Keep your Dirt Devil central vacuum system running cleanly with this OEM-style replacement bottom filter support. Designed to sit at the base of the vacuum bag canister area, this support holds the filter bag in proper position so your central vac captures debris effectively rather than letting it bypass into the motor or canister walls. At 6 x 6 inches, it drops into place as a direct swap for the original worn or broken piece.
The bottom filter support is a small but critical component in the Dirt Devil central vacuum canister assembly. When this support cracks, warps, or goes missing, the filter bag loses its stable base and can shift during operation -- allowing fine dust and debris to escape around the bag rather than being captured inside it. The result is reduced suction performance and potential contamination of the canister housing.
Replacing this part with the correct HP Products 4928 restores the bag to its intended seated position, ensuring the full filter surface is engaged on every pass. This is a common maintenance item for RVs and manufactured homes equipped with Dirt Devil built-in central vacuum systems, especially in rigs that have logged heavy seasonal use.
Sized at 6 x 6 inches to match the original canister opening and drop in without modification.
Supports the filter bag base to prevent shifting during operation and maintain consistent suction.
No tools required for installation. Slides into the bottom of the canister bag compartment as a direct replacement.
Package includes one (1) bottom filter support -- exactly what is needed for a standard canister replacement.
A damaged or absent bottom filter support is one of the most overlooked causes of poor central vacuum performance. Before replacing motors, hoses, or bags, check that this support is intact and seated correctly. A $10 fix often solves what looks like a major suction problem.
Built-in Dirt Devil central vacuum systems are common in Class A motorhomes, fifth wheels, and manufactured homes. Vibration from road travel can accelerate wear on plastic canister components like this support. Inspecting and replacing this part during routine bag changes is good preventive maintenance for full-timers and frequent travelers.
