How do you choose the Best Exhaust Fan in India?

An exhaust fan is ideally a small element in your home, but choosing the right is extremely important. We don’t tend to give it priority or can I say we are totally unaware about the buying process? Buying an exhaust fan does need a whole thought process to it.

Ultimately, we all want a clean and healthy environment at home, right?  So here are the factors you must consider before buying the best exhaust fan for your home.

Number of Blades

The idea behind installing an exhaust fan is to remove foul air and bad odour from your bathroom and kitchen. Exhaust fans come with blades ranging from 2-5.  An ideal exhaust fan is equipped with four blades. They would operate well even at low RPM. These blades are capable of eliminating all the unwanted odour, humidity and moisture. They also function in reduction of chemicals and other harmful elements. As a result, you will enjoy adequate ventilation and improved air quality at home.

Best Brands for Exhaust Fan

With the increasing demand of exhaust fans, it is becoming a booming market. So many brands are coming with exceptional features to attract customers. However, there are a few brands which don’t just deliver good results but also a premium appeal to make your bathroom and kitchen look ultra-modern. We did an in-depth research on the best exhaust fans in India only to get you more aware about them. All the above listed ones are brands with exceptional features and performance. Bajaj, Usha, Luminous and Havells are surely the best brands for exhaust fans.

Build Material of Blades

It is a common misconception of kitchen exhaust fans having steel or aluminum blades. Most exhaust fans nowadays come with plastic blades to make it look more stylish and sleeker. Plastic blades ensure durability and are also corrosion resistant. To top it all, they are extremely cheap to even get it replaced.


In earlier times, exhaust fans were very simple looking. They had broad grills for ventilation. However, now the exhaust fan market has come with an exclusive range. Manufacturers have started focusing on the appearance as well so as to make it look aesthetically pleasing. No harm in buying a good-looking model, right? Since you are getting one installed inside your house, take a close look at the color and design of it. Find a color which goes well with your interiors. Models with a plastic body look better than the metallic ones.

External protection

This is a really important factor to consider as well. There is no way you should ignore this as the external guard helps in prevention of birds and lizards from housing the assembly. Exhaust fans now come with automatic external guards and also ensures protection from dust.

Noise Level

Who wants to be cooking in the kitchen with a noisy exhaust playing in the background? No one right? And that’s why the sound level emitted by an exhaust fan should be looked into. Most exhaust fans do deliver a silent operation now. However, check for the sound pressure level before buying the exhaust.

Air Flow Capacity

The air flow capacity in the bathroom is measured as per the CFM (cubic feet per minute). To get the right exhaust fan remember one thing the exhaust fan should have 1 cfm per square foot in your bathroom. This is a crucial factor to assure adequate ventilation.

Speaking about the kitchen area, you have to apply the thumb rule which is – spaces less than 100 square feet need one CFM per square feet. Make your buying decision based on this.

Energy Efficiency

Energy savings depends completely on the energy efficiency of the exhaust fan. Want to save up that extra bucks on your electricity bill? Buy an exhaust fan which is energy efficient. An energy efficient exhaust can help you save 20-30% more than a standard exhaust fan. Bajaj Maxio 150mm Exhaust Fan is a highly efficient exhaust fan as it consumes 21 watts of power only.


We all know how important warranty is but do we really check the warranty period before buying the product? If not, it’s about time you do. Don’t get excited with the features and forget about the warranty period. Sooner or later “warranty” does come into action. It assures some kind of reliability and in purchase of every electric appliance it plays a big role. Buy an exhaust fan which assures a minimum of 2 years of warranty period.


Speaking about the budget, yes it is very important to each one of us. Depending upon your budget you can decide which fan you must buy. If you are looking to buy the best high speed ceiling fan, it will come with a cost but also have all top notch features. Remember one thumb rule- more efficiency leads to less power consumption. Therefore, you can benefit yourself with energy savings. So restricting on the budget would not be cost effective in the long run.

Additional Features

Exhaust fans do come with varied characteristics for better efficiency and convenience.

  • Exhaust fans do come with supplementary lightings to provide users with soft illumination at night.
  • Few exhaust fans are equipped with heaters. This is an added advantage if you live in a cold place.
  • Exhaust fans come along with motion and humidity sensors. A humidity sensor is a great feature. It will notify the exhaust to switch on once the humidity rises and switch off once the humidity reduces. The motion sensor notifies the fan to switch on if someone enters the bathroom.
  • Exhaust fans also come with speed control settings.

What size exhaust fan should you buy?

The exhaust fan should depend on the area you require it for. As we discussed above, you will require 1 CFM per square foot. So how do you identify the square foot of the area? Simply multiply the width with the length and the height of the area. Once you do that, look for the specifications.

Here is a simple calculation you can follow:

  • Calculate the size of the room by multiplying the length with the width with the height (LxWxH) For example: 10 x 15 x 10 =1500 cubic foot
  • For the bathroom you can multiply the size of the area with the air changing rate (ACH) and divide it with the number of minutes in an hour. So here it goes.. 1500 (1500 x 8 ) / 60 = 200 CFM. Therefore, the size of the ventilation fan would be 200 CFM.

Types of Exhaust Fans

There are two types of exhaust Fans- Axial and Centrifugal Fans.

Axial Exhaust Fans

These are commonly wall mounted. They draw air straight through the fan. Axial exhaust fans are capable of eliminating huge volumes of air.

Centrifugal Exhaust Fans

These are identified based on the type of blades- forward inclined, backward inclined and straight radial blades. They are capable of functioning at high resistance. Centrifugal exhaust fans are extremely efficient in eliminating huge amounts of dust. They do not get clogged or abraded by the contaminants.

How does an Exhaust Fan work?

Areas like Kitchen, Bathroom, Storeroom etc are prone to moisture and humidity. How to maintain a fresh air environment? There is just one solution to this- An exhaust fan.

Let’s see how they function.

An exhaust fan functions on a simple rule which is suction of humid air, bad odour and all other harmful substances. These elements are sucked out and put into the ducting system and then thrown out. This entire process makes it possible for fresh to enter from a vent, replacing the contaminated air completely. With the advanced technology, exhaust fans are equipped with a sensor as well. In case of any steam in the particular area, the sensors get activated.

A few exhaust fans are also equipped with capacitors. They control the electric energy flowing into the motor. Once you select a high speed, the speed of the blade increases rapidly, and the capacitor directs more electricity to the motor.

What are the Benefits of an Exhaust Fan?

An exhaust fan is the most undervalued appliance in the house. But trust me, it is so very important. You cannot or should I say should not do without it. Having an exhaust fan at home can benefit you in so many ways. Let’s talk about it.

  • The most known fact- strains out impure air. An exhaust will efficiently filter out moist, humidity, dust and impure air.
  • Cooking can surely cause burning smells. Sometimes the smell is so pungent it can get impossible to be there and cook further. Exhaust eradicates this burning smell in no time.

  • We can end this by saying an exhaust will give you all the comfort at home at a bare minimum cost.

How to clean an Exhaust Fan at Home?

Most people do not give cleaning the exhaust fan a thought. Why don’t you observe your exhaust fan. Is there dust or unnecessary particles on it? If yes, it is time you clean it right away.

  • Firstly, check your exhaust fan is covered with a mesh filter. Remove it and clean it with lukewarm and soapy water. You can also use a mixture of ammonia and hot water. In the end wipe it off with a damp cloth.
  • Again, clean the exhaust fan blades with soapy water. You can also make a mixture of warm water with baking soda and ammonia. A trisodium phosphate solution is also a good option. Make sure you wear rubber gloves and a mask while doing so. Wipe off the blades with a cloth or paper towels.
  • Break down the grease with the help of caustic chemicals. The safest way to do it is with the help of a chemical foamer. Make use of hot water to rinse away the surplus.
  • It is important to detach all the screw holdings of the exhaust fan. You can make use of an unsharpened knife to get into the smaller areas.
  • Make use of scrappers. A small steam cleaner can easily remove all the dirt and grease.
  • Make use of your toothbrush. Apply a paste of vinegar or a dish washing liquid and and brush it in between the sections.

Before you begin with this make sure to switch off the power. Once you are done put the exhaust fan back together.
