Squeezable Water Pouches with Water Filter Straw(1+6) | Survival Water Purifier Kit, Portable Water Purifier for Backpacking, Camping, Hiking and Emergency Preparedness

A great gift Christmas for mountain climbers.

I love this set up. I’ve also got the Grale cup that you can just press but it’s heavy compared to this water system. I’ve used just one for 3 people to fill bladders and Nalgenes. Takes some time but not a lot. Easy to use.

Edit: Upgraded rating to four stars. Seller offered full refund because I couldn't use the filter as designed. Great seller and follow-up. I bought this for travel use based on filter specs, and I believe it will work. But the supplied bag and other items have questionable design. I expect to hang the bag and filter over a water bottle and let it work unattended. There is no way to hang the bag as designed. The side hole and carabiner are in the wrong position and that location makes no sense. So I made an end hanger loop out of heavy fish line through two carefully punched holes in one layer of the end as shown. Do not punch through the center area as shown by the red dot. That goes through the actual bag area and then it won't hold water. (Ask me how I know. One bag to trash.) The filter is nice and compact and processed one bag of water in only three or four minutes. The durability of the bag remains to be seen as it is pretty lightweight. One carabiner was bent and barely useful. I don't need the two push-pull caps, but they are so difficult to use. I could only remove the clear cover cap with pliers. Pulling the movable cap up requires considerable force. I regard this as a useful product if you consider the design and your needs, and decent for the price. I didn't want to invest in a powered or more elegant unit for my modest use. Average rating.

Got these for a backpack trip where we knew we had to find water source. Filter system worked great. Liked that they came with clips to hook onto your packs. Light weight and easy to pack!

This is a good item to have just in case something goes a mist and fresh water is not available.

Filter itself works well but is a little slow. Thus you have to add pressure to the bags to fill your bottle in a timely manner. Both bags came apart near the neck within two days of use. Thankfully, we came to a resupply store on day 3 so I could purchase a new bag.

good backup system

Very convenient. Order two sets so I could have 3 purified containers with one as the "dirty" water input. Took less than a minute per container. Takes up less space than a bottle of water in your backpack.

J’ai acheté ce produit pour faire du canot camping. Ça fait exactement ce dont je voulais ce qui veut donc dire ne pas tomber malade avec de l’eau. Lorsque nous sommes loin dans le bois, il est parfois difficile d’avoir de l’eau potable et ses membranes ont fait exactement ce dont je m’attendais comme utilisation..

Very helpful for carrying water in the wood

It worked but 1 of the bags broke right away... kind of expected but also kind of a bummer.

Easier lighter cheaper than a hand pump, I can afford to put one in each emergency kit and still money left for first aid or whatever.

They look good - haven't used them yet.
