Personal Water Filter - Survival Filter Straw with Bottle Thread

A filter you left at home does nothing for you. This personal water filter is 5.3 in (13.5 cm) long and small enough to live in a pocket or a go bag, so it is already with you when the bottled water runs out on a hike or during a storm.

Sip straight through it, or use the thread on the end and screw it onto a 28 mm bottle. An O-ring seals the connection, so a bottle of stream water becomes something you can drink from on the move. The maker rates the filter at 0.01 micron and up to 1056 gal (4000 L). There is nothing to charge and nothing to pump. Use it on fresh water only. It is not made for salt water or water carrying fuel or chemicals, and a filter does not remove what is dissolved in the water. Where you are unsure of a source, also boil or treat it.

That bottle thread is what sets it apart from a plain sip straw, because you can carry filled water with you and drink from it later, or fit it to a squeeze bag. For hikers, campers and anyone building an emergency kit, it is one small filter that works with the bottle you already carry.
