Can you point us to more detail about this mod? TIA
You basically take some needle or 1mm flat screwdriver (or anything similar) and remove that stock white filter from Rosefinch.
Then you pick 4.5mm 350/400/450 filters like this (try the density that sounds better to you) https://www.aliexpress.com/item/1005006137203461.html
(I think 5mm might be actually better and easier to install, but I couldn't find 5mm "cotton" meshes on Ali unfortunately, only metal ones)
You can also re-glue old stock filters to holder of new filters, in case you don't like the mod.
And with the same needle or screwdriver you then install the new mesh on the nozzle. They have traces of glue to they will hold, but 4.5mm filters are slightly tricky to position properly.
ps: that is how I did it. Hopefully it's the correct way and correct meshes, but if not - feel free to correct me.
I might actually had 450 on Rosefinch after all, it's all relative. Get 5.0mm one if you can, that's probably the size of original filter. 4.5mm filter works, but barely covers the nozzle, so gotta place it on the right spot.
