These aren’t my mods, but a couple I’ve read about in a few places that I think are worthwhile.  On the Long Trail, I treated my water with AquaMira and a bandana as a pre filter when there were a ton of floaters.  Based on what I’ve read about water sources in the Desert section of the PCT I’m going to want a pre-filter of some sort.  With some testing at home, the screen in adapter seems to work well.  I’ll update this on the trail if it fails or if I MacGyver anything else.  In the meantime here are some tips in no particular order:

1. Buy a Sawyer SP150 Coupling:
2. The syringe the Squeeze comes with is good at back flushing, but not necessary when I can just use the adapter and a clean water bag.   One less thing to worry about.  There’s a thread about it on WhiteBlaze.net
3. Use the plastic cap to keep it clean.
4. If temps are going to drop below freezing at night, put the filter in your bag/quilt with you to prevent it from freezing.  If you can blow air through it after you suspect it’s been frozen, it’s definitely broken.
