Gravity Water Filter System w/ 2-Gal Bag & 0.1-Micron Water Filter Straw, Gravity-Fed Water Filtration System Water Purifier Survival for Camping, Backpacking, Hiking & Emergency Preparedness

Works great. Short learning curve to get used to filling the large bladder and using the filter with smaller pouches. Ended up buying additional pouches (which came with another filter). Filters were easy to clean. This is great for larger group camping where you don't need to filter water fast. We just got in the habit of filling the bladder at night so we'd have fresh water in the morning, then fill it again so it would filter more throughout the day. Another bit of advice, be sure to store it in a manner so it can thoroughly dry. I ended up 3D printing some hangers, similar to what Camelback used to sell to air out their bladder packs.

Great product! Good price!! Bought for camping and bug out supplies!!

Works great. A real life saver.

Works great

Can't find anything wrong with this. We used it on a cruise where we did not have a drink package. The water on the ship is potable but did not taste or smell good. Before the cruise, I followed the instructions for first use. It was messy because I hadn't tightened one piece well. Once I figured how much to tighten everything, no leaks. My husband chose to drink directly from the straw, but I preferred to squeeze out the water into a container. Very easy. You can hold it upside down and water will drip from the sip part of the straw or you can squeeze to hasten the flow. This is going to go with me on all trips now. Light, takes up little space in my suitcase, and does the job. We aren't brave enough to try this on dirty water.

They haven’t been tested yet K

Lo compré por las bolsas, no he usado el filtro, pero las bolsas ya las usé, muy buena calidad y te evitan el peso de los envases comunes.

Almost one year later. One of the filter pouches sprung a leak at the seam around the top opening. Glad I brought two of the pouches on my trip otherwise I’d be SOL.
