Shepherd Filters are disposable kitchen grease filters made from 100% wool. Wool is naturally flame resistant and bio-degradable and therefore, safe to dispose of in your regular waste bin! Wool is the obvious choice for anyone concerned about the environment (and much safer to use than cleaning chemicals).
Yes, filters are designed to retrofit to existing kitchen hoods.
In terms of food safety, as the Shepherd Filter has no real direct contact at all with the food produced, there would be no risk.
Based on the relative position of the filter in the hood and the Shepherd Filters construction, the use of the UL listed grease filters in an existing hood will not alter the hoods function, operation, or infringe on the certification of the existing hood.
Our product has been tested, listed and certified to all or more of the same standards that your current metal filters have been subjected to. With that said, the liability should not change at any level.
- AS 1668.2 E6 Kitchen Exhaust Hoods Incorporating Grease Removal Devices
- NFPA 96 Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations
- UL1046 Flame Test

Our Filter Change Guide will ensure that you know when it’s time to replace a filter. The best time is generally in the morning before equipment switched on.
If your laminated guide is missing from the wall, please contact us immediately and we will send you a new one.

The frequency and colour of the filter will be affected by the equipment being used and what is being cooked. See below for an indication based on the cooking equipment that may feature in your kitchen:
*Times may vary due to hours used per day and types of cooking.
Here is a quick demonstration on how a Shepherd Filters kitchen grease filter is replaced:
Shepherd Filters capture up to 98% of airborne grease before it enters the exhaust duct without restricting airflow, when the wool filter media and frame are used together.
Easy to use, our products come with the peace of mind that they have been:
• Airflow tested
• UL1046 flame barrier tested; and
• HACCP approved
Shepherd Filters is the result of many years of development, receiving the UL 1046 standard in 2006, as well as AS1668 and NFPA 96. Shepherd Filters is patented in the USA, Australia and New Zealand. It is protected in numerous countries due to the specific natural formula of the product in regards to weight and loft. This formula optimises the capture and containment of grease particles without a restriction of airflow to the exhaust hood system.
Wool is an excellent fibre when it comes to fire safety as it is naturally flame-resistant.
Wool may be ignited if subjected to a significantly powerful heat source, but does not normally support flame and will instead smoulder (usually only for a short time).
