I have a question regarding my Electro Hygiene canister model 596. For starters, I need to do something with the felt exhaust filter inside along the bottom. When running, it sounds like it is trying to force the exhaust air out with great effort. Can I assume that this is because the filter is dirty and needs replacing? And, if so, can it just be cleaned and reused? I will bet any money these felt filters are no longer available much like the Filter Queen "batting" as it is referred to.
Also, the grey exhaust plug is dry rotted. I cannot find any of these as these parts are long gone! I have discovered that the round belt cover plug that is found on the older Royal Handvacs, (the red ones), can be used. It's not the best fitting, but it works. By chance, does anyone know where to get the old gray plug with the pointed tip?
