Our take on the Joypur Portable Water Filter Straw
The Joypur is a personal filter straw that you drink through directly or drop into a bottle. Its 0.01-micron hollow-fiber membrane is rated to remove 99.99999% of E. coli and other contaminants, and each filter is rated for up to 1,000 liters. At 5.6 inches long and 0.18 lbs, it packs smaller than most pump filters and needs no batteries or pumping. It suits hikers, campers and travelers treating water for one person at a time; rivals like the Sawyer Mini and LifeStraw match the pore size but differ in flow rate and how they mount to bottles.

Questions and answers
- How long does one filter last?
- The filter is rated for up to 1,000 liters (264 gallons), roughly a year of typical personal use. Lifespan drops if you filter cloudy or silty water.
- Does it remove viruses?
- No. The 0.01-micron membrane is rated for bacteria and protozoa such as E. coli, but not viruses or dissolved chemicals. For virus-risk water, combine it with purification tablets or boil the water.
- Can I use it in a bottle?
- Yes. At 0.7 inch in diameter it fits many bottle and cup openings, so you can drink through it from a filled bottle or straight from a source.
- How is it different from a pump filter?
- It is lighter and has no moving parts, but it filters more slowly and serves one person at a time. Pump filters suit groups and filling bottles faster.
- What is in the box?
- The set is listed as 4 pieces in black. Check the listing for exactly which accessories are included, since a backflush syringe is not stated.
- Do I need to clean it?
- Yes. Backflushing with clean water after trips keeps the flow up; without regular cleaning, silt and debris shorten the filter's life.
