Frequently Asked Questions

1.What is the purpose of an exhaust fan?

Exhaust fans remove stale air, moisture, odors, and pollutants from enclosed spaces, improving ventilation and indoor air quality.

2.What is the difference between a ventilation fan and an exhaust fan?

Both terms, exhaust and ventilation fan, are used interchangeably; these products are used to pull out stale air, moisture, heat, and odors from enclosed spaces and expel them outdoors. Atomberg Exhaust Fans not only remove unwanted air but also enhance overall airflow in your home. Powered by energy-efficient BLDC motors and designed for continuous, quiet operation, they keep your spaces fresh, comfortable, and well-ventilated throughout the day.

3.Do exhaust fans cool rooms?

Exhaust fans don't cool a room the way ceiling or pedestal fans do—they don't circulate cool air. Instead, they help maintain a comfortable environment by removing excess heat, humidity, odors, and smoke, especially in kitchens and bathrooms. By expelling warm and stale air, they make the space feel fresher and less stuffy, indirectly contributing to a cooler and more breathable atmosphere.

4.Where is the best place to put an exhaust fan?

Place exhaust fans near sources of heat or humidity— in bathrooms near showers, kitchen or at the ceiling's highest point for efficient ventilation.

5.Can an exhaust fan run 24 hours?

Yes — if the fan is designed and rated for continuous operation. Atomberg Exhaust Fans, powered by advanced BLDC motor technology, are built for long-lasting performance and energy efficiency. They can run continuously for extended hours without overheating or consuming excess power, making them ideal for spaces that require consistent ventilation.

6.Can I install an exhaust fan myself?

Yes, wall- or window-mounted exhaust fans can often be installed using basic tools and a few simple steps. However, for safety and optimal performance, it's always recommended to seek help from a qualified electrician.

7.What is the best exhaust fan for a bathroom?

The best exhaust fan for a bathroom is one that offers strong air delivery, quiet operation, and resistance to moisture. It should effectively remove humidity, odors, and steam to keep the space fresh and mold-free. Look for fans with rust-resistant materials, efficient motors, and low noise levels to ensure reliable, long-term performance in humid environments.

8.Can I use the same exhaust fan for the kitchen and bathroom?

You can use the same exhaust fan for both the kitchen and bathroom only if the room sizes and ventilation needs are similar. Bathrooms up to 200 square feet can use a 150 mm fan, which provides sufficient airflow for humidity and odor control. Larger spaces like kitchens up to 380 square feet require a 200 mm fan, while standard kitchens up to 550 square feet need a 250 mm fan for effective removal of smoke, heat, and grease. In short, the same fan can't serve both spaces efficiently unless their size and ventilation requirements are the same—always choose the fan size based on the area of the room.

9.What is the CMH rating in exhaust fans?

CMH (Cubic Metres per Hour) is a measure of how much air an exhaust fan can move in one hour. It indicates the fan's air suction or ventilation capacity. A higher CMH rating means the fan can expel more air, resulting in faster and more efficient removal of smoke, odor, heat, and moisture. Choosing the right CMH rating based on your room size ensures optimal ventilation and fresh, breathable air.

10.What noise level should I expect from an exhaust fan?

Quality fans operate quietly, often around 55 dB. Look for low-noise or silent models if you're installing in bathrooms.

11.What are backdraft shutters or backflaps, and why are they important?

Backdraft shutters or backflaps prevent insects or dust from entering when the fan is off.

12.Do exhaust fans come with humidity sensors?

No, the exhaust fan needs to be manually switched on when the humidity is high.

13.How do I maintain an exhaust fan?

To keep your exhaust fan running efficiently, clean it regularly. Remove the front grill and wipe it with a soft, damp cloth to clear dust and grease buildup. Check for any obstructions and ensure the motor runs smoothly without unusual noise. Regular cleaning not only improves air circulation but also extends the fan's lifespan and maintains optimal performance.

14.Do exhaust fans help prevent mold and mildew?

Yes. By reducing excess humidity, they prevent conditions where mold and mildew typically thrive, especially in poorly ventilated bathrooms.

15.How long do exhaust fans typically last?

With proper maintenance, a quality exhaust fan can last 5–10 years or more, especially models with durable motors and corrosion-resistant parts. However, Atomberg products come with a 1+1-year warranty.

What Are Exhaust Fans?

Exhaust fans are ventilation devices that remove stale air, moisture, smoke, and odors from indoor spaces. Commonly used in kitchens and bathrooms, they improve air quality, prevent mold, and maintain a fresh environment. They are available in various types, offering features such as low to high noise levels (measured in decibels), varying energy efficiency ratings, and humidity control, allowing users to choose based on comfort and power consumption needs.

How Does an Exhaust Fan Work?

An exhaust fan works by using a motor to rotate its blades, which pull stale, hot, or humid air from inside a room and push it outside through a wall, window, or duct. This creates slight negative pressure inside the space, allowing fresh air to naturally enter through openings like doors, windows, or vents. As a result, it helps remove odors, moisture, and heat, improving overall air quality and ventilation.

Different spaces demand different ventilation solutions. Atomberg offers a range of exhaust fans designed to suit every need:
