What is a range hood?

A range hood is a kitchen appliance that removes airborne grease, smoke, odors, heat, and steam produced during cooking. It uses a fan to pull air through a filter and then either vents it outside (ducted) or recirculates it back into the kitchen after filtering (ductless).

How does a range hood work

  • The fan creates suction that draws cooking byproducts upward into the hood.
  • In a ducted system, the air travels through ductwork and exits through an exterior wall or roof.
  • In a ductless system, air passes through a charcoal filter that traps odors and then returns to the kitchen (Fred’s Appliances).

Key components of a range hood system

  • Fan motor (rated in CFM – cubic feet per minute)
  • Grease filter (mesh or baffle, washable)
  • Charcoal filter (for ductless models, replaced every 3–6 months)
  • Ductwork (for ducted models)
  • Back-draft damper (prevents outside air from entering)
The trade-off

Ducted hoods are more powerful and effective, but they require planning for duct size, minimizing bends, and a short straight run. Ductless hoods are simpler to install but less effective at removing heat and moisture — a critical difference if you cook more than twice a week.

Do range hoods need to be vented outside?

No — but it depends on your cooking habits and local codes. Ducted venting to the outside is the most effective method for removing moisture and indoor pollutants. For serious cooks, it’s the clear winner. However, ductless hoods recirculate air through a charcoal filter and are acceptable in some setups, especially apartments or spaces where ductwork is impractical.

Is ductless (recirculating) range hood a viable option

  • Viable for light cooking (boiling, reheating) and small spaces where ductwork cannot be added.
  • Ineffective for removing humidity, so kitchens in humid climates or with frequent heavy cooking may experience mold and moisture issues.
  • Charcoal filters must be replaced every 3–6 months to maintain performance (Proline Range Hoods).

Why building codes often require outside venting for gas ranges

  • Gas ranges produce carbon monoxide, nitrogen dioxide, and other combustion byproducts.
  • Most U.S. building codes mandate outside venting for gas ranges to maintain indoor air quality (Robalm Living).
  • Ductless hoods do not remove combustion gases — they only filter particulates and odors.
Why this matters

Cooking with gas without proper exhaust increases the risk of respiratory issues. The U.S. Consumer Product Safety Commission (CPSC) has warned about the indoor air quality impact of gas stoves, and a ductless hood simply doesn’t meet the ventilation standard required to mitigate those risks.

Ducted vs. Ductless Range Hoods: Which one to buy?

Five key differences separate the two systems. One pattern: the more you cook, the more the ducted option pulls ahead.

Feature Ducted Ductless
Venting method Exhausts air outside Recirculates filtered air indoors
Effectiveness on smoke & grease High – physically removes them (Whirlpool) Moderate – only captures particles, not heat or moisture
Installation complexity Requires ductwork, possibly a new circuit Simple plug-in, no ductwork needed (Wurth Louis & Company)
Upfront cost (hood + install) $350–$1,200+ $100–$600
Lifespan 10–15 years 5–8 years

Pros and cons of ducted range hoods

Upsides

  • Superior air quality – polluted air is physically expelled outside (Robalm Living)
  • Quieter operation for the same CFM class
  • Better at removing heat and steam
  • Longer motor life (motor doesn’t work against filter clogging)

Downsides

  • Higher installation cost – $100–$1,000 depending on complexity (Proline Range Hoods)
  • Requires professional ductwork planning and electrical work
  • Not feasible in apartments without existing ducts
  • May require makeup air in tight homes (Robalm Living)

Pros and cons of ductless range hoods

Upsides

  • Quick, low-cost installation – $100–$300 (Proline Range Hoods)
  • Can be installed anywhere there is a power outlet
  • Good for light cooking and small kitchens
  • No structural modifications to the home

Downsides

  • Does not remove heat, humidity, or combustion gases
  • Must replace charcoal filters every 3–6 months ($25–$60 each) (Proline Range Hoods)
  • Loud at high fan speeds – typically 5–10 sones
  • Shorter lifespan due to motor wear from recirculating greasy air

Which type of range hood is best?

Three major form factors dominate the market. The one you choose depends on your kitchen layout and cooking frequency.

Wall mounted vs. island vs. under-cabinet vs. canopy

  • Wall mounted hoods – attached to the wall above the cooktop, usually vented through the wall or roof. Best for serious cooks with a wall behind the stove.
  • Island hoods – suspended from the ceiling above a kitchen island. More expensive to install ($300–$500 for labor alone, per Proline Range Hoods).
  • Under-cabinet hoods – fit beneath a cabinet above the cooktop. Good for small to medium kitchens; installation runs $200–$400 (Proline Range Hoods).
  • Canopy (or chimney) hoods – freestanding or sliding into a cabinet, often with higher CFM ratings for professional-style cooking.

Key criteria: CFM rating, noise level, material, size

  • CFM rating: For a gas range, you need at least 100 CFM per burner (typical 600–900 CFM for a 5-burner stove). For induction or electric, 400–600 CFM is sufficient.
  • Noise level: Measured in sones – 3 sones is quiet conversation, 10 sones is a blender. Aim for 6 sones or less at normal cooking speed.
  • Size: The hood should be at least as wide as the cooktop (usually 30″ or 36″).
  • Material: Stainless steel is standard for durability and cleanability.
The upshot

For anyone who cooks more than twice a week, a wall-mounted ducted hood with at least 600 CFM is the only option that removes enough moisture and heat. Under-cabinet ductless hoods are fine for occasional boiling or takeaway, but they will leave steam and grease film on cabinets over time.

What is the average cost of a range hood?

Five price layers define the market: hood unit alone, ductwork materials, installation labor, electrical work, and ongoing filter replacements.

Cost breakdown: hood unit vs. installation vs. ductwork

  • Hood unit: $150–$650 for most under-cabinet and wall-mounted models. Premium models with smart controls or commercial-grade stainless exceed $1,000.
  • Installation labor: A typical installer charges about $85 per hour plus a trip fee of $50–$100 (Proline Range Hoods).
  • Ductwork: Adding new ducting through the wall or roof can add $200–$500. Ductless systems need none.
  • Electrical: If a new circuit is needed, an electrician costs $150–$400.

Price range by type: basic, mid-range, premium

Type Price Range (hood + install)
Basic under-cabinet ductless $150–$400
Mid-range wall-mounted ducted $500–$1,000
Premium ducted (island or commercial) $1,000–$2,500+

What this means: The upfront saving of a ductless hood ($100–$300 vs. $500–$1,200) is often eaten up by higher lifetime costs from frequent filter replacements and shorter lifespan. A ducted hood may cost double upfront but lasts 10–15 years instead of 5–8.

Do you need an electrician to install a range hood?

It depends on whether the model is hardwired or plug-in, and whether a new circuit is required.

When a hardwired installation requires a licensed electrician

  • If the hood is hardwired (wires connected directly to the home’s electrical system) or requires a new dedicated circuit, most local codes mandate a licensed electrician (Proline Range Hoods).
  • Ducted hoods are almost always hardwired, adding $150–$400 for an electrician visit.

Plug-in models may not need electrician

  • Many ductless hoods come with a standard plug and can be installed by a handy homeowner using an existing outlet.
  • Wall-mounted ducted hoods with a plug are rare but exist – check the manufacturer specs.

What is the average lifespan of a range hood?

Two different life expectancies emerge depending on the venting type.

Lifespan of ducted vs ductless models

  • Ducted hoods: 10–15 years average. The motor runs cleaner because grease-laden air is expelled, not recirculated.
  • Ductless models: 5–8 years average. The motor wears faster from constant exposure to grease and cooking particles, even with regular filter changes (Proline Range Hoods).

Signs it is time to replace

  • Fan becomes increasingly loud or rattles even after cleaning
  • Smoke and odors linger despite the hood running
  • Grease filters are damaged or deformed
  • For ductless: the motor runs but airflow feels weak (filter clogged or motor failing)

What’s clear and what’s not

Confirmed facts

  • Ducted hoods move air outdoors and are more effective at removing heat and moisture (Whirlpool)
  • Most U.S. building codes require outside venting for gas ranges (Robalm Living)
  • Ductless hoods require charcoal filter replacement every 3–6 months (Proline Range Hoods)

What’s unclear

  • Exact percentage of home fires prevented by using a range hood vs not
  • Whether ductless hoods provide any real health benefit for sensitive groups

“ASHRAE Standard 62.2 requires residential kitchens to have local mechanical exhaust ventilation of at least 100 CFM for kitchens with a cooktop.”

ASHRAE Standard 62.2 (Ventilation and Acceptable Indoor Air Quality in Residential Buildings)

“We know that cooking, especially frying and grilling, can produce levels of fine particulates that exceed outdoor limits. A ducted range hood that vents to the outside is the most effective way to reduce exposure.”

U.S. Consumer Product Safety Commission (CPSC) – Indoor Air Quality and Cooking Emissions

“Ducted hoods can deliver superior air quality because polluted air is physically expelled outside. Ductless systems incur periodic filter replacement but do not remove humidity or combustion gases.”

Robalm Living – Ducted vs. Ductless Range Hoods: A Head-to-Head Comparison

Summary: Choosing a ductless range hood to save money on installation may feel like a short-term win, but for anyone who cooks more than twice a week, the trade-off is higher humidity, lingering odors, shorter appliance life, and a greater risk of indoor air pollution. For the home cook in the U.S., the choice is clear: invest in a ducted system from the start, or face a replacement bill and an uncomfortable kitchen in under a decade.

Frequently asked questions

What size range hood do I need for my kitchen?

Your hood should be at least as wide as your cooktop, and its CFM rating should match your cooking surface. For a gas range, aim for 100 CFM per burner; for electric/induction, 400–600 CFM is usually sufficient.

Can I install a ductless range hood in a small apartment?

Yes – ductless hoods require only a power outlet and no ductwork, making them a practical choice for apartments where structural modifications are not permitted. Just be aware that they do not reduce humidity.

How often should I replace the charcoal filter in a ductless hood?

Replace it every 3 to 6 months, or after about 120 hours of cooking (Proline Range Hoods). Filters cost $25–$60 each.

Does a range hood need to be larger than my cooktop?

Ideally, yes – a hood that is 3–6 inches wider than the cooktop on each side captures more rising smoke and steam. At minimum, match the cooktop width.

Are ducted range hoods hard to install?

Ducted installation can take 2–4 hours and requires cutting ceiling or wall openings for ductwork. Professional installation is strongly recommended (Proline Range Hoods).

What CFM is best for a gas stove?

For a typical 5-burner gas stove, 600–900 CFM is recommended. Higher than 900 CFM may require a makeup air system to prevent negative pressure in the home, especially in newer airtight houses.

Do range hoods reduce cooking smells completely?

Ducted hoods can eliminate 99% of cooking odors if properly sized and installed. Ductless hoods reduce odors significantly but do not remove them entirely, and they lose effectiveness as the charcoal filter ages.
