Persistent cabin odor or reduced air freshness can have several causes, and the cabin filter is one sensible item to inspect. BYD's SEAL owner manual advises owners to inspect, clean or replace the filter regularly and to contact an authorized service provider if odor persists.
Start with the official maintenance guidance
Filter service should follow the maintenance information for your exact SEAL market and model year. Driving in dusty areas, salt-laden air or other severe conditions can justify closer attention. Do not treat a generic online interval as a substitute for your vehicle documentation.
Choosing the correct filter
GlobalBYD currently lists Cabin Air Filters for BYD Seal & Seal U/Sealion 6 with two part-number options. Because the listing itself presents multiple part numbers, verify the existing filter, VIN/market information or service documentation before ordering rather than guessing.
Odor-reduction habits
BYD's owner guidance recommends ventilating with natural air before parking to help keep the cabin relatively dry, keeping the cabin clean, and inspecting the filter regularly. If odor remains after basic prevention, professional diagnosis is appropriate.

Safety and compatibility
Never force a filter into a housing, damage HVAC components or assume SEAL and SEAL U parts are interchangeable. Follow the owner/service documentation for access and orientation.
