OK, filter straws are ok for emergencies. Pump filters are better. PURIFIERS are best.

I'm thinking about getting a Sawyer (Squeezable) system for the bob/Get out of dodge QUICK or just if we go walking around somewhere. They filter down to 0.1 micron. I am ALSO considering their complete system (the one that filters down to 0.02 micron) as the main system. It has two "Bladders", one for dirty water that gravity feeds into the clean water bag after going through the filter. Sawyer guarantees them for 1 million gallons.

Do you think this would be a good system or should a regular pump system be considered?

Sawyer systems/specs can be found here.
