Review: Camping essential - The bladder can hold about 5L. Ive used this many times on camping trips. Not sure how many litres the filter can take but so far done about 4 trips with it and the water tastes just list it did when the filter was brand new. The water taste is a bit like water from a brita filter. It tastes clean and removes all the nasty stuff that you don't see with a naked eye. Normally I would buy 5 litre jugs of water and carry it to camp site but that's no longer required. This filter is a life saver and doesn't take much space in your backpack. You can break it up into bits to make it fit better in your backpack if you like.
Review: I think it is a great thing to have. - I bought this so that I didnt have to carry lots of water. But I keep reading that people can still become ill even with a filter so perhaps you also want chemical tables to purify your water. The product itself is brilliant, light and probably just what you want. Just check on the plastic bottle screw top size that you want to attach it to as smaller bottles dont fit and nor do large bottles but getting the correct bottle is as easy as buying what ever drink from the co-op, drinking it and reusing that bottle. I have only tested it in the kitchen, it filters quite fast and the plastic pouch seems quality. It all compresses down and can be easily stored in a ruck sack. I have used one properly in the past to filter canal water which I then boilded. The water was clear and tasted "ok". The product (the filter) itself can be used stand alone without the pouch and becomes a straw which I would be happy to use on a hill stream while camping as long as it isnt regularly used by other people going to the loo nearby - its human waste contaminating the water that can make you ill rather than the odd sheep. I read a report that human waste was the reason people using filters like this became ill in Scotland (not animal waste). So from now on in poplular walking sites I'd use either a tablet or boil in addition to this filter. Out in the sticks with normal river water I think it'd be fine with just the filter as long as you're not near a farm - but read up on the risks first.

**Q: how long does this product last? 1 day? 1 month?**
A: I  used it for the first time this weekend. On a backpacking trip. I thought it was useful to have in addition to a filter pump to bring water back to Camp. It seemed well-made, how long it will last Would probably depend on how dirty the water is that you put through it ,if you clean it consistently and if you were careful not to abuse it. But I will get $20 worth of use out of it for sure.  I expect it to last me for multiple trips.

**Q: Does it come with the bag?**
A: Hi Mike,

Thank you for your interest in our Water Filter Straw. Yes, the item comes with two bags.  One is the blue gravity water bag which is used to fill with the raw water, another is white used to fill with the filtered water. They are connected via the straw to filter the water for drinking.

### ⭐⭐⭐⭐⭐ Worked well and fast, with good taste
*by R***N on 3 June 2024*

• Filled a 1.5L bottle in about 2 minutes. • Water was crystal clear when filtered, no dirt visible. • Water tasted good, however that might be dependent on the source. • Simple to set up. • Slightly large to pack in rucksack but not huge and might find a more compact way to pack. • Lightweight. • Got it at £29, incredible value for health.
