NFPA 96 states that all hood filters must be treated the same as the rest of the exhaust system. They should be well maintained.
Essentially, all removable parts of a kitchen exhaust system (grease cups, trays, hood filters, heat shield devices, etc.) are your customer’s responsibility. Non-removable parts are your responsibility as the hood cleaning contractor.
Your customers should understand that clean-looking filters are a by-product of proper filter maintenance and not the end goal. All parts of the exhaust system must be properly cleaned and maintained prior to becoming heavily contaminated with grease.
