Product details
Foam sealing gasket for the HEPA filter in Prima and Wonder canister vacuums, part number B338-4700. The seal rings the filter and closes the gap between the filter frame and the canister body, so all of the exhaust air is forced through the media instead of slipping around the edge.
This is the component that makes filtration actually work. Foam that has gone hard, torn, or taken a permanent set lets unfiltered air bypass the HEPA element, and no filter can compensate for a leaking seal.
- Fits Prima and Wonder canister vacuums from Simplicity and Riccar
- Foam gasket for the HEPA filter position
- Replace whenever the foam is compressed, split or crumbling
- Genuine part, sold individually
A sensible time to fit a new seal is at a HEPA filter change, so the fresh filter is sealed properly from the first run.
