I went and bought one of those cheap gas syphoning tools that you just hand pump. They are like a dollar at the dollar store or a couple of bucks at AutoZone. They weigh almost nothing, haven’t actually weighed it, but that fills the bag up quite quickly.

I also made a cap for the fill side of the filter using an old 2 liter cap and the end of the 2 liter. That’s so no contaminated water leaks out when im just carrying it around. As i keep it in a zip lock baggie also.

Ill have to try the baggies as the scoop method.
