Exhaust Fans: Kitchen and Bathroom Types, Window, Duct and Ceiling Models, Sizes and Airflow, Noise and Installation
Exhaust fans remove steam, smoke, smells and damp air from kitchens, bathrooms and utility rooms, which protects paint, cabinets and health. The right fan matches the room volume, the place it vents to and the noise level you can accept. Window and wall fans are the common type, and duct and ceiling fans suit false ceilings. This guide covers types, sizing, installation and indicative prices. For sizing help, see our exhaust fan size guide, and for kitchen hoods, exhaust hoods.
Types of exhaust fan
Choose by where the air must go.
| Type | Best for | Note |
|---|---|---|
| Window or wall fan | Kitchens, bathrooms with outer walls | Most common, needs a hole |
| Duct exhaust fan | False ceilings, inner bathrooms | Needs a duct to outside |
| Ceiling ventilation fan | Inner rooms | Quiet, slim |
| Slim BLDC fan | Low power use | Imported models |
| Kitchen hood | Over the hob | Captures smoke and grease |
Sizing
Choose airflow for the room volume. Kitchens need more air changes than bathrooms. See the exhaust fan size guide.
Noise and power
Larger, slower fans are quieter. BLDC models use less power. Check the noise rating.
Shutters and backdraft
A shutter or jali keeps insects and wind out and stops backdraft when the fan is off.
Installation
Cut a clean hole, seal around the fan and vent outside, never into a ceiling void. Use a licensed electrician. See electrical fittings.
Kitchen hoods
For cooking smoke, a hood over the hob works better than a fan alone. See exhaust hoods and kitchen hoods.
