4 Pack Water Filter Straw - Water Purifying Device - Portable Personal Water Filtration Survival - for Emergency Kits Outdoor Activities and Hiking - Water Filter Camping Travel Survival Backpacking

Great value for money, won't know how they are until after our wild camping trip

These were purchased in the event of doomsday, or someone poisoning the waterhole. Thankfully not had to use them yet but useful piece of kit.

Excellent product, just as described, and fast shipping

I don’t know it works but it’s good to have it for the emergency

I was not expecting them to be so large however I am very happy with the purchase. Do I recommend yes, I do.

These products are a good value for the price. Their compact size is convenient, good quality material and functional. The water quality upon using was good. Fits perfectly in any emergency backpack.

Don’t know if they work. We took them to a third world country in case we needed them. We did not. But good to have!
