This SEBO micro/odor filter is for use in the Automatic X and Essential G series upright vacuums to keep them performing well. This long tubular filter also contains activated charcoal which is great for trapping pet odor, as well as other household odors. It can be used instead of the white tubular X/G series microfilter that is located beside the paper bag in the vacuum. It includes the mounting frame so changing it is a breeze... just slide the dirty one out and slip this one into place.
