slows, backflush it with clean water and it recovers.
How many should I buy for my household?
One per person is the sensible baseline, because in a real emergency people are rarely all in the same place. Most households take the 5-Pack for the home and keep the spares in the cars and the go-bags.
I live in a flat in the city. Do I really need this?
City flats are the case this is built for, not the exception.
Mains pressure only carries water so far up on its own. In Berlin that is roughly 22 metres, about the roof height of an ordinary block. Everything above that runs on electric pressure booster pumps in the basement.
During the four-day power cut in Berlin in January 2026 the water kept flowing lower down, but from the sixth floor it was a trickle and from the seventh barely a drop. People living higher up carried water upstairs from neighbours in buckets.
If you live above the fifth floor, a blackout is a water problem for you before it is one for anyone else in the building.
Does it need power, batteries or chemicals?
None of the three. There is nothing to charge, nothing to replace and no tablets to add. It is a sealed mechanical filter, which is exactly why it still works when everything else has stopped.
How long can I store it unused?
Five years or more, unopened and dry. Once it has been used, keep it from freezing and backflush it before you put it away. Freezing is the one thing that damages a wet membrane.
Can children use it?
Yes. It takes an ordinary sip, about the effort of a thick milkshake through a straw. Supervise younger children the first time so they learn to breathe out through it to clear the line.
How quickly will it ship, and what if I want to return it?
Orders are processed within one working day and delivery across the EU usually takes 3 to 7 working days. Tracking is emailed as soon as the parcel leaves.
If it is not for you, send it back within 60 days for a full refund. No argument and no restocking fee.

I bought the 5-pack because one filter for an entire family did not feel like much of a plan. We now have one in every emergency backpack and a spare in the car. Hopefully we never need them, but I genuinely sleep better knowing we have another option if bottled water becomes unavailable.
My husband originally thought this was unnecessary. Then our neighbourhood had a water interruption and the large bottles disappeared from the supermarket within hours. We did not need the filter that day, but it made us realise how dependent we were. It now stays beside our first-aid kit and torches.

Ordered the 10-pack for our household, both cars and my parents. Giving two to my parents was probably the most important part for me. They cannot easily carry heavy packs of bottled water, and I wanted them to have something they could keep at home.

Originally bought it for emergencies but tested it on a hiking weekend using clear water from a flowing freshwater stream. It took slightly more suction than a normal straw, but the water came through crystal clear and without the earthy taste I expected. Very easy once you understand how it works.
We live in a small apartment and cannot store huge amounts of bottled water. This takes almost no space. We still keep bottled water because that is what we would use first, but now we have a backup if those bottles run out.

Bought the 5-pack for our family. Each person has one, and everyone knows where it is kept. The best part was actually sitting down with the children and discussing what we would do during a longer outage. We finally have a plan instead of just saying we should prepare someday.
With all the discussions about energy security in Europe, I wanted to make our household a little less dependent. This does not solve every emergency, of course, but clean water is one of the first things a family needs. Small purchase, big peace of mind.
The filter itself works well and feels sturdier than expected. The first few pulls required more suction than I imagined, so there is a small learning curve. After the water started flowing it became much easier. I would recommend testing it before putting it into an emergency bag.
We chose the 10-pack and divided it between our house and our daughter’s family. It is reassuring to know that both households have the same equipment and know how to use it. Nobody has to come looking for us if something happens.
I bought the full system with the additional water bag, thermal blankets, solar-powered power bank, emergency radio and lights that work without electricity. For years I had random supplies in different cupboards. Now everything is together, labelled and ready.
Bought it for camping and ended up ordering another one for our emergency supplies. Camping was actually the perfect way to practise because nobody was stressed or in a hurry. Now both my husband and I know how to connect, use and clean it.
Five filters, five emergency backpacks. Simple. I like that there is no battery to charge and no complicated electronic part that can fail. We packed them away dry and will check the bags once a year.
The filter works, but drinking through it requires more suction than I expected. The water came through clear and the product feels sturdy, although the instructions could explain the first use and cleaning process better. I will keep it in our emergency kit, but it was not quite as effortless as the advertising made it appear.
My mother worries whenever she sees news about outages or supply problems. I showed her our stored water and this filter as the backup. She finally said, “Good, you have thought about the children.” It made her calmer, and honestly it made me calmer too.
After seeing what happened during the major blackout in Spain and Portugal, I stopped assuming essential services could never be disrupted in Europe. Trains stopped, communications failed and ordinary things suddenly became difficult. I bought this because I wanted at least one simple water backup that did not need electricity.
We ordered the 10-pack for five people, giving everyone one filter plus a backup. I do not want our entire family water plan to depend on one small item being in the correct bag at the correct moment.
The filtration seems good and the water came through visibly clearer, but the flow was slower than I expected. It is fine for drinking, although filtering larger quantities takes patience. I will keep it for emergencies, but I would have preferred a bigger water bag and faster instructions for first-time use.
I gave one to each of my adult children. They were not exactly excited about receiving water filters, but all of them kept one. My son even moved his into the family camping bag. Not a glamorous gift, but possibly the most practical one I have given them.
The 5-pack was perfect for our family of four. Everyone has one and the extra filter stays with the water bag. I labelled the components so the children can immediately see what belongs together.
Reading constant news about energy, infrastructure and emergencies was making me anxious. Buying this did not remove every risk, but it allowed me to turn some of that worry into a practical action. I feel less helpless now.
Compact, simple and apparently well made. My only criticism is that the first draw requires fairly strong suction. Adults should be fine, but for a young child I would use the squeeze bag to fill a cup or bottle. Apart from that, it does exactly what I wanted.
Ours stays permanently in the caravan. It is useful for remote trips and also gives us a backup if a campsite ever has problems with its drinking water. It packs so flat that there is no reason not to bring it.
I was worried the filtered water would have a strong plastic or chemical taste. We tested it while hiking and the taste was surprisingly neutral. The water looked clear and there was no unpleasant smell. Just remember to clean it and let it dry properly afterwards.
When the German civil-protection office tells households to prepare for emergencies, I think it is sensible to listen. We already had food, a radio and bottled water, but no longer-term water backup. This filled the biggest gap in our supplies.
We ordered the 5-pack even though there are only three of us. One small filter can be misplaced or left in the wrong car. Having two backups means our plan does not fail because of one forgotten backpack.
My order did not arrive until I contacted customer support. Apparently something had gone wrong with the carrier. Support did help and arranged for the package to reach me, but it took almost three weeks in total. The filters themselves look fine, but the delivery experience was frustrating.
We still store bottled drinking water. This filter does not replace that. It gives us another option if our stored water runs out and the shops are empty. Once my husband understood that, he agreed it was a very sensible purchase.
After putting it off for years, I ordered the full system with the additional water bag, thermal blankets, solar-powered power bank, emergency radio and powerless lights. Everything is now stored in two clearly marked boxes. My wife also knows exactly where to find it if I am away.
The 10-pack initially sounded excessive. Then we put two at home, one in each car, one in every emergency bag and gave the remaining filters to the grandparents. Ten suddenly felt like the correct number.
Purchased as emergency equipment, but it has already travelled with us on two road trips. It takes less room than an extra water bottle and gives me peace of mind when we drive through remote areas.
We once had a boil-water notice and discovered we had only a few small bottles at home. By the time I reached the supermarket, most of the shelves were empty. That experience stayed with me. We now have stored water plus these filters as our backup.
The filter is compact and the different connection options are useful. Direct drinking worked, but I found the water bag more practical for filling cups. Four stars because the instructions could explain the first setup and cleaning process more clearly.
People think a water filter is only for someone living beside a forest or river. We live in a city, which is precisely why I wanted one. We depend completely on public infrastructure and shops. This gives us at least one alternative.
We tested it with clear flowing freshwater during a camping weekend. The water coming through looked crystal clear and tasted much better than expected. Most importantly, we now know how everything works before a real emergency happens.
Bought the 10-pack for my wife, children and grandchildren. Some stay at home and the rest are in the vehicles. I would rather prepare quietly now than stand in a crowded shop searching for the last bottles of water later.
The water bag is what makes this practical for a family. Instead of having everyone drink directly from the source, I can filter water into separate cups and bottles. Much easier with children.
No electricity, battery, app or charging cable. Exactly what I wanted. Mine stays in the van beside a first-aid kit, torch and warm clothes.
European authorities have increasingly encouraged households to be capable of managing the first days of a crisis. We had some food and torches but had completely overlooked water. This was an easy way to make our emergency cupboard more complete.
Bought the 5-pack so we could keep filters at home, in both cars and with my parents. They are compact, feel well made and give us extra peace of mind. One of the water bags was difficult to attach at first, which is why I removed one star, but everything worked correctly after I tightened it properly.
I initially thought the flow was too slow. Then I checked the connections and started again properly. Much better. Water has to pass through the filter, so naturally it will not flow like an open sports bottle. Once I understood that, it made sense.
Four friends and I divided a 5-pack for our hiking group. We tested them once together and were all surprised by how small they were. Mine now lives permanently in my backpack.
Overall I am happy with it. It is small, practical and does not need power. I removed one star because I expected the larger bag to be included in my option and had to order it separately. Check exactly what comes with your package before buying.
We hike with two dogs and carry a lot of water. The filter gives us a backup if a walk takes much longer than planned. We can use the bag to filter water into a separate bowl instead of letting the dogs drink directly from unknown water.
My daughter studies several hours away from home. I cannot immediately help her if there is a serious outage, which bothers me more than I admit. I sent her one with a torch and power bank. She laughed at first but keeps the kit beside her front door.
The 10-pack covered three generations of our family. We spent one Sunday demonstrating everything and deciding where each filter would be stored. The real benefit was knowing the whole family had discussed a plan instead of assuming someone else would take care of it.
Small enough that I actually carry it. A lot of emergency gear gets left at home because it is bulky or heavy. This has been in my backpack for months and I barely notice it.
I wanted one complete emergency setup, so I bought the filter and extra water bag together with thermal blankets, a solar-powered power bank, emergency radio and lights that do not depend on mains electricity. It covers the things I worried about most: water, warmth, information, light and limited power.
A storm once left our village without electricity for most of the day. The water continued working, but it showed us how quickly normal life can become uncertain. With the ongoing energy concerns in Europe, having a water filter that works without power feels like sensible preparation rather than panic.
There are four of us, so we chose the 5-pack and kept one unused as a backup. We practised with one near a freshwater stream so everyone could see how it worked. The children were amazed by how clear the water looked afterwards.
Before buying this, I kept adding bottled water to the shopping list, using it, forgetting to replace it and worrying again. We still rotate a reasonable supply of bottled water, but now there is a longer-term backup in the cupboard. The biggest benefit is that I can stop thinking about the problem every week.
