Hey there, Im the guy who wrote that air filter cleaning post. Mine did not have that, but I don’t think you should have vacuumed up the rocks haha why would you think your machine was putting rocks into your filter? THose rocks look like a new addition to the filter I presume as mine did not have those. Under that, from my post you can see I did cut out the glued part (I had to to get to the rest), so that I could shake out and vacuum the rest of the filter.
How old is your filter? I can’t tell if that is the old model or the new one. Under your rocks I see the filter that was in my photos which I took out and that is what needed to be cleaned. check my post
