Membrane Solutions S2 Detachable Water Filter Straw, 5-Pack

I am putting up for later but seems perfect

super handy to have when you go camping in the woods or even for safety if you go for a long hike. must have in your backpack.

Good price

Someone said their's leaked but I don't think mine did. It took quite a while (hours) to gravity filter 2 l of water. I couldn't squeeze my bag for fear of popping it. Even then I would have to squeeze really hard. There is a little charcoal element in there but it's very small. I don't see it being effective to 10,000 gallons or whatever this claims. Otherwise it does what it's supposed to do but slowly.

I have them in my emergency back pack, it has a good wrap i hope it last

No complaints at all well packaged!!

Excellent product and shipping

Just to be prepared. Knowing that we will be able to have drinkable water in times of emergency is such relief.

Passt alles!

Straw is working perfectly. It can be fixed on to Mai Dubai’s water bottle. Remember to remove the cap locking ring on bottle neck before fixing the filter straw. Water flow is not too much but it’s more than enough to survive. Very useful gadget to have camping, trekking and travelling.

Love these, we take these every year back country camping, drinking from lakes and rivers, clean and purify water so well. Water tastes better than from a tap!

Good filter

Works great 😊 I would recommend this product!
