why do cooking smells linger with my recirculating rangehood?
a recirculating rangehood returns filtered air to the kitchen, so declining carbon-filter performance can leave cooking smells behind. greasy filters, restricted airflow or a fan fault can produce a similar complaint.
confirm that the hood is set up for recirculation and uses carbon cartridges. follow the manual's care instructions for its user-accessible grease filters first. if the fan is not running normally or airflow remains weak, more carbon filters are not a substitute for finding the restriction or fault.
the linked carbon-filter guide is relevant when the disposable cartridges are due for replacement or no longer control odours. these cartridges are replaced, not washed. the offers include different diameters and mounting formats; hood width alone does not establish a match. check the full model and the existing cartridge's size and locking arrangement.
first checks
- separate odour from airflow
note whether airflow has weakened as well as odour control. switch off and disconnect as instructed before removing user-accessible filters.
- identify the cartridge
check the manual and old filter format. do not treat a metal grease filter and a disposable carbon cartridge as the same part.
