Kitchen hood filters: wash metal grease filters, replace charcoal types
Bosch and Samsung distinguish washable removable metal grease filters from charcoal odor filters that usually require replacement. Turn the hood off and let it cool before servicing according to the manual.
Cleaning depends on whether the hood vents outdoors or recirculates and on its filter type. Bosch allows gentle soap-and-water cleaning and sometimes a dishwasher for metal grease filters. Charcoal filters follow their separate replacement schedule.
