Can’t even use the filter because it doesn’t work with the bladder it’s suppose to go with.

I wish there was a standardized formate for comparing filters, some manufacturers talk about microns other talk about what they filter removes, other talk about certifications. After reading the epa description for what these filters should be removing I felt comfortable enough to use this in the US on a hike in a populated area. After using it for 4 day, the water tasted good , the filter never clogged or slowed down, and I didn’t get sick, thats a win in my book.
