Review on Optimized HydroBlu Versa Flow Water Filtration System by Robert Mac

is MUCH better than the Sawyer Squeeze. We got so tired of backwashing our Sawyer over and over again (because it was very slow even with very clean water) that I was close to going back to our trusty pump filter (Sweetwater). Then we saw one of the hikers pull out one of these babies and filter it out very quickly. They're the same price and filtration rating as Sawyer, but they work much faster. No problems with taste or transparency. This is our obvious choice. Works with Platypus, Sawyer, Evernew or Smartwater bags or bottles. I don't roll bags ('bubble'). After filling them, I find a sloping rock to sit on and place the bag under my thigh with the end of the filter hanging down so the water bottle can be brought to the filter. Then a simple seated squeeze pushes the water through. It's much easier on hands and pockets.
