Katadyn BeFree vs Platypus QuickDraw

“Yesterday bought a new Platypus Quickdraw, and it failed the integrity check out of the box, even after filtering several liters of water. I was going to take it back today, after hearing all the stories of them failing out of the box. But I wondered if maybe it was the kind of thing where when it's brand new, air just gets trapped in some of the micro tubes, and because a new one filters so fast there's not enough pressure to force the water into every part of it I wondered if letting it sort of soak over night would help. So I filtered a bit, capped both ends, and let it sit till morning, and now it passes the integrity check! Worth a try if you have one that fails out of the box.”

“I live in an area with tough water sources and everyone I’ve ever known that used a BeFree clogged their filter and had it die a very early death. I would never buy any filter you could not back flush. I think they’re shitty but just my opinion based on the four or so I’ve seen fail.”
