So the solution is simple: put a scrim filter from APD. Just cut it to the right size and you won't have any sorb particles.
I use one on each cassette of my rEvo and it works very well.
Mould growth on scrim, need to remove whole OPV body from lung to clean/replace scrim (which will likely clog up relatively quickly with fine wet sorb dust) and the fact scrim is quite hydrophobic suggests to me at least its not a good filter choice for this application.
SS mesh, just fit it forget about it
