What CFM Range Hood Do I Need?
Choosing the right CFM for your range hood is essential for keeping smoke, grease, and cooking odors out of your kitchen. In this guide, we explain how much CFM you need based on your cooking style, stove type, and kitchen size.
What Is CFM in a Range Hood?
CFM stands for Cubic Feet per Minute, which measures how much air a range hood can move every minute.
The higher the CFM, the stronger the ventilation power.
A properly sized range hood helps:
• remove smoke
• eliminate cooking odors
• reduce grease buildup
• improve indoor air quality
If your hood has too little CFM, smoke and odors will escape into your kitchen.
What CFM Range Hood Do I Need?
The right CFM depends mainly on how you cook.
Here is a general guideline:
| Cooking Type | Recommended CFM |
|---|---|
| Light cooking | 300 – 400 CFM |
| Standard home cooking | 400 – 600 CFM |
| Heavy cooking | 600 – 900 CFM |
| High heat cooking | 900+ CFM |
If you frequently cook stir fry, deep fried foods, or spicy dishes, you should choose a high-CFM range hood.
This is why many homeowners who cook Asian food search for the best range hood for Asian cooking.
How Much CFM for a Gas Stove?
Gas stoves produce more heat and combustion gases than electric stoves.
Because of this, they require stronger ventilation.
A simple rule is:
100 CFM for every 10,000 BTUs of stove power.
Example:
| Stove BTU Output | Recommended CFM |
|---|---|
| 40,000 BTU | 400 CFM |
| 60,000 BTU | 600 CFM |
| 80,000 BTU | 800 CFM |
This is why many homeowners researching the best range hood for gas stoves choose models with 500 CFM or higher.
CFM Recommendations for Asian Cooking
Cooking styles such as Chinese stir fry, Korean BBQ, or wok cooking produce much more smoke and oil vapor.
This is why people often search for:
• best range hood for Asian cooking
• range hood for wok cooking
For these cooking styles, experts usually recommend:
900 CFM to 1200 CFM or more
A powerful hood captures smoke before it spreads into your kitchen.

Kitchen Size Rule
Another rule is:
1 CFM for every square foot of kitchen space
Example:
200 sq ft kitchen → 200 CFM minimum
However, cooking style usually matters more than room size.
Recommended Range Hoods for High Heat Cooking
If you cook frequently or use high heat cooking methods, a powerful ventilation system makes a huge difference.
Two excellent options include:
PQ6830 – Strong Ventilation for Heayv Cooking 1200 CFM
The Pacific PQ6830 is designed for kitchens that cook regularly.
It is ideal for households that want reliable everyday ventilation.
SC8830BS – Heavy Power for Heavy Cooking 1000 CFM
For kitchens that generate heavy smoke and grease, the SC8830BS provides strong performance.
• Asian cooking
• wok cooking
• high heat stir frying
Ducted vs Ductless Range Hood CFM
When choosing the right ventilation system, many homeowners also compare ducted vs ductless range hoods.
Ducted range hoods:
✔ vent smoke outside
✔ remove grease and odors more effectively
✔ provide stronger airflow
Ductless hoods filter air and recirculate it back into the kitchen, which may not be ideal for heavy cooking.
For the best performance, ducted range hoods are usually recommended.
Final Thoughts
Choosing the right CFM range hood helps keep your kitchen clean, fresh, and comfortable.
When selecting a hood, consider:
• your cooking style
• stove BTU output
• kitchen size
• ventilation setup
For households that cook frequently or use high heat cooking methods, models like the Pacific PQ6830 or SC8830BS provides the power needed to remove smoke and odors effectively.
