How to replace the exhaust filter in an Electrolux Harmony canister vacuum cleaner

For an Electrolux Harmony canister vacuum, the owner's manual recommends replacing the exhaust filter every fifth time you change the vacuum bag.  Follow these steps to replace your Harmony's exhaust filter.

With the vacuum off, pull up on the two plastic tabs on the rear side of the vacuum.  Once you have pulled those tabs up, the whole rear cover can be removed, exposing the exhaust filter.

The exhaust filter in your Harmony should look like the one in the picture above (though the coloring of the plastic may vary).  Pull the exhaust filter out by grasping the plastic tab on the left side, then install the new filter in the same orientation, with the tab on the left side.

With the new filter installed, reattach the rear cover by sitting it back on the vacuum and snapping the tabs in place.  Once the rear cover is reattached, your task is complete.
