Great to hear the background story.

I saw a YouTube video of a test of a different-shaped filter but it looked like the same "monolithic" type and at the end they said they had later pressurized the top bucket (or whatever they used) and got a much faster flow. It didn't take me more than a few seconds to figure out that a high head of water would work just as well as air pressure to speed things up. You could have the filter at the bottom of a vertical pipe but easier to handle would be a hose running from the input bucket to a much lower sealed container with the filter in the bottom.
