I am sensitive and especially sensitive to the taste of water. I really can tell the difference drinking the water from Flaska. The water in the Flaska bottles is excellent. Sometimes I’ll get a stomachache drinking even filtered water, but I noticed that never happens with the water from the Flaska bottle. Awesome!
