Jealous of your weather and activities! Great photos, thanks.Both cans worked very well, and did their job. As normal with OCC, the fluid is a mix of oil and water condensate. There was probably 25 - 40 ml in the right can and 50 - 75ml in the left.
I know that @GMS asked about the screen or porous media, I say keep the filter we have. No need to swap, as it appears to be doing its job well.
