How to Choose a Range Hood (Beyond Just Style)

When designing a kitchen, range hoods often get attention for how they look—but what really matters is how they perform. A good range hood protects your home from smoke, grease, odors, and moisture. Choosing the right one isn’t just about design—it’s about functionality, efficiency, and proper installation.

Here’s what homeowners should focus on when selecting a range hood beyond appearance.

1. Ventilation Type: Ducted vs. Ductless

This is the most important decision.

Ducted Range Hoods (Best Option)

• Vents air outside the home

• Removes smoke, grease, heat, and odors effectively

• Ideal for frequent cooking

Ductless (Recirculating) Range Hoods

• Filters air and sends it back into the kitchen

• Easier to install

• Less effective for heavy cooking

Bottom line: If possible, go with a ducted system for better performance.

2. Airflow Power (CFM Rating)

CFM (cubic feet per minute) measures how much air the hood can move.

General guidelines:

• Electric cooktop: 300–400 CFM

• Gas range: 400–600+ CFM

• High-performance or professional ranges: 600–1200+ CFM

If you cook often or use high heat, higher CFM is worth it.

3. Proper Sizing Matters

Your range hood should be at least as wide as your cooktop—ideally slightly wider.

• 30” range → 30”–36” hood

• 36” range → 36”–42” hood

Wider hoods capture smoke and grease more effectively.

4. Mounting Height and Placement

Proper installation height is key for performance:

• Typically 24–36 inches above the cooktop

• Too high = less effective

• Too low = safety hazard

Follow manufacturer guidelines and local codes.

5. Noise Levels (Sones Rating)

Some powerful range hoods can be loud.

• Lower sones = quieter operation

• 1–3 sones = quiet

• 4–6 sones = moderate

• 7+ sones = loud

Look for models that balance power with noise control—especially in open-concept homes.

6. Duct Size and Layout

Even the best hood won’t perform well if the ductwork isn’t right.

Important factors:

• Use the correct duct diameter (often 6”–10”)

• Keep duct runs short and straight

• Minimize turns and bends

• Vent to the outside—not into an attic

Poor duct design reduces efficiency significantly.

7. Filters and Maintenance

Range hoods rely on filters to trap grease and particles.

Types include:

• Baffle filters (best for heavy cooking)

• Mesh filters (lighter use)

• Charcoal filters (for ductless systems)

  

Look for:

• Dishwasher-safe filters

• Easy removal and cleaning

8. Lighting and Controls

Functional lighting is important for cooking.

Consider:

• LED lighting (energy-efficient and bright)

• Multiple fan speeds

• Easy-to-use controls

9. Make-Up Air Requirements

For high-powered hoods (usually over 400–600 CFM), some building codes require make-up air systems.

This replaces the air being vented out to:

• Maintain indoor air pressure

• Prevent backdrafting from fireplaces or HVAC

This is something your contractor or HVAC professional should plan for.

Final Thoughts

Choosing a range hood isn’t just about matching your kitchen design—it’s about making sure your kitchen functions properly. Good ventilation improves air quality, protects your finishes, and makes cooking more enjoyable.

When in doubt, focus on:✔ Proper ventilation (ducted if possible)✔ Correct sizing and CFM✔ Quality installation

Style matters—but performance matters more.
