You are doing it wrong. You put the bottle on the ground and the bag 8' up in a tree this gives you 2.3x8=18.4psi. When the bag is drained you still have 2.3x7=16.1psi. I don't care how strong you are but you are not filtering faster in a squeeze device. Even if you are putting 200lbs of force through the 30 sq inches that are your hands you will only have 6.7psi at the filter. I can filter 5L in under 2 minutes filter speed is mostly about backwashing the filter regularly. No serious group of hikers brings a bunch of snqueeze devices. They bring one or two gravity devices.
