Micromesh and aluminum filters may be cleaned in a dishwasher at least once a month, depending on use.
NOTE: Grease filters are dishwasher safe. Clean all-metal filters in the dishwasher using a non-phosphate detergent. Discoloration of the filter may occur if using phosphate detergent or as a result of local water conditions — but this will not affect filter performance. This discoloration is not covered by the warranty.
