How to Choose Commercial Kitchen Extraction Filters
The most overlooked component of the commercial kitchen extraction system are the filters. This article describes why it’s worth investing time in selecting the correct ones in the first place.
Know Your Filter Type
Baffle filters are ideal for extremely dirty kitchens as they use a mechanical separation of grease and air. This makes them easy to clean. Baffle filters are normally used in very busy kitchens with lots of grease. Mesh filters are cheaper but will clog up much quicker than baffle filters and are better suited to very clean applications such as a café that only cooks lightly. Cassette filters are mid-range kitchen filters and are widely used in commercial canopies.
Check Grease Capture Efficiency
When choosing kitchen extraction filters look for a grease separation efficiency rating. For busy commercial kitchens look for a filter that has a rating of over 85%. This will stop grease from entering the ductwork and causing a fire risk and extra cleaning costs.
Match the Filter to Your Canopy
Check that the filter has been specifically designed to fit your canopy’s face openings. It’s also important to check the airflow rating of the filter to ensure it matches the volume of your canopy’s extraction system.

Choose Stainless Steel for Durability
A pressed stainless steel filter will withstand regular washing, extreme temperatures and even harsh degreasing products without warping. Even though aluminium filters are lighter in weight and easier to ship, they can begin to degrade much faster if subject to heavy use. Also, a filter that maintains its shape will provide proper sealing.
Check Fire Suppression Compatibility
Does the kitchen use a fire suppression system? Some mozzons are specific to certain filter types, so make sure the kitchen’s filters are compatible with the system installed within the canopy. Ventilation performance standards for commercial kitchens also need to be met.
Prioritise Easy Removal
Simple removal of filters, often by a quarter turn of a wrist or release of a single clip, means they will get cleaned more often. Awkward fitting means they will get ignored by staff.
The filters are the most critical component of your commercial kitchen extraction system, enabling the remainder of the system to function effectively.
