Cleans the water well. However, it requires the power of a hunch.

A handy bottle for hiking. The filtration time clearly increases with the number of filtration times.

I expected a lot from this. In the beginning, the pumping technique felt good and (the filter) worked admirably. I was a little disappointed, as the length of the filtering time increased and increased sharply, even though there were only a few dozen tanks of filtered water behind. In the end, the time stretched to a couple of minutes, and one would think that the lake waters of southern Finland would not clog the filter so quickly. I was ready to accept the first filter as a test piece and decided to buy a new one, but I was surprised when I couldn't find them in any of the brick and mortar stores near me. I gave up and got another different device. - Locked

A well-filtered bottle that is quite small in size. Sometimes it's a bit heavy.

A smart device and reduces the load to be transported. Changes very quickly very slowly. If you squeeze the filter dry by pumping air after each use, it will be easier to squeeze out the water.

very practical and effective product which reduces the volume of water to carry on a hike. remember to slightly unscrew the lid before pressing otherwise you will, like me, have a lot of trouble the first time...

A little bit of gravity comes into play and you get quickly squeezed clean water that is safe to drink. Filters are saved if you don't filter tap water at all, and you have to remember that blue-green algae-contaminated water should not be used for drinking or cooking, even if it is filtered. This filter saves you from unnecessary ballast when you don't have to carry so much water with you at once. A small price to pay for not having an upset stomach and the need to evacuate the wilderness.

Light and handy to carry around. It makes it a lot easier on the trip when you don't have to carry water with you. Works!

I tested the product with central European tap water and for that purpose the product worked well. You can estimate the average number of times of use, but it makes you wonder, how do you know when it's time to change the filter?
