Hello wtcmedic, Thanks for writing a review! From your photo posted, it appears you're not using the correct filter bag for the vac. The cartridge filter goes over the filter cage where you installed your filter bag and the correct filter bag with part number VF3501 should be placed in the drum. If you have questions or you need assistance, you may call our Customer Service at 1-800-474-3443 from Monday through Friday between 8:00 AM to 5:00 PM Central Time and we'll be glad to assist you. Or, email us at info@ridgidvacs.com. Thanks, RIDGID
