Waterdrop Portable Water Filter Straw, Camping Water Filter | Survival Water Purifier, 0.1 Micron Filtration for Hiking, Travel & Emergency Preparedness, Survival Gear, 2 Pack

Been using them since they came on the market for camping. Great and works. I extended them with tubing so not to get down so far with my senior age now a days.

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.

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

Haven't used them yet waiting on the apocalypse

Really big straws I thought they be small but there not . There very thick straws I was not expecting that but they do in emergency .

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

Schicke ich regelmäßig nach Kuba... an Familien die zuerst das System erhielten und nun ihr Wasser damit filtern. Seit dem (3 Jahre nun....) gibt es keine Magenbeschwerden mehr.

Ok top

Non vedevo l'ora di riceverlo e ha superato ogni aspettativa! 😍 Il filtro è leggero, compatto, intuitivo da usare e... geniale: puoi riempire la bottiglia pieghevole inclusa, sottile e dotata di moschettone, e bere direttamente come se fosse una cannuccia 💦 Non solo è pratico e ben pensato, ma arriva senza bisogno di acquistare altri accessori a parte. Non vedo l'ora di testarlo sul campo, ma già merita una recensione per come è stato progettato. Grazie a chi l'ha ideato: è uno di quegli oggetti da portare con sé ovunque, con fiducia 🩵

Efectividad, facilidad y seguridad en el uso, imprescindible tenerlo en casa

Impeccable
