Review: Well thought out !!! - Doesn't suck sediment in to drinking 🚰 tube 👍🤠 I am a former soldier 🪖 and qualified plumbing and heating engineer and I like this water 💦 bladder because you can allow sediment to settle for an hour and then suck cleaner water 💦 into the tube without 🚫 sucking up any contaminates that have settled in the bottom of the water collection bag !!! Floating 🛟 contaminants can be over flowed off the top of the bag leaving the cleanest water to be drawn from above the bottom of bag but below 👇 the surface !!! This not only gives you the cleanest water 💦 without filtering ' but it also stops the worst of any sediments from blocking the tube or fittings 👍😊 Well done 👍✅ It's also very lite and easy to use ' and I haven't noticed any plastic taste from the water 💦 collection bag or tube 👍 Obviously water 💦 for drinking 🚰 should always be treated or boiled to make it sterile ' but this is the best design I have seen on the market 👍😊
Review: Love the water purifier bag - I really liked this water purification bag, with the line attachment being on the side, allows for any settlement that gets picked up to settle on the bottom and not to go through the filter. The hose, the clamp, the bag and the straps all worked very well. The only thing is that it doesn’t come with a second hose so once you add the water purification filter (bought separately) another hose is not necessary, but works well in order to fill up bottles containers, pots, bowls, and whatever else that you need the water for. I definitely found it affordable, functional and would highly recommend it for any back country camping. Or any place requiring clean water. 👍😁

### ⭐⭐⭐⭐ Works, but difficult to use due to small clip size
*by J***E on 27 April 2024*

The water filter system works well. Like its design. But a issue is that the rings at the top of the water bag, which you are supposed to attach to the hooks of the strap, the size of these rings are too small. When you are carrying a 6kg load and trying to attach it to a tree branch, you don't have the energy to play around with hooking on such a small ring. I am going to buy some carabiners separately, to make it easier on myself.
