Baffle filters are the first line of defence in your commercial kitchen extract system. They capture the initial grease before it enters the ductwork, protecting the wider system from rapid grease accumulation. This makes regular filter cleaning and timely replacement a critical maintenance task.
In a busy commercial kitchen, filters may need cleaning weekly or fortnightly. But even with regular in-house filter washing, periodic professional deep cleaning of the canopy body and filter housing is essential.
Baffle filter cleaning
Professional filter cleaning goes beyond a quick wash. Filters are degreased using specialist solutions that break down baked-on grease deposits that standard kitchen cleaning cannot address. After professional cleaning, filters perform closer to their original specification.
Filter replacement
Where filters are damaged, warped or beyond effective cleaning, replacement is required. Continuing to use damaged filters allows grease to bypass the filter and enter the ductwork at an accelerated rate.
Establishing a filter maintenance schedule
Specialist providers can assess your filter condition and recommend an appropriate maintenance schedule based on your kitchen output. For high-volume operations with heavy frying, a structured filter management programme — including professional cleaning intervals and planned replacement cycles — helps maintain system performance and protects compliance records.
Types of filters
Baffle filters are the most common type in commercial kitchen extract systems. They are designed to be removable and serviceable. Cassette and mesh filter types are also found in older systems. Specialist providers can assess and advise on any filter type.
