You can order it from Demci directly.
Just got a reply from them, the filters are 100 microns ~ (140 mesh).
Whether they can make or not a hard solid frame, no reply :/ I suppose still not. Prices are way over the top anyway
I will just buy a mesh elsewhere and DIY. Already found meshes from (250-30 microns) ~ 60-500 mesh.
The stock filter on front of R4 seems like (420microns) ~ 38 mesh.
Bottom (700 microns) ~ 28 mesh.
Anyone know of some good sources for a mesh with thin wires? Any idea what Demci uses exactly? It's pretty impossible to find and most seem to be sold to companies in bulk through god knows what distribution channels. Luckily Chinese resellers aren't as greedy nor secretive with items and will sell anything to anyone anywhere.
It's the bottom filter that mostly bothers me. Demci must be nice but with 100 microns, you gotta clean it all the freakin' time.Edited by JackCY - 7/24/15 at 6:21am
