Range Hoods

The aluminum mesh grease filters should be washed in your dishwasher approximately every month depending on the amount of usage. Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergents, or as a result of local water conditions — but this will not affect filter performance. This discoloration is not covered by the warranty. To minimize or prevent discoloration, wash filters separately in the sink with a mild detergent. Wash often if your cooking style generates greater grease like frying foods or wok cooking. You cannot clean/wash the non-ducted carbon filters; they must be replaced.

Baffle filters, which are used in professional style range hood products, are designed to operate longer in high grease conditions without loss of performance. Generally, these need to be cleaned with soap and water whenever the surfaces become unsightly.
