Membrane Solutions Straw Water Filter, Survival Filtration Portable Gear, Emergency Preparedness, Supply for Drinking Hiking Camping Travel Hunting Fishing Team Family Outing

These filters are a great choice for anyone looking for a simple, reliable solution for clean drinking water. They hold up well, even after repeated use, and the price point is definitely better compared to other similar filter straws on the market. I’ve compared them side-by-side with more expensive brands, and these perform just as well, if not better in some cases.The 5-stage filtration system is a nice feature, removing 99.99999% of harmful substances while still maintaining the water’s mineral balance. The smaller 0.1-micron pore size ensures high filtration accuracy while keeping the flow rate fast enough for practical use. The compact size makes it easy to carry in your pocket, bag, or backpack, so it’s perfect for camping, hiking, or emergency preparedness.Overall, this is a great filter for the price, offering durability, efficiency, and convenience. Definitely recommend it if you’re looking for a portable and affordable water filter.

I’m sure I’m going to love having these soon! I’m an active outdoors person:) these straws will come in handy!

Straight into my go bag

These are nice personal filters. I just bought four more. The last one of the last batch had an issue, though, it wouldn't pass air. If the chamber between the entrance and exit got any air in it whatsoever then it became vapor locked and impossible to use. It meant taking it apart and priming it before every use, sometimes twice as it wasn't a very easy maneuver. I don't know what happened with that one. Every other filter has behaved normally and last quite a long while. I have no idea why the osmotic membranes refused air passage, but that one also back flushed very easily, too. QC may be an issue if one in four is bad. We'll see.[Edit: The new ones seems very slightly redesigned, not exactly the same size and have a few minor improvements. So far, working as intended.]

So after camping in pisgah national forest for 3 weeks these were invaluable. They are super lightweight and durable. They functioned perfectly and are a great design.We tested muddy puddle water strained through these against city purified water and these wonAlso very easy to clean.

Fast shipping, have not used them but will review when I do.

Just what I was looking for and an easy size to pack. Well made and delivered quickly

Everyone needs these haven’t used them but I think I should keep them handy for my family
