Baffle vs mesh hood filters for a commercial kitchen — which should I actually use?
My café's extraction hood came with mesh filters (the metal-wool-looking panels), and I keep being told baffle filters are what a commercial kitchen should use. Before I buy replacements I want to understand whether it's worth switching:
- What's the real difference between baffle and mesh for grease capture and fire safety?
- Which is easier to clean and lasts longer?
- Is switching to baffle genuinely worth it, or is mesh fine if I clean it often?
We fry and grill a fair bit, so grease is a real factor. What do commercial kitchens actually run, and why?

Short answer: for a commercial kitchen that fries and grills, use baffle filters, not mesh. Baffle filters spin the air through baffles so grease drops out into a tray, they're far more fire-safe (they resist flame passing through to the duct), they clean easily (dishwasher-safe metal), and they last for years. Mesh filters clog fast, hold grease right in the airflow, and are a bigger fire risk — they're really for light domestic use.
The difference that matters: | | Baffle | Mesh | |---|---|---| | How it works | Forces air through S-shaped baffles; grease centrifuges out into a tray | Traps grease in a fine metal-wool mesh in the airstream | | Fire safety | Much better — no direct path for flame; grease drains away | Poorer — grease held in the airflow path; can carry flame | | Cleaning | Easy — solid metal, dishwasher/soak | Clogs fast, hard to fully de-grease, degrades | | Life | Years | Wears out, needs replacing |
Why baffle is the commercial standard: commercial fire-safety expectations (and insurers) favour baffle filters precisely because they drain grease *away* from the airflow instead of holding it in the flame path — which matters most exactly where you fry and grill. Mesh is fine over a domestic hob with little grease; in a busy café it clogs, drips and raises the fire risk.
Switching is worth it for you. Baffle filters cost a bit more upfront but last for years and are far easier to keep degreased — and they still need washing on schedule (weekly for a busy line), same as the whole hood/duct cleaning regime. Make sure the replacements fit your hood's slots. A kitchen-equipment specialist can confirm the right baffle size for your canopy. What are other F&B folks running — all baffle now?
F&B tip: baffle filters aren't just a performance upgrade, they're often what inspectors and insurers expect on a commercial cook line for the fire-safety reason Kareem gave. If you've got mesh over a fryer/grill, switching to baffle is a sensible box to tick as well as a practical improvement. Just remember the filters are only the first stage — the full canopy and duct still needs its scheduled degrease regardless of filter type.
Not F&B but even at home I switched a greasy-hob hood from mesh to baffle-style and the difference in how easy it is to clean is night and day — the mesh ones turned into a solid grease brick you could never fully clean, the baffle ones rinse off. For a café that fries, it's a no-brainer; the mesh will be costing you time and fire risk. Buy the right size for the hood slots and keep them on a wash schedule.
