Sawyer mini filter; sawyerstandard methodsSawyer basically claims compliance to EPA standards via 'standard methods' group. standard methods groupWhen you trace back what lifestraw utilizes, it gets to this; life strawNSF protocol is in compliance with the EPA Guide Standard and Protocol for Testing Microbiological Water PurifiersBetween them, the lifestraw is held to a more stringent standard from everything I can find. It concerns me that the group putting forth the sawyer variant felt it necessary to utilize alternative standards.

So basically it boils down to we could be playing Russian Roulette with some of these straw filters including the Sawyer models.

Their testing standard is not as stringent, but I would not go so far as to say it's Russian Roulette. If you wish to be ready for as much as you can, between the two, the lifestraw is tested to a more stringent standard. However, for normal conditions such as you may find on a hike etc. the sawyer should be safe.

Thanks for clearing that up more precisely for me. It's amazing how we purchase lots of gear without any aforethought of just how safe some of these items really are.

I have the Sawyer in-line filter attached to my Camelpak, also have the 2 liter water filtration system, and the sawyer personal water bottle filter.
