How to Choose the Right Undermount Rangehood

What Is an Undermount Rangehood?

An undermount rangehood (also called a built-in or integrated rangehood) is installed inside an overhead kitchen cabinet, completely hidden from view when not in use. Only the grease filters and controls are visible on the underside of the cabinet. An undermount rangehood is the most discreet extraction solution available and is ideal for kitchens where a clean, minimalist aesthetic is the priority.

For a comparison of all rangehood types, see our complete rangehood buying guide. For slideout models that also hide inside a cabinet but extend when in use, see our slideout rangehood guide.

Undermount vs Slideout: Key Difference

A slideout rangehood has a telescoping extraction panel that pulls out from the cabinet during cooking and retracts when not in use. An undermount rangehood has a fixed extraction surface on the underside of the cabinet with no moving parts — it is always in the same position but hidden inside the cabinet body. Undermount models are fully concealed and have a cleaner look when viewed from outside the cabinet.

Key Features to Look For

Airflow Rating (m³/hour)

Undermount rangehoods are typically more compact than canopy or slideout models, which can limit maximum airflow. For a standard electric or induction cooktop, 400 to 600 m³/h is adequate. For gas cooktops, prioritise the highest airflow model available in your cabinet size. Confirm the model's airflow rating suits your cooktop type before purchasing.

Width and Cabinet Compatibility

Undermount rangehoods must be matched to the width and internal depth of the overhead cabinet they're installed into. Common widths are 60 cm and 90 cm. Always check the model's installation dimensions against your cabinet specifications before purchasing.

Ducted vs Recirculating

Ducted installation vents extracted air outside via a duct through the cabinet and wall or ceiling. This is the most effective option. Recirculating models filter air through grease and carbon filters and return it to the kitchen. Recirculating is required where external ducting is not possible. For gas cooktops, ducted extraction is strongly recommended.

Motor Location

Some undermount rangehoods are designed for remote motor installation — the motor is installed separately in the roof cavity or outside the building, with only the extraction grille inside the cabinet. Remote motors operate more quietly in the kitchen and can achieve higher airflow than internal motors. Worth considering in premium kitchen builds where noise is a priority.

Grease Filters

Stainless steel mesh grease filters are standard and dishwasher safe on most models. Check the filter area — a larger filter area captures more grease before needing cleaning. A filter saturation indicator alerts you when cleaning is due.

Controls

Undermount rangehood controls are typically located on the visible underside of the unit. Touch controls with LED speed indicators are standard on most current models. Some models can be controlled remotely via a wall switch or smart home system.

LED Lighting

LED downlights on the underside of the unit illuminate the cooktop. LED is standard on most current undermount models and provides better light quality than older halogen options.

What to Expect at Different Price Points

Mid-Range ($400 to $1,000)

Mid-range undermount rangehoods deliver reliable extraction performance, LED lighting, washable filters, and concealed installation. Most households will find a practical model in this range.

Premium ($1,000 and Above)

Premium models offer higher airflow, quieter operation, remote motor options, and the most refined control interfaces suited to high-specification kitchen renovations.

Frequently Asked Questions

Can I install an undermount rangehood in any overhead cabinet?

Not all cabinets are suitable. The cabinet must have sufficient internal depth and height to accommodate the rangehood unit, and there must be a clear path for the duct to exit the cabinet and reach the outside. Check the installation requirements of your chosen model carefully against your cabinet dimensions.

Are undermount rangehoods as effective as canopy models?

Canopy rangehoods generally achieve higher airflow due to their larger motors and wider capture area. Undermount models are suitable for standard cooking on electric, ceramic, and induction cooktops. For heavy gas cooking with a high-output wok burner, a canopy rangehood typically delivers more effective extraction.
