This package #40110004 contains two Upright Exhaust Filters #38766009. Each filter fits inside a door on the side of the Standard Bagless uprights and many Non-Self-Propelled WindTunnel uprights. Each filter measures 6 5/8" x 3 5/16" x 1/2".

For the longer 10 7/16" filter, see the Long WindTunnel Exhaust Filter. If you need to remove the bag chamber lid to gain access to the exhaust filter and it fits in a holder which pivots out from beside the bag chamber, then you need the Small WindTunnel Exhaust Filter.
