Most kitchen crews clean their hood filters. Fewer replace them. But here’s the truth: filters don’t last forever. Over time, even if you’re washing them regularly, the grease, wear, and metal fatigue stack up. So how do you know when it’s time to replace your filters instead of just cleaning them again? Let’s break it down.
Signs Your Filters Need Replacing, Not Just Cleaning
1. Warped or Bent Frames
If your filters are bent out of shape, they won’t seat properly – and that means grease is leaking around them, not through them.
2. Rust or Corrosion
Filters are built for heat and moisture – but not forever. Rust compromises airflow and increases fire risk.
3. Stubborn Grease That Won’t Come Out
If you’ve soaked and scrubbed your filters and they’re still sticky or clogged, it’s time.
4. Visible Damage or Loose Mesh
Loose panels or shifting baffles = reduced filtration. These are no longer doing their job safely.
How Often Should You Replace Hood Filters?
There’s no one-size-fits-all answer, but we typically recommend:
- High-volume kitchens (fryers, BBQ): Monthly
- Medium-volume restaurants: Every 3 months
- Light-use kitchens: Annually
We inspect yours and give you the honest call.
