Fits all Riccar Old 8000 Series using a split filter (two separate post filters). These are 3M Filtrete exhaust filters. #RF8-2
These filters are not an exact match for the Old Simplicity 7 Series. See Simplicity SF7-2 for correct filters.
The manufacturer recommends to change/replace these filters after using 12 vacuum bags or once a year to maintain efficient filtration. Do not attempt to clean and reuse as suction and filtration performance would be greatly reduced.
