Is This the Right Part?
Confirm the complete model number before ordering. Similar filters may differ in frame dimensions, media grade, or mounting tabs.
Common Symptoms
- Dusty or dirty air blowing from the exhaust port
- Reduced suction power despite a clean bag or cup
- Musty or stale odour during vacuuming
- Visible dirt or debris on the exhaust filter frame
Check Before Replacing
- Confirm the vacuum bag or dirt cup is empty and properly seated
- Inspect the pre-motor filter — a clogged pre-motor filter can mimic exhaust issues
- Check all hose connections and seals for cracks or gaps
- Verify the filter housing cover is fully latched and sealing correctly
