Kitchen hood cleaning frequency really depends on how much you cook. If you're frying or grilling a few times a week, the filter will get greasy fast, so cleaning it every month is a solid habit. For lighter use, every three months might be enough, but if you let that sticky grime build up too long, your hood won't pull air as well and could even be a fire risk.
