Good, affordable filter for small scale, portable filtering of clear water
This water filter works in a variety of ways, including as a straw or an inline filer with pump. Thankfully bought and brought along as a backup, it got a family of 3 through a canoe trip when our regular filer let us down. Filtering enough water took time and patience, but worked fine, in that no one got Beaver Fever! It woks better as a straw, to filter clear water for one person, especially on a day trip, paired with a basic mug. Well worth the money, as long as you don't expect to filter a lot of water. It arrived well packages and very quickly.
Works but some nuances
Use the Waterdrop Filter Straw while on a backcountry hike in the Smokey Mountains and it works pretty well! There are couple of annoying issues, first using it as a gravity filter from source container to another doesn't really work. In the picture I had to squeeze the water source bottle in order for it to filter through. When bottles like this I had to make sure the collection bottle was squeezed in to remove as much as air as possible to get water to filter through. Once air and water had passed through I would again have to squeeze and remove air to get more water to pass through. Maybe adding vent hole to collection bottle somehow would eliminate this air pressure issue.Secondly, if you're using bottles like this it's a good idea to remove the remaining plastic ring that remains after taking the cap off. Found this little ring prevented from creating a tight seal and water would leak on the supply side.Using the filter straw as a straw worked great whether attached to bottle or directly in stream. For drinking directly from stream would be nice to have a bit of tubing to stick into water source without having to bend over, especially when you're wearing a heavy backpack.
great product, great price
works great. I put fine ash in hot water and then filtered it through this and it came out crystal clear and tasted good after cooking. I've used it on a handful of outings in the woods on some less than ideal looking water and haven't gotten sick or had complaints about flavor from friends. great value
Paille filtrante
Difficult to use to get higher volumes. As a straw it is ok.
