I inherited an old Filter Queen vacuum from my mothers estate , heres a reference picture i found online-
I had no idea how it worked or where to buy replacement filters, while looking around the internet i came across a forum much like this one but for vacuum collectors , its a nice group of people with a mix of both men and women. I joined the group but dont consider it as a 'hobby' for me but alot of those people take their vacuum collections very seriously (LOL)
