Quickly filters
Wuick easy way to filter. Ive noticed a difference in taste with these as well. Less heavy metals. Easy to use and lasts a while. Worth trying for the cost.

Inconvenient and possibly useless in an emergency
It has to be soaked in clean water before use, and you can't drink for the first few sips. You also must backwash after use with clean water. May I ask, when using in an emergency, if drinking from a poor water source, where do you find clean water to flush? This means you have to soak and use before taking on hike or in an emergency. Ours are in our bug out bags still in the box.

Better than the Life Straw
Solid choice for a filter. First, this is a certified filter, something many of the cheaper filters are not. Second, the second stage of carbon filtration greatly improves taste. Finally, it is threaded for 28mm bottles (such as the smart water bottle). The Sawyer life straw has fewer features and cost much more!

Da avere sempre con se
Articolo come descritto. Forse un po' complicato aspirare acqua ma inserito in una bottiglia di plastica si può filtrare più facilmente.
