I haven’t had to utilize these yet, but one of the things that drew me to them is I can screw a waterbottle to the straw and take it with me. I am not required to stay at the source to filter or drink water directly from the source. They are super lightweight and are made of durable polymer so they won’t crumble or break in a backpack.

Straight into my go bag

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

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.]

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

So far so good. Makes water taste distilled.

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

Perfect
