Top 7 Best Air Purifier for Home in India 2020

15 out of 20 most polluted cities are in India— as found by Who (World Health Organization). But surprisingly more than 2 million people die premature deaths because of indoor air pollution. Recent research shows that indoors can be 5 times deadlier than outdoor air! Yes you heard it right!

This is mainly because of poor ventilation, gas fumes from stoves, smoke, paint fumes, varnishes, fungal spores and electronic devices that we bring into home. Since we spend most of the at-home we have higher chances of exposure to all those hazardous allergens.

This is where Air purifiers can help matters a lot! It mainly consists of efficient particulate filters that are designed to eliminate almost 99.97% of airborne allergens.

A best air purifier should have these filters to filter out polluted air:

  • HEPA filter – This particular filter is proven to remove mainly dust, pollen, mold, smoke, pet dander, and even hair.
  • Carbon filter – This can mainly get rid of gas and chemical fumes, bad odor, and smoke, etc.
  • Ionic Filter – This can remove dust, pollen, volatile organic compounds, fungi, bacteria, viruses, and smoke.
  • UV Light – This filter can get rid of main micro-organisms like bacteria, viruses, and germs, etc.

Other than these filters, there are many other things to look for if you are in the lookout for a proper air purifier.

Size of the Room –

Rooms CADR
Bedrooms (300 Sq.ft) 140
Living rooms (400 Sq.ft) 250
Whole house 400

Here CADR refers to the clean-air delivery rate. This measures the cleaning speed and efficiency of the air purifier for removing airborne allergens. ACH is another important feature. This refers to air changes per hour. A good air purifier generally starts at 6 to 8 ACH rating.

Other notable factors to consider are noise, appropriate placement, maintenance costs and energy consumption. If you find all these a bit overwhelming, don’t worry, you can go through our “ Buying Guide ” to make your buying process smooth and hassle-free.

Things to Consider While Purchasing an Air Purifier

To choose an air purifier, you need to consider several factors like room size, power consumption, noise levels and finally the cost. We have tested on many and checked the performance by switching to low-high speed variations.

Given below are the factors responsible for the better performance of air purifier. Check them in detail.

1. Types of filters used in air purifiers

Different air purifiers types target different pollutants, so it is important to identify the pollutants that you want to eliminate from the room and enjoy the fresh air. For your convenience, we have provided different types of filters used in purifiers. Let’s have a glance at the Top 5 air filters for home that are very popular now. (2)

a. HEPA Filter (High Efficiency Particulate Air)

This type of filtration process is considered the highest level of purification process. The US HEPA standard was developed long ago by the Atomic Energy Commission. Their goal was to capture the radioactive dust particles. 

There is a variation of it, name the True HEPA Filter, they are known to remove more than 99.97% of all the microscopic particles, even if they are as small as 0.3 microns. So, these types of filters can allow only the very small particles to pass by thereby, allergens like pollen or pet dander or mold spores or even dust particles will be eliminated. 

You will find several filters in the market that carries the name HEPA but not all of them are equipped for such delicate work. You need to look for the certification or the label that says “True HEPA Filter”.

There are also other filters in the market that uses the terms like “HEPA-type” or “HEPA-like”, you should know that these filters are not true HEPA. These are inferior filters capable of blocking particles sized 2-5 microns. 

This is probably the main reason why one HEPA filter is more expensive than the other. So, when you are getting a HEPA filter you need to look for the HEPA label specifically. Sadly, all the HEPA filter are not created equally. Here the size matters, the more square footage in a HEPA filter the more number of particles it will be able to remove. The size, material and even the manufacture all varies and plays a key role into it performance. 

Pollutants removed – pollens, mold, dust, pet dander, hair, and even smoke. 


  • Top certified filters
  • Trap all type of particles of very small size and does not let them release into the air
  • It is suitable for different respiratory issues 


  • Requires regular maintenance and replacement for maximum effectiveness 
  • Most expensive filtration system 
  • Incapable of removing odours and chemical fumes 
  • It employs a fan in order to suck in the air at the highest rate which can be very noisy

b. Carbon filter

Another variation of air filters is called the Activated Carbon Filters. These sort of filters are not really used alone to purify the air, it is a very rare occurrence. Usually, they are accompanied by other filters. These activated carbon filters excels at eliminating or absorbing irritating odours. They are also capable of neutralizing smoke, chemicals, and fumes.

The activated carbon filters use a very specific form of carbon containing millions of very tiny pores, these pores are very absorbent. As it consists of so many pores, the surface area is exceptionally large which inherently traps all the fumes, gases and odours.

You may not know this but if you simply treat carbon with oxygen, millions of pores will be opened on it. These are very small microscopic pores which make the surface area of ​​the carbon very large. Thus a single pound of activated carbon has a surface area of ​​60 to 150 acres.

As it has such large surface area, it is best suited for absorbing gases and odours. That generous surface area is just perfect for bonding with molecules of chemical or vapor. When the carbon filter is larger, then the amount of chemicals absorbed by it will be higher and it will also be able to work for an extended period of time. After it is full, it will no longer be able to absorb chemicals and then you have to replace it. 

Unfortunately, this activated carbon filter can’t be used to trap particles which are causing you allergies or asthma or any irritation in general. But it can get rid of smells, effectively. Basically, if you use these filters your room will smell fresh and clean. And this is the main reason, why activated carbon filters aren’t used alone; they are accompanied by another filter.

Pollutants removed chemical and gas fumes, odours, smells originating from pets, cooking, smoke and smell of paint and the smell from cleaning products 


  • Helps to keep a room fresh 
  • Compared to other filters it is cheaper
  • Effective for people living in industrial areas


  • Only useful for removing gaseous fumes, smells and odours from the room, there are no other applications

c. Ionic filter

This is a completely different type of filtration system. This type of filter emits a charged cloud of in the air, the ions present inside the cloud get attached to the impurities present in the air and it forces them to cling to the nearby surface.

One of the main disadvantages of this sort of filters is the dirty spot. If you keep the ion generator close to a wall or on the floor, it will create spots covered with dirt.

A few ionic air purifiers are equipped with an electrostatic collection plate. This plate attracts the fallen particles in order to remove them from the room. As it does not eliminate the impurities, it forces them to get attached to a surface. But this process is also capable of eliminating ultra-fine particles sizes as small as 0.01 microns.

Pollutants Removed – dust, pollen, mold spores, volatile organic compounds, fungi, different bacteria’s and viruses, also visible smoke.


  • This filter is practically maintenance free; you don’t need to replace it. 
  • It is lot cheaper 
  • Noise free. 


  • Pollutants stays in the room cling to the surfaces. Unless you have an electrostatic plate or a collection plate you can’t remove them. 
  • Needs cleaning very frequently
  • It is not capable of eliminating odours 
  • Produce small amount of ozone as the by-product which is not really good for health

d. Ultra Violet or UV Light Filter

This is unlike any other filtration system we have mentioned before. There is actually a UV lamp inside the purifier. It emits an invisible light that contains UV light. This light attacks the pollutants as they are passing through the filter. 

The bulb is of 20 watt and it emits UV that kills pathogens, germs, and microbes. It is also certified by California Air Resource Board, making the process ozone free. 

The UV light is contained inside the air purifier; it is not released into the room. This an air purifier technology that uses the UV-C band of the Ultra Violet Spectrum. You may not know this but this particular band of UV is perfectly safe for us there aren’t any side effects.

This sort of setup, like air purifiers equipped with UV filters is generally used inside the hospitals, in order to keep the environment sterile. They can also be used in the kitchens, laboratories or even at the day-care centers. If you have the tendency to get sick very often then you need this air purifier equipped with a germicidal filter or UV lamp may. It will boost your immunity. 

The main work of the UV ray is to completely destroy the bacteria and viruses at the molecular level. What you are getting is a pretty good sterile environment with clean air. 

Pollutants removed – all sort of micro-organisms as bacteria, viruses, germs.


  • These filters are capable of lasting for thousands of hours and rarely requires replacement
  • Creates a sterile environment, cuts down the number of germs inside your room 

Disadvantages of Ultra Violet Light Filters

  • It is capable of only killing the viruses, bacteria and germs. So, this filter can’t be bought as a standalone device. 
  • Mostly comes as an attachment with a HEPA or an Ionic air purifier

e. Ozone filter

This is a completely different type of air purification system and it is not good for health. This type of purifier manufacturers Ozone gas intentionally. Although, there are article and statements which are made to make you believe that these devices are safe for public use but they are not, actually.

Several health professionals have spoken against such claims and they have stated that there are no such agencies authorized by the federal government to manufacture such devices. If you get exposed to ozone, it may aggravate your asthma symptoms and if you consume it in high levels then it is sufficient enough to create scars your lungs.

Sadly, there are still different brands Ozone air purifiers available in the market and the amount of Ozone produced by them obviously varies but you also have to know that there are several chemicals we use every day that reacts to ozone. Several studies have shown that the ozone air purifiers help in the growth of a few specific biological agents. It is also impossible for it to clean the in such low concentrations.   

Stay away from Ozone Purifiers

This air purification is extremely dangerous. It can cause lung tissue damage, not safe to use in the closed confinements of a room. These purifiers are also restricted in the State of California. So, just remember these points, next time you go to purchase an air purifier.

2. Choosing the right Size Air Purifier

Another important thong to consider is the size of the purifier which is most of the times neglected by the consumers. But you need to know which purifier is the best for your home and for your health.

First, you need to check the square footage rating on the packaging, and then you need to compare it to the size room where it will be placed. 

If the square footage rating of the purifier is equal or greater than the size of the room then it was definitely an excellent choice by you. 

But, here’s the proper way to measure it;

You will need the measurement like the width and length of the room in feet and if you multiply them, you will achieve the total square footage.

So, the calculation is; 10 ′ x 20 ′ room = 200 sq. ft.

If you have multiple connected rooms, such as a living and dining room and a kitchen, then you have to make additional calculations. You just have to add up the total area in square foot.

So, the calculation is; 10 ′ x 20 ′ living room = 200 sq. ft., 10 ′ x 10 ′ dining room = 100 sq. ft., and finally, 15 ′ x 20 ′ kitchen = 300 sq. ft. The together you will get (200 + 100 + 300) equals 600 sq. ft.

So, after completing the calculation you need to know the minimum sq. ft rating of the purifier in order to learn its efficiency. 

3. ACH and CADR ratings

Well, you are trying to purchase an air purifier so you will most definitely come across two of the very common and specific ratings;

  • ACH
  • CADR

Air Changes Per Hour or ACH

The ACH rating is most of the times it is ignored by the customers as they are unable to understand it. Unfortunately, this particular rating tells the customers the efficiency of the air purifiers. 

The ACH rating stand for the rate of exchanged air in the room by the purifier every hour. The rating includes 4X, 5X or 6X denominations. 5X means that the polluted air in that particular space gets trapped and then recycled within 5 hour interval. The higher the number, greater the efficiency of the purifier! 

You also need to know that this rating is directly linked to the max sq. ft the purifier can handle. So, if the purifier has a 5X rating and specified that it can cover 300 sq. ft. specified efficiency. 

CADR abbreviated as Clean Air Delivery Rate. It is actually a performance indicator to determine the efficiency of an air purifier. Most people often get confused with the terminologies like airflow rate, filters, and CADR air purifiers. Here is what exactly the CADR rate is all about.

What is CADR?

CADR rate defines the maximum amount of clean air offered by an air purifier. In other words, it can be expressed as how well the purifier can reduce the allergens, pollutants, and chemicals in a room. Higher the contaminants, faster it purifies the air.

The tests of CADR are being carried out by AHAM-Association of Home Appliances Manufacturers to analyze the performance of a purifier with respect to dust, pollen, and tobacco. Initially, the purifier is kept in a small / medium sized room and CADR rate, the percentage of impurities are determined in just a time gap of 10-20 minutes.

 Given below table completely explains the CADR ratings of different impurities present in a room.

Impurities CADR Rating (Microns)
Pollen 5 – 11
Dust 0.5 – 3
Tobacco smoke 0.10 – 1

To be more specific, higher CADR air purifier filters very quickly than the lower ones. In case, if both the purifiers have the same CADR-rating then purifying performance will be the same.

4. Portable, Whole house or Commercial Use?

There are several varieties of air purifiers found in the market. Some of them clean air by removing dust particles, molds and other allergens. So, we have compiles a list of our own different types of air purifiers. 

  • Portable air purifiers

These are also called room air purifiers. It does not need any heating or a cooling system. Best suited for bedrooms and they are also very cheap but their efficiency is amazing.

  • Whole-house air purifiers

You can also go with the whole-house purifiers. These purifiers are usually gets attached to a heating or a cooling system. They are capable of clearing big rooms and clearing allergy-related issues.

  • Commercial air purifiers

These purifiers are capable of removing a large number of contaminants from the air compared to standard air purifiers. So, if you are using a commercial purifier you must have to use it in a big room or for a long hallway. 

Such systems come with PCO and HEPA filter for protection against any type of harmful bacteria, chemicals and viruses.

5. Air Purifier Features You Need to Look

Here, we are going to tell you what you should look for while purchasing an air purifier. If you compare two or more machines together you will find that there is a wide variety if you include the additional features and customized upgrades. 

So, some of these features will cause some extra buck and learning all these things will definitely help you to purchase the best product suitable for your needs. 

Here are the features you need to look for in an air purifier;

  • Pre-filter 

These types of filters are capable of trapping the largest particles in the air. So, if this one is attached as an additional filter to your purifier, it will increase the lifecycle of the inner filter significantly. The Pre-filters are also very cheap and they are washable.

  • Digital Controls

The digital control will allow you to control and manipulate the settings of the purifier more precisely. 

  • Adjustable Fan Speeds 

Most purifiers come with a fan speed settings of 2 to5. The highest and the lowest range exist somewhere between them. Some purifiers are also equipped with turbo speed to accelerate the cleaning process.

  • Filter Replacement Indicators

Some filters are equipped with indicator that informs you when it is the right time to replace the filters. It simply means the filters are filled with pollutants; you need to change or wash them in order to make them work perfectly.

  • Programmable Timer 

The automatic turn off feature is available with almost every purifiers, these days. It simply helps to same electricity.

  • Carrying Handle

The carrying handles make the transportation of the purifier very efficient. It is a very heavy device so the addition of a handle is preferable.

  • Casters 

Works more like the handles, the casters are a set of wheels mounted below the purifier making it easier to move.

  • Antimicrobial Treatment 

This is a type of coating found on purifiers. It helps in preventing the spread of bacteria and microorganisms on internal filters, resulting in an increase in the lifespan of the filter.

  • Air Quality Sensors 

This sort of sensors are capable of monitoring the air, they look for specific pollutants and then adjusts the in order to remove those particles immediately.

  • PlasmaWave Technology 

An alternate method of ionizing the air! So, that it does not emit negative ions or worse produce ozone. This technology uses water vapor to achieve the same results. 

  • Photocatalytic Oxidation (PCO)

A very advanced filtering process equips the filters with UV Light in order to completely destroy the chemicals or other volatile organic compounds; even bacteria, mold and fungi.

  • Nightlight 

This light helps to locate the purifier inside a dark room.

  • Remote Control 

If you have this, then you will be able to operate the purifier from a significant distance. 

  • Mobile App 

This is the age of the app. They are almost everywhere, capable of doing anything. So, the addition of app will provide you with full access of the purifier via your cell phone. 

6. Other Considerable Points

This is the final stage of making the decision, which air purifier to get for your home. But there are some additional points to consider before you get to do that. 

  • Cost of the Air Purifier

The cost is the main factor to be considered before buying an air purifier. It gives a clear idea of what and how effectively you are going to use the purifier.

If you are on a very tight budget, and still wish to have the best home air purifier in India, then go with the basic models like Mi Air purifier 2S bundle with Echo Dot that comes at very low prices. Though it may not offer all the smart features, its main function is to remove the harmful chemicals in the air that causes great damage to human health.

The above-mentioned basic model may not solve all the purifying issues. So there is an urge of air purifiers that come with advanced features like smart navigation, and timer settings. Here in this article, we have mentioned some of the top-class purifiers like Coway,Honeywell,and Philips models that best match the consumer requirements.

  • Cost of Maintenance

If you simply maintain the purifier properly then they will work most efficiently. So, before getting the purifier to make sure you know how much it will cost to keep it running smoothly. 

The purifiers that are equipped with HEPA or Carbon filters need replacing frequently. These filters trap the particles so eventually they get clogged up when they can’t clean the air anymore.  

The HEPA or Carbon last about a year before they need replacing. So, find out the replacement cost. If you get the ionic air purifier you don’t have to worry about the maintenance. These machines are equipped with a type of electrostatic collection filter to collect pollutant particles from the air, but these filters are washable and reusable.

  • The Noise Level

If you get an air purifier equipped with a HEPA or a Carbon filter then you will see that those purifiers come with a fan. This fan sucks the air into the filter and then forces the clean air back into the room. Sometimes, it may feel like that these fans are making too much noise. 

But if you reduce the fan speed then the noise level will also be reduced. 

Generally, purifiers have only two speeds; high and low but there are few that are equipped with close to 5 types of speed like low, medium, high, turbo and automatic.

So, the noise level is a very important factor. If you are going to be using it in the bedroom, a high level of noise will make the air clean but it will not let you sleep well. 

So, go for a purifier that is properly sized for your preferred room. If it is too small then it will work too hard and the noise will be higher. As it will be operating at its highest setting!

But the ionic purifiers do not use filters and it also means that they don’t use fans. So, these types of filters are the best choice if you are looking for a low noise purifier.  

  • Consumption of Energy

Similar to other appliances in your home air purifiers will be plugged to your wall and will be running on electricity. As they require to run 24/7 for maximum efficiency, you need to consider the amount of energy it will require. Generally, the purifiers use 50-200 watts of power. But we would recommend getting a device with the Energy Star rating. It ensures that power consumption will be low. 

  • Manufacturer 

There are several manufacturers all over the world know for designing air purifiers for homes. Sadly, not all of them provide high-quality machinery. So, if you are getting a purifier, it is important to know the manufacturer. Just select a manufacturer with good background and reputation.

  • Warranty
