How to Choose the Right Slideout or Undermount Rangehood

Space-Saving Rangehood Solutions

Not every kitchen has the wall space or ceiling height for a full canopy rangehood. Slideout and undermount rangehoods are designed to mount neatly under an overhead cabinet directly above the cooktop, providing effective extraction without taking up visual space in the kitchen. They're a popular choice for apartment kitchens, galley layouts, and renovations where a lower-profile solution is preferred.

This guide covers the key differences between slideout and undermount rangehoods, what features to look for, and how to choose the right model. You can compare all rangehood types in our full rangehood buying guide.

Slideout Rangehoods

A slideout rangehood (also called a retractable rangehood) mounts inside or underneath an overhead cabinet. The extraction unit sits inside the cabinet when not in use. When cooking, you slide a panel outward and downward to extend the extraction surface over the cooktop. This design keeps the rangehood completely hidden when not in use, which suits kitchens where a clean, minimalist look is important.

Undermount Rangehoods

An undermount rangehood (also called an undercupboard rangehood) mounts in a fixed position on the underside of an overhead cabinet. Unlike a slideout model, it doesn't retract and is always visible below the cabinet. It's a simpler installation than a slideout and typically offers a wider extraction surface for a given cabinet width. Undermount rangehoods are a practical, affordable choice for most kitchen installations.

Key Features to Look For

Width

Choose a rangehood that is the same width as your cooktop or slightly wider. Common widths are 60 cm and 90 cm, matching standard cooktop widths. A rangehood narrower than the cooktop will not capture all rising steam effectively.

Airflow Rating (m³/hour)

Slideout and undermount rangehoods are generally less powerful than full canopy models due to their compact size. Look for the highest airflow rating within your budget.

• Under 400 m³/h: Suitable for light cooking, electric or induction cooktops, and smaller kitchens.
• 400 to 700 m³/h: Suitable for everyday family cooking above an electric, ceramic, or moderate-use gas cooktop.
• 700 m³/h and above: Recommended for gas cooktops and heavier cooking.

For gas cooktops with a wok burner or high-output burners, a canopy rangehood with a higher airflow rating is generally more appropriate than a slideout or undermount model.

Ducted vs. Recirculating

As with all rangehoods, ducted installation (externally vented) is more effective than recirculating (filtered and returned to the kitchen). Both options are available in slideout and undermount models. Ducted is recommended where possible; recirculating is a practical alternative for apartments or kitchens where external ducting is not possible.

Filter Type

Slideout and undermount rangehoods use grease filters to capture airborne grease particles. Aluminium or stainless steel mesh filters are standard and washable. For recirculating models, carbon filters are also required to absorb odours and need to be replaced every three to six months.

Fan Speed Settings

Look for at least two to three speed settings. A minimum speed for gentle cooking and a maximum speed for heavy extraction are the essentials. Some models include a boost function.

Noise Level

Compact rangehoods can be noisier than larger canopy models at equivalent airflow settings due to smaller fans running at higher speeds. Check the noise rating (dB) of any model you're considering, particularly if the kitchen is open to a living or dining area.

Controls and Lighting

Most modern models include push-button or touch controls for fan speed and lighting. LED lighting is preferred for energy efficiency and longevity. Lighting quality matters as rangehoods installed under overhead cabinetry are often the primary task lighting for the cooktop.

What to Expect at Different Price Points

Budget (Under $250)

Entry-level slideout and undermount rangehoods provide basic extraction suitable for light cooking. Expect two speed settings, basic filters, and standard lighting.

Mid-Range ($250 to $600)

Mid-range models offer better airflow, LED lighting, stainless steel mesh filters, additional speed settings, and better build quality. Most households will find an excellent model in this range.

Premium ($600 and Above)

Premium models deliver higher airflow for compact units, better noise management, touch controls, and refined finishes. Worth considering for a high-quality kitchen renovation.

Frequently Asked Questions

What is the minimum cabinet depth needed for a slideout rangehood?

Most slideout rangehoods require a cabinet depth of at least 300 to 350 mm for the unit to sit inside. Check the specifications of your chosen model and measure your existing overhead cabinet before purchasing.

Can I use an undermount rangehood above a gas cooktop?

Yes, but choose a model with an adequate airflow rating (ideally 600 m³/h or more) and ensure it is externally ducted rather than recirculating. Gas cooking produces combustion gases that are best vented outside rather than filtered and recirculated.

How often do I need to replace carbon filters?

Carbon filters in recirculating models should be replaced every three to six months depending on cooking frequency. Heavy cooking may require replacement every two to three months. Replacing filters on schedule maintains effective odour removal performance.
