Is a range hood the same as an exhaust fan?
A range hood is the complete appliance above the cooking surface. Its canopy, filters and air-moving system work together. “Hood fan” often means the fan or blower inside that appliance, although shoppers also use the term for the whole hood. A separate kitchen exhaust fan moves room air and does not necessarily include a cooking canopy or grease filters.
The important shopping question is what equipment you are replacing and where the air will go. A new motor for an existing hood, a complete under-cabinet hood and a wall-mounted room fan are different purchases. Check the model number and installation instructions before ordering a replacement.
Range hood, hood fan and room exhaust fan compared
| Term | What it usually means | Main purchasing check |
|---|---|---|
| Range hood | A cooking-ventilation appliance with a capture area, filtration and an air-moving arrangement | Cooking appliance compatibility, fit and ventilation design |
| Hood fan or blower | The air-moving component; sometimes shorthand for the complete hood | Whether you need a model-approved part or a whole appliance |
| Kitchen exhaust fan | A separate fan for exhausting room air | Its intended use, location and connection to the ventilation plan |
A canopy positioned over the range captures emissions near their source. HVI describes a separate kitchen exhaust fan as another form of ventilation, which may be used with a hood; it is not automatically the same capture arrangement. Source: HVI guidance on ventilating living areas.
Ducted vs ductless range hoods
A ducted hood sends the extracted air outdoors. A ductless or recirculating hood passes air through its specified filters and returns it to the room. HVI notes that recirculation does not remove cooking moisture and offers limited odor control. A higher fan setting does not turn recirculation into outdoor exhaust.

Check whether the exact hood supports the installation you need and which parts are required. Do not assume that every ducted hood can be converted. If outdoor ducting is unavailable, have the cooking appliance and ventilation requirements reviewed before selecting equipment.
Can I use a regular exhaust fan instead of a range hood?
Do not assume a room fan is a direct substitute. Check whether the proposed equipment is designed for the intended cooking application, how emissions will be captured and what the appliance manufacturer requires. A fan on another wall can exhaust air without providing the same arrangement immediately above the pans.
If you are replacing a broken hood, first record the existing model, cabinet opening, outlet location and duct dimensions. If only a component has failed, ask about an approved replacement part. A larger generic fan is not automatically a compatible repair.
Two examples of complete under-cabinet hoods
- ZLINE 623-30, 30-inch model: a ducted under-cabinet hood with a published maximum of 600 CFM.
- Forno Bari FRHUC5255-30: a 30-inch under-cabinet hood rated up to 400 CFM.
These examples illustrate complete hoods rather than replacement fan parts. Their ratings do not establish that either is suitable for every 30-inch range. Sources: ZLINE model specifications and Forno model specifications.
What should the installer check?
Provide the cooktop and hood manuals together. Ask the installer to confirm capture coverage, mounting clearances, the route outdoors, duct dimensions, electrical requirements and any required provision for replacement air.
For example, the ZLINE 600 Series manual calls for metal ducting, prohibits plastic ventilation and requires exhaust to terminate outdoors. It also specifies the model's duct dimensions and mounting clearances. Do not substitute a generic PVC-duct recommendation for the selected hood's instructions.

Should you compare CFM or brand next?
Once the installation type is clear, use our CFM sizing guide to understand airflow planning. Then use the range hood brand comparison to compare compatible models.
