Kitchen Ventilation Buying Guide

A proper kitchen ventilation system is essential for maintaining clean air, controlling odors, and removing heat, smoke, and grease from your cooking area. Whether you’re replacing an old range hood or upgrading your entire kitchen, choosing the right ventilation system ensures both functionality and a stylish focal point.

This guide will walk you through the main types of kitchen ventilation systems, their key features, pros and cons, and what to consider before buying. 


 1. Ventilation Types

Wall Mount Hoods

Wall Mount Hoods

Mounted to: The wall above a cooktop or range

Best For: Standard kitchen layouts with the cooktop against a wall


Pros

  • Bold, stylish focal point in the kitchen
  • Excellent ventilation performance and power options
  • Available in many styles, from modern to traditional

Cons

  • Requires ductwork through the wall or ceiling
  • Takes up more visual space than other options
  • May require removing cabinets to install


Island Hoods

Island Hoods

Mounted to: The ceiling above a cooktop installed on an island

Best For: Open-concept kitchens with cooking islands

  • Wide variety of designer finishes and shapes

  • Modern, high-end visual appeal

Cons

  • Requires ceiling-mounted ductwork (more complex installation)
  • Can obstruct sightlines in open kitchens

  • Typically more expensive than wall-mount models

Under-Cabinet Range Hoods

Under-Cabinet Range Hoods

Mounted to: The underside of cabinetry above your cooktop

Best For: Traditional Kitchen layouts with cabinetry over the range


Pros

  • Compact, space-saving design
  • Simple installation, especially in existing cabinetry

  • Often the most affordable hood type

Cons

  • Compact, space-saving design
  • Simple installation, especially in existing cabinetry

  • Often the most affordable hood type

Hood Liners

Hood Liners (Insert Hoods)

Mounted to: Inside a custom-built hood enclosure or cabinetry

Best For: Custom kitchen designs where aesthetics are a priority


Pros

  • Blends seamlessly into custom cabinetry or mantels
  • Hidden design offers a clean, built-in look

  • Flexible size and power options for personalized setups

Cons

  • Requires a custom enclosure (increased cost/design work)
  • Maintenance can be trickier if space is tight

  • Installation can be more involved

Downdraft Ventilation

Downdraft Ventilation

Mounted to: Behind or next to the cooktop (retractable or built-in)

Best For: Minimalist kitchens or islands where the overhead hoods compatible


Pros

  • Retractable design is nearly invisible when not in use
  • Doesn’t obstruct sightlines or lighting

  • Great solution for island cooktops with no overhead clearance

Cons

  • Less effective at removing smoke/grease compared to overhead systems
  • Installation can be complex and may reduce cabinet space

  • Limited airflow power (not ideal for high-heat cooking)

 2. Sizing and Installation Requirements

Before making your decision, make sure it fits in your kitchen setup.


Standard Ventilation System Sizes

30 inches: Matches most standard cooktops and ranges
36 inches or larger: Recommended for larger cooktops or professional-style ranges
Pro Tip: Ideally, the hood should be the same width or up to 6 inches wider than your cooktop (e.g., a 30" cooktop pairs well with a 36" hood)


Mounting Height Requirements (recommended mounting height above cooktop)

Under-Cabinet Hood: 20" - 24"

Wall Mount Hood: 24" - 30"

Island Hood: 30" - 36"

Downdraft Vent: Flush with cooktop surface or behind unit


Measure your space
Always measure width, height, and depth of your available space and surrounding area.


Connections and Requirements

Most hoods require a 120V grounded outlet, located in the cabinet above or behind the unit
Some high-end or smart hoods may need hardwiring or special access—check the spec sheet before installation


 3. Key Features to Consider

When comparing range hoods, pay attention to the following features:

Airflow Power (CFM)

Measured in Cubic Feet per Minute (CFM) - indicates how much air the hood can move

Typical Recommendations:

  • 250 - 400 CFM for light cooking
  • 400 - 700 CFM for daily cooking or small gas ranges
  • 700+ CFM for high-output gas ranges or heavy frying

Noise Level

Measured in sones - lower numbers are quieter
Look for multi-speed fan settings so you can adjust power/noise as needed


Lighting

Most hoods feature built-in LED or halogen lighting
Look for adjustable brightness settings and easy bulb replacements


Filter Type

Mesh filters: Easy to remove and dishwasher-safe
Baffle filters: Durable and more efficient for grease capture (ideal for heavy cooking)
Charcoal filters: Used in ductless models to absorb odors (need regular replacement)
