Let’s make traveling more sustainable

Save money and prevent plastic bottle pollution. With the Flo-Bro One water filter you can easily filter water from any freshwater source – anywhere in the world!

Our goal has always been to develop an easy-to-use water filter, without electricity and expensive cartridges. The core of Flo-Bro One filters viruses, bacteria, and protozoa. Additionally, you can use the add-on Carbon+Zeolite capsule to reduce heavy metals, chemicals, and taste.

We designed Flo-Bro One with the feature to attach PET bottles, because we want to encourage people to reuse their plastic bottles, and prevent plastic pollution.

Thanks to the universal design, you can filter water from any freshwater source. No matter if you are indoors of outdoors, Flo-Bro One got you covered.

Benefits of bringing Flo-Bro One on your next trip:

 Flo-Bro One vs. Dirty Water

We all love traveling. It’s one of those things you can’t get enough of and wish you can do as often as possible. We are not going to give you all the advantages of traveling, nor tell you why it’s great – you already know this. Instead, we would like to talk about the other side of traveling:

  • It costs money
  • It increases your carbon footprint on the Earth

Now, what if we would tell you that Flo-Bro One could reduce both of these effects? Let us give you a few examples:

Thanks to its light weight and compact size, you can take Flo-Bro One anywhere you want.

Exactly 130 grams (4.6 oz.) and 16 cm (6.3 in) is the space you need to bring this powerful water filter on your next journey.

And it floats.

The universal design of Flo-Bro One allows you to filter water from any freshwater source. Attach it to your tap or shower hose inside your room, or go outside and collect water from a river or lake. No matter where you are, you always have access to clean drinking water.

This technology makes expensive replaceable cartridges a thing of the past and brings reusability to the present. Clean your water filter to extend the lifetime to several years and thousands litres of water.

At Flo-Bro we believe that simple and durably designed products are the core of sustainable development. That vision led us to the creation of a simple cleaning procedure, which enhances the lifetime of the filter. This eliminates the need for expensive and often polluting, replacer cartridges.

Flush: Open inlet 1 and 2, and connect Flo-Bro One to a hose. By opening the water tap, the water flows through the filter, taking most of the build-up dirt with it, and thereby extending the lifetime.

When you notice reduced performance (water flow gets slower), then you should backwash the filter.

Backwash: Connect a PET bottle to the outlet and start filtering. Once your bottle is half filled, screw it tightly onto the outlet. Then disconnect Flo-Bro from the hose and open both inlets. Turn the bottle upside down and squeeze it. This forces water to flow backwards through the membrane, loosening accumulated dirt and flushing it back.


Did you know that a million plastic bottles are bought around the world, every minute? Once used, they end up in overfilled trashcans, forgotten in the forests, or washed up on beaches.

Say goodbye to single-use plastic bottles, and start refilling with Flo-Bro One. Thanks to the universal screw-thread, you can reuse any PET bottle by simple screwing it to the outlet.

If you travel around with your own water bottle, you can refill it just as easily with safe drinking water.

To purchase the add-ons, simply add the amount to your pledge and we will send the add-on together with your order. After the Kickstarter campaign, it will also be possible to order additional Carbon+Zeolite capsules at our website.

  • Add +$12 to your pledge for the add-on hose
  • Add +$5 to your pledge for the add-on Carbon+Zeolite capsule (25pc)

Ultrafiltration membranes

Flo-Bro One utilizes ultrafiltration membranes. A technology where the pore size is 10x smaller than microfiltration, which is used in straw or pen type filters. These filters are not capable of filtering dangerous viruses from the water.

The water filter is aimed mostly at travelers who stay in the civilization and can get access to running water – a shower or tap, so the filter takes advantage of this and can be easily fitted to them. The inspiration to make Flo-Bro One this way came during our journey in South East Asia. No need for pumping or sucking, let water pressure do the work.

Additionally, we introduced the option to filter water from a river or lake, to provide travelers with one single solution to always have access to clean drinking water, no matter what situation they are in.

Even though Flo-Bro One is designed with travelers in mind, the water filter is also a valuable addition to every emergency kit. Thanks to the durable and universal design, you can be assured that you have access to safe drinking water, no matter what happens.

With Flo-Bro One you are always able to provide your family and friends with safe drinking water.

A collection of the Flo-Bro evolution. It all started with that long clumsy device to test the functionality. Along the way we improved on the design, durability, and the add-ons were included.

Join our mission of making drinking water more accessible worldwide, and help spread the word:


We are Radek & Robin, two guys who, just like you, love to travel. During our 6-month journey through South-East Asia we were shocked by the amount of plastic polluting the jungle and beaches, so we took it upon us to come up with a solution. This is where the idea of Flo-Bro One was born: an easy-to-use water filter for travelers, which doesn’t need expensive cartridges.

Radek graduated with a Master’s degree in chemical engineering, specialized on separation technologies. He then worked several years in the R&D department of a global company that produces industrial filtration systems for municipalities, factories, breweries and others. He downscaled this technology to the size of Flo-Bro One, so you can carry it anywhere in the world.

For over a year we have been developing and testing several prototypes of Flo-Bro One. We are super thrilled to share our solution with you! A portable, affordable, and durable water filter for travelers that provides a solid alternative to bottled water. Together we can make traveling more sustainable, and fight plastic bottle pollution.

Risks and challenges

After creating five different working prototypes, we are confident to start producing on a larger scale. All key suppliers have been identified and are ready to start shipping the materials once we give them the “go-ahead”.
The first step is to produce the mold, in which the outer parts of Flo-Bro One are pressed. Once that is ready, the Flo-Bro team will produce the first batch of water filters, nothing will be outsourced at this point. We made the decision to do it ourselves to be 100% sure that we set up a smooth and safe production line.

The second step is to obtain the right certification. Our current prototypes meet the criteria that are needed for the certification, so we expect this to be a smooth process.

Even though we have taken all risks and challenges into account, delays might occur due to unforeseen circumstances. Nevertheless, our top priority is to start shipping in April!
