Waterdrop Water Filter Straw, Camping Water Filtration System, Water Purifier Survival Outdoor Drinking Water Purifier for Travel, Backpacking and Emergency Preparedness, 0.1 Micron (Blue), Pack of 2

I wish I had pictures for when I went camping in MN. These are the BEST filters to have. Buy the gravity bag too. You wont regret it. The water in Minnesota is almost black from the tannins (rotting leaves). Filtering the water is harsh on filters but having a steady supply of water on hand is nice when cooking and cleaning. Having these filters on hand means you can constantly have a clean source of water. The filter compound filters all particles and micro bacteria except for viruses. Not unless your in an area with a commonly known contaminated water source I would not use these. The flow of water can be a little slow but 1Cup of water is approximately given within 1 minute. Tip: When using the filter with the gravity fed bag. The lowest point of flow is the strongest but keep in mind DO NOT leave the filter dangling below the bag when not using or the water will continually flow and drain even with the cap on. When not using place the filter above the bag and hook in between the bag straps.

Great for emergency, adequat Amount of water filtration. Very happy with it

As a long time LifeStraw user I have to come to terms that this Waterdrop Straw Filter is faster, and cheaper than the LifeStraw. As compared to the flow rate, this thing blows the LifeStraw away. I find the material quality to be just as good as the LifeStraw, and at a lower cost. When it comes to straw filters, I stopped buying everything else and only buy Waterdrop - at this time anyway.

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. works as described. I can fill a bottle with tap water, screw this on, and purify as I drink.

We traveled to Italy with this filter system. Water tasted awesome. Did not have to buy bottled water. Packed in our suit case for the flight. Wouldn't go anywhere without it!

No foul taste, quick and easy to use

These work great, we always bring extras

Wertvolle Dienste geleistet bei unseren offroad- Touren, reist jetzt somit als Nachfüllpackung nach Marokko mit.

Super. Usato in Groenlandia

Perfecto, encaja con la descripción. Ocupa muy poco en la mochila. Ideal si vas descampada o excursión
