Gravity Fed Water Filtration System with Adjustable Tree Strap, 6L Large Gravity Bag with Filter Straw, Water Purifier Survival for Travel, Backpacking, and Emergency Preparedness (12L)

Great product.. don’t go out camping with out it

I made the mistake of purchasing 2 of these for our onsite and offsite emergency kits. Thank God I have enough common sense to make sure something works before I add it! First things first, even by their own documentation, these "100,000" gallon straws (according to Amazon page) are actually only good for *** 15 GALLONS *** in their life. They use a super cheap and tiny glued on activated charcoal filter that's supposed to be replaced after every 15 gallons. I went to see how much replacements costs out of curiosity, and guess what, THEY DON'T EVEN SELL ANY. Because they're just cheap glued on parts, I then checked if I could replace it, and then I realized that they weren't even glued on all the way, so the dirty contaminated water can just bypass it through the bottom! It says that you can use the remainder of the straw without it for a short time, but here's the thing, THAT'S THE ONLY ACTUAL FILTER! After the cheapo carbon "filter", the water enters a large chamber with the "hollow fiber membranes", these are just 1mm tubes that are stuffed in there not even taking up the width of the chamber so water just flows around them, but here's the kicker, they just took a bundle of these, bent them in the middle and shoved them in, SO WATER CAN'T EVEN ENTER THE ONES THAT ARE THERE! This means that the *only* water that you're getting through the system never even had a chance to go through the membranes! Any water you drink out of this has, at best, had the larger things filtered out by the tissue paper around the activated charcoal. In no way shape or form is this making any unsafe water safe! How are there so many high reviews for this? Is everyone just reviewing it without even reading the documentation or seeing if it's put together right?

I used this item on a fishing trip to filter the lake water for consumption, it worked great and nobody got sick yay!

Last yr I got pretty sick,having ingested lake water housing many Beavers. I got this Gravity filter, used it for everything. Dishes, cooking, and drinking. We all had a great time and didn’t have to call the Dr. after our canoe trip.
