• Best For: Owners of an Electrolux Discovery upright or a Perfect Products C101, C103 or C104 who want a single bag pack that covers both machines.
• Highlight: EnviroCare cross-references this Style U bag to the Perfect Products C101, C103 and C104 as well as the Electrolux Discovery, so a mixed fleet can stock one part number.
• Expert Note: Change the bag at about two-thirds full rather than waiting for it to pack solid. Micro-filtration media loses airflow well before the bag looks full, and suction drops with it.
