Each straw runs water through a four-stage element rated at 0.01 micron. There is nothing to pump, charge or assemble: you put the intake end in the water and drink through the mouthpiece. The body is ABS.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1027\/6090\/7101\/files\/d9eeafa0-78e8-4bdc-b11e-d6971a0e6d6c.jpg?v=1793736992\" alt=\"Portable water filter straw with four-stage 0.01 micron element\"\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eFour straws per set, or eight if you take the double\u003c\/li\u003e\n\u003cli\u003eFour-stage filter element rated at 0.01 micron\u003c\/li\u003e\n\u003cli\u003eABS body, listed by the supplier as bottle type\u003c\/li\u003e\n\u003cli\u003eNo pump, no batteries, no charging and no setup\u003c\/li\u003e\n\u003cli\u003eDrinks directly from a stream, lake or stored water\u003c\/li\u003e\n\u003cli\u003eLight enough that one lives in each pack permanently\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/1027\/6090\/7101\/files\/5cbb8cf5-1efd-4849-b5e5-01589d7ee6f6.jpg?v=1793736991\" alt=\"Four pack of survival water filter straws laid out together\"\u003e\u003c\/p\u003e\n\u003ch3\u003eWhat 0.01 micron means in practice\u003c\/h3\u003e\n\u003cp\u003eMicron rating is the size of the gap the water has to squeeze through. At 0.01 micron the element is in hollow-fiber territory, fine enough to physically strain out sediment, cloudiness and the bacteria and protozoa that make stream water risky, because those are all physically larger than the pore. Viruses are smaller than bacteria, and the supplier does not publish a virus claim for this filter, so we are not going to make one. If you are filtering water you think may carry viruses, boil it or use chemical treatment as well.\u003c\/p\u003e\n\u003ch3\u003eWhy four straws rather than one\u003c\/h3\u003e\n\u003cp\u003eA single filter is the usual way these are sold, and it is also the usual way a group gets stuck. One person drinks, everyone else waits, and if that one filter clogs the group has nothing. Four means one per person in a family, or one in each of the car, the day pack, the bug-out bag and the kitchen drawer. The eight pack is the same idea for a bigger household or for splitting with family.\u003c\/p\u003e\n\u003ch3\u003eHow you actually use one\u003c\/h3\u003e\n\u003cp\u003ePut the intake end into the water and suck through the mouthpiece, the same motion as a thick milkshake through a straw. The first few pulls are harder while the element wets through. It will draw from a stream, a lake, a puddle, a water butt or a bottle you filled earlier. Back-flush it by blowing back through the mouthpiece when the flow slows, and let it dry before it goes back in the pack.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFiltration: Four-stage element\u003c\/li\u003e\n\u003cli\u003ePore rating: 0.01 micron\u003c\/li\u003e\n\u003cli\u003eMaterial: ABS\u003c\/li\u003e\n\u003cli\u003eContainer type: Bottle, per the supplier\u003c\/li\u003e\n\u003cli\u003eQuantity: 4 straws per set\u003c\/li\u003e\n\u003cli\u003ePack options: 4 straws (1 set) or 8 straws (2 sets)\u003c\/li\u003e\n\u003cli\u003ePower: None, drawn by mouth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKeeping it working, and where it lives\u003c\/h3\u003e\n\u003cp\u003eBlow back through the mouthpiece after use to clear the element, then let it dry fully before storing, because a filter put away wet is a filter that grows things. Keep it from freezing with water inside it, since ice can split a fine element and you will not be able to see that it has happened. Avoid drawing through heavy silt or salt water. Water you have filtered is for drinking soon rather than storing for weeks.\u003c\/p\u003e\n\u003ch3\u003eQuestions Shoppers Ask\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eHow many straws do I actually get?\u003c\/strong\u003e\u003cbr\u003eFour in a set.

Replace a straw when the flow stays slow after back-flushing.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDoes it remove viruses?\u003c\/strong\u003e\u003cbr\u003eNo virus claim is published for it, so treat the answer as no. At 0.01 micron it strains out sediment, bacteria and protozoa, which are physically bigger. For suspected virus risk, boil or treat chemically as well.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eCan I drink straight out of a stream with it?\u003c\/strong\u003e\u003cbr\u003eThat is what it is built for.

No straw filter desalinates.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWhat is it made of?\u003c\/strong\u003e\u003cbr\u003eABS.
