Rated2out of5bydeffenspfromNice idea but poor implementation.The filter is easy to use and fits in my water bottle just fine, but the filter pouch pops open if the bottle is agitated or if it isn't set down with the gentlest of touch. I have only used it for a day, with my bottle clipped to my hip, and the carbon pouch has fallen out several times--and as of the last fall, burst open and filled my bottle with charcoal. It might work ok for sipping while sitting at a desk but it certainly isn't trail ready.
