This summer I am going on a camping trip with a group totaling five people including myself. We're not going backpacking per se but, more like setting up a base camp by a remote lake and probably doing short day hikes from there. Three of the campers are new to camping.

Obviously, water availability will not be a problem but filtering enough for 5 people's cooking, drinking, and washing needs might be. On my own solo backpacking trips, I use the full sized Sawyer Sqeeze with an Evernew bag in a gravity feed setup which, provides plenty of water for me or me and a partner.

I've looked at the 2019 CNOC Vecto 3L bags and just might get two of those, one as a clean bag and one as a "dirty" bag configured in a gravity setup. At least that would give me 3L at a time.

Is there a better system out there (that won't cost a fortune) that would filter large amounts of water at a time? Thanks
