How long does a kitchen extractor hood last?
Typical
12 years
Range
10–15 years
A domestic extractor hood typically lasts 10–15 years. The motor is the life-limiting part, and grease is what kills it — saturated filters make it work harder and become a fire risk (commercial kitchens have statutory cleaning regimes for exactly this reason).
What decides it
- Washing or replacing grease filters on schedule
- Recirculating models: changing carbon filters
- Duct length and bends — a struggling motor is a short-lived motor
When to replace rather than repair
Motor failure past year 10 is the natural replacement point; lamps, filters and switches are consumables.
Typical ranges from manufacturer guidance and industry surveys — individual machines vary with use and care. General information, not advice on a specific appliance.
