Membrane Solutions Portable Water Filter with A Official Carry Case, Emergency Water Filtration Straw Survival, Lightweight 5-Stage Water Purifier for Camping Hiking Backpacking and Tactical Gear

It is questionable because it is a Chinese product, but it is said to be effective in situations where there is no drinking water. I think it is a good idea to buy at least one.

Parfait pour les promenades ou camping ne prenez pas de risque filtre l'eau è merveille.

Arrived on time, was packaged well. Like the included carry case, protecting the filter while stored It's in my get home bag Good quality e filter, lightweight, compact

I received an automated refund because apparently the item that was shipped was damaged. I'll stick with Lifestraw, they have proven reliable again & again.

Works like a charm and can be a life saver.
