Cordless SEBO vacuum leaves fine dust haze or odor in the air; allergy symptoms worsen during use.

Safety first: Remove the battery before opening the filter compartments.

• Inspect exhaust filter: Remove the HEPA or microfilter. If it is gray, torn, or deformed, replace it with a genuine SEBO filter.
• Check seals: Ensure the filter frame has intact rubber seals and that it seats firmly in its housing without gaps.
• Inspect housing: Look for cracks in the exhaust cover or body around the filter. Replace the cover or housing section if damaged.
• Use correct parts: Only use SEBO-specified filters; generic filters may not seal properly and can leak fine dust.
