Yasbean, I put in an order for a couple of these filters but it will take some time for this order to get to me. By the way, I completely took my Hottop apart after doing about 100 roasts in it. There was chaff all over the electronics compartment and yes, Yasbean, a lot of those "fuzzy coffee oil hairs" growiing out of almost everything there. Except I am not sure if those are oil hairs or fungus? Can oil make those moldy-looking fuzzy hairs? It was yuck time, but it took all of just 30 minutes for me to clean up all that gunk, and restore the innards of the Hottop to pristine condition. Now, I'm ready to do those Geshas!
CoffeeCarl, the Scotchbrite suggestion is fantastic. I will try that out asap! Many thanks!
