Shepherd Filters Disposable Grease Filters 550x450mm (Pack of 50)

Shepherd Filters are disposable wool filter sheets designed to sit within a commercial kitchen canopy and capture airborne grease before it travels further into the extraction system. They work alongside standard metal baffle filters rather than replacing them, providing an additional layer of protection at the point where grease becomes airborne during cooking.

In a busy commercial kitchen, standard baffle filters handle the bulk of grease capture but are not designed to stop finer airborne particles. Over time, grease that passes through accumulates in the ductwork, fan housing, and further along the extraction system — areas that are costly and time-consuming to clean professionally. Shepherd Filters sit in front of this problem, reducing how much grease migrates beyond the canopy in the first place.

For kitchen operators, the practical advantages are straightforward:

• Reduces grease build-up in ductwork, lowering the frequency of professional duct cleans
• Keeps canopy interiors cleaner between scheduled maintenance visits
• Disposable design removes the need to clean heavily soiled filter media
• Simple to fit and replace, requiring no tools or specialist knowledge
• May support compliance with TR19 ductwork cleanliness guidance by reducing accumulation rates

Installation is straightforward — the filter sheet fits inside a compatible frame within the canopy. It is worth confirming that your existing canopy accepts the 550 x 450mm sheet size before ordering, as canopy configurations vary. Replacement frequency will depend on cooking volume and menu type; high-grease operations such as fryer-heavy kitchens will typically need more frequent changes than lower-output sites.

These filters are well suited to takeaways, pub kitchens, casual dining restaurants, and contract catering operations where ductwork maintenance costs and compliance are ongoing concerns. For very high-volume or heavy-duty extraction systems, it is worth discussing whether a different filter configuration would be more appropriate for your setup.

If you are unsure whether these filters are compatible with your canopy or would like guidance on replacement frequency for your kitchen type, the team is happy to help you work that out before you commit to an order.

Please note that the baffles and frame are not included, this is a refill pack for the filters only.
