Sawyer 3-Way Inline Water Filter

[DaFireMedic]

I use the Sawyer 3 way inline both as an inline on my pack and as a gravity system. I used to use it solely as a gravity system by filling a "dirty" bag with water, turning it upside down and letting the water flow through the filter into a clean bag. Since then, I just put water into my pack reservoir and drink it with the filter on the tube. I've thought about mounting near the cap on a 1 liter bottle and just drinking from the filter end, as I rarely carry more than 1 liter when water sources are known and plentiful.

Backflushing is easy in the field and it doesn't need to be a purified source. Just turn the filter around and let water flow through it.

I have a Katadyn mini-filter also. It works fine but is heavier and you have to pump from the source. I prefer not to use chemical treatment as it always adds that taste to the water and I try to drink as little chlorine or iodine as possible. I do carry 10 or so individually wrapped for a backup.

Am I missing something? You put "bad" water into the "good" side of your filter (to backflush) and say that's okay? What is there about these particular filters that I don't understand?

You are not missing something, I screwed up when I wrote that (long day at work). I was addressing someones question about backflushing in the field. I meant that you can use the water that you have, turn the filter around in your line and flush. It doesn't take much. My fault, I apologize.
