Metal kitchen grease filters only stop between 20-40% of airborne grease, allowing the rest to pass through into the hood/canopy, duct and fan. This results in ongoing costly cleans as well as the potential for premature equipment failure.


The Shepherd Filters disposable wool filter media provides the best solution. Capturing up to an impressive 98% of airborne grease before it enters your kitchen exhaust system, Shepherd Filters virtually eliminate the need to clean filter frames in-house or through a filter exchange company. This equates to a cleaner system year-round, saving you time and money as well as reducing your risk of fire.

Kitchen Grease Filters Explained: Restaurant Exhaust Safety

Kitchen grease filters are one of the first lines of defence for restaurant safety. Kitchen grease is highly flammable, therefore replacing and maintaining a restaurant’s grease filters is an important step in reducing the risk of kitchen grease fires.

Most people think of grease as a liquid, but grease can also travel by vapours and smoke. If the exhaust effluent is properly filtered, a large percentage of this grease is removed from the air stream. This not only greatly reduces the amount of grease that will stick to the inside of the kitchen exhaust hood, it also reduces the risk of a grease duct fire and the need for kitchen exhaust cleaning.

Shepherd Filters come as pre-cut sheets in all standard sizes.

They are used in conjunction with a specially designed UL1046 stainless steel frame, making the filters easy to use and highly effective.


The National Fire Protection Association (NFPA) Code 96 is the standard for ventilation control and fire protection of commercial cooking operations.

Below we have listed some of their fire safety codes described in NFPA Code 96, specifically for kitchen grease filters:

                        • Listed kitchen grease filters, listed baffles, or other listed grease removal devices for use with commercial cooking equipment shall be provided.
                        • Listed kitchen grease filters and grease removal devices that are removable but not an integral component of a specifically listed exhaust hood shall be listed in accordance with UL 1046.
                        • Mesh filters shall not be used unless evaluated as an integral part of a listed exhaust hood or listed in conjunction with primary kitchen grease filters in accordance with UL 1046.
                        • Filters shall be listed and constructed of steel or listed equivalent material.
                        • Filters shall be of rigid construction that will not distort or crush under normal operation, handling, and cleaning conditions.
                        • Filters shall be arranged so that all exhaust air passes through the grease filters.
                        • Filters shall be easily accessible and removable for cleaning.
                        • Filters shall be installed at an angle not less than 45 degrees from the horizontal.


This dramatic reduction of grease entering the kitchen exhaust hood system brings immediate savings in reduced labour costs of ongoing baffle filter washing, reduces the number of necessary kitchen hood cleanings, roof damage costs, and provides energy savings from cleaner rooftop equipment.


The overall result of the Shepherd Filters disposable oil and grease filters is less hassle and money savings for a commercial cooking operation. With the reduction of filter cleans, kitchen hood cleaning and the energy savings this attracts Shepherd Filters are being installed all over Australia and across the Globe, including New Zealand, Asia-Pacific, UK, Europe and the Middle East.
