Also good for extended stays outdoors, camping, hiking boating and such. ### ⭐⭐⭐⭐⭐ Great value for the price, they work great (never got sick, use every day) *by A***2 on May 5, 2026* Use these on my hikes every day. To drink out of the streams along my route. Haven't got sick, so I take it they work. Great value. Have used about 150 times so far (on only one of them), and it's still going strong. So, they last as long as advertised as well. You'd be crazy not to keep one on u in the woods. Weighs basically nothing and can purify 10k+ gallons of water. No brainer. ## Frequently Bought Together - Membrane Solutions Straw Water Filter, Survival Filtration Portable Gear, Emergency Preparedness, Supply for Drinking Hiking Camping Travel Hunting Fishing Team Family Outing - Aquatabs 397mg Water Purification Tablets (100 Pack).
