Our take on the Portable Water Filtration Straw - Blue

A personal water filter built into an 8.25-inch straw, 1.29 inches across, that lets you drink straight from lakes, streams or taps without a pump or bottle. Filters of this type typically remove bacteria and protozoa but not viruses or dissolved chemicals, so they suit backcountry and emergency use rather than treating polluted tap water. It is a low-cost, packable backup for hikers, campers and travel kits. No current store price was given for this listing, so compare it against the $15 to $25 that straw filters usually sell for before buying.

Questions and answers

Is a filter straw worth it?
Yes as a backup or for clear backcountry water. It is cheap and weighs almost nothing, but it will not make chemically polluted or virus-contaminated water safe.
What does it filter out?
Straw filters of this design typically stop bacteria and protozoa such as E. coli, Giardia and Cryptosporidium. They generally do not remove viruses, heavy metals or dissolved chemicals.
Can I use it on tap water?
It will improve taste and catch sediment, but it is not a purifier. For known contaminated municipal water, use a certified pitcher or gravity purifier instead.
How do I clean it?
Backflush it with clean water after each trip and let it dry before storage. Never let it freeze, since ice can crack the hollow fibers.
When is it cheapest?
Straw filters see the deepest discounts during spring outdoor sales and pre-hurricane-season promotions. Check the price history before buying at full price.
