3 Ways to Cut Your Range Hood / Exhaust Fan Energy Bill
- 🌱
Use the lowest effective speed setting — low speed uses about 40% less energy than high while still capturing most cooking vapors.
- 💡
Clean or replace the grease filter monthly to maintain proper airflow and prevent the motor from working harder.
- ⚡
Turn the hood on a few minutes before cooking to establish airflow, which is more efficient than trying to clear a smoky kitchen after.
The fan motor draws a brief startup surge of about 400–500W before settling to its running wattage.
