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

The Electrolux Harmony canister vacuum cleaner has two filters in it: a motor filter and an exhaust filter.  According to the user manual, Electrolux recommends replacing both filters every fifth time you change the vacuum bag.  This article describes how to replace the motor filter.

In order to remove the filter, you first need to remove the vacuum bag.  Grab the handle on the front of the vacuum, under the hose, and pull up.  The front cover will lift up, exposing the bag.  Remove the bag using the handle on its plastic housing.

With the bag removed, you can see the filter.  It will be a white squarish filter in a plastic grid housing.  (The housing will probably be green.)  Slide the plastic filter assembly straight up to remove it.

Remove the filter from the plastic housing, and set the new filter in its place.  Then slide the plastic filter housing back down into its slot.  Now reinstall the bag, making sure that it sits flush with the vacuum sides (otherwise the top won't close right).  Once the bag is in, close the cover, and your filter change is complete.
