Baffle vs. Mesh Filters: What Every Homeowner Should Know

Your hood’s filters are its first line of defense against grease. Knowing which type you have — and how to care for it — protects your airflow and your kitchen.

Baffle filters

Baffle filters are the heavy, interlocking metal panels found in most premium and pro-style hoods. They channel grease down and away using a series of baffles, are highly effective, and are built to last — but they still need regular degreasing to keep airflow strong.

Mesh (aluminum) filters

Mesh filters are layered aluminum screens common in many standard and some designer hoods. They trap grease across the mesh, which means they clog faster and need cleaning more often. Avoid harsh dishwasher cycles, which can oxidize and degrade aluminum mesh over time.

How to care for them

Whatever type you have, the goal is the same: keep grease from hardening in the filter and choking your airflow.

  • Degrease every 1–3 months for busy kitchens
  • Soak in a proper degreasing solution — not just dish soap
  • Skip aggressive dishwasher cycles for aluminum mesh
  • Dry fully before reinstalling
  • Have them professionally treated alongside your annual cleaning

When to replace

Baffle filters rarely need replacing if maintained. Mesh filters that are bent, torn, or permanently darkened should be replaced. If you’re unsure, we’ll tell you honestly during a visit and point you to the correct filter for your hood.

Quick answers

Common questions

Are baffle filters better than mesh?

For grease capture and longevity, baffle filters generally outperform mesh — but both work well when kept clean.

Can I put filters in the dishwasher?

Baffle filters usually tolerate it; aluminum mesh can oxidize and degrade. A proper degreasing soak is gentler and more thorough.
