This package contains two white Exhaust Filters. One fits in a holder which pivots out from beside the bag chamber on Hoover Windtunnel and Royal UR30085 uprights. The filter measures 6 5/8" x 2 1/4" x 5/16" with the one end slightly curved. Each filter was previously green and know by #38766008.

The bag chamber lid must be removed to gain access to the filter and holder. If your Hoover Upright has a door on its side which opens to access thick filter, then you need the Upright Exhaust Filter or Bagless WindTunnel Exhaust Filter.   For similar products see our list of Royal Vacuum Supplies.
