Last updated on April 16th, 2023

Maybe someone just told you to buy the best air purifier in India for home but you’re still in dilemma about whether it is useful or not. I can read your mind because I have seen my readers in utter confusion regarding the purchase of air purifiers.

If you’re also one of them, you’re at the right place! Because we have not just given you an air purifier buying guide, and not only honest reviews, you’re also going to clear your confusion about whether you need an air purifier or not in 2023!

So before discussing anything about the “best air purifiers in India 2023”, first let’s know what an air purifier is!

What is an Air Purifier?

An air purifier/air cleaner is a device (a health care device) that is designed to improve air quality. It cleans the air by removing contaminants from the air.

People with allergic symptoms and asthmatic sufferers must have an air purifier at home. As these devices are very beneficial for health.

Also, the people living in industrial areas or polluted cities like Delhi, Mumbai Kanpur, Faridabad, Patna, Gaya, Varanasi, Lucknow, Agra, Gurgaon, Muzaffarpur, Jaipur, Patiala, Jodhpur, Ahmedabad must buy an air cleaner/air purifier.

Do I Need an Air Purifier if I Don’t Live in Delhi NCR or Any Popular Polluted City?

The simple answer is to check it yourself! Usually, the AQI (Air Quality Index) level under 30 is considered to be good but in India, under 50 is okay. You can check your city’s AQI and if it’s not under 50, you need an air purifier.

Apart from outdoor pollution, you need an air purifier because of indoor pollution too. Because there are impurities in the air of your home responsible for indoor air pollution. Therefore to inhale healthy and fresh air that is free from harmful pollutants (both visible & invisible) you need the best air purifier in India for home.

The principal source of indoor pollution in India is the combustion products of biomass fuels that include health-hazarding suspended particulate matter, carbon monoxide, polyaromatic hydrocarbons, poly organic matter, and formaldehyde.

Look at these figures below:

• Indoor air pollution is due to 4 major factors: combustion, building materials, bioaerosols and the ground under the building. Besides these factors, there are major contaminants that not only spoil the indoor environment but also the person’s health as given below.
• In India, out of the total population using fuel for cooking; 49% use firewood; 8.9% cow dung cake; 1.5% coal, lignite, or charcoal; 2.9% kerosene; 28.6% liquefied petroleum gas (LPG); 0.1% electricity; 0.4% biogas; and 0.5% any other means.
• Indoor air pollution has a potential effect on health resulting in about 2 million premature deaths per year, wherein 44% are due to pneumonia, 54% from chronic obstructive pulmonary disease (COPD), and 2% from lung cancer.
• The most affected groups are women and younger children, as they spend maximum time at home.

How to Know Whether I Urgently Need the Best Air Purifier in India for My Home or Not?

It would be a wise decision to invest in a good air purifier if you have the following conditions;

• In case you are allergic to the dust
• having asthma or COPD
• suffering from other allergy symptoms like itchy eyes, or headaches
• bad smell
• living in a metro city in India
• residing in an industrial area
• construction is going on nearby
• living in a place where dust mites are everywhere

How Did We Select These 10 Best Air Purifiers for You?

You have learned by now what an air purifier is and whether you need it or not. But there are other questions too:

• How would you rate them?
• Are all of them capable of fighting pollutants harmlessly?
• Why do I need to read this guide if there are best-sellers available?

Because you can’t select a good air purifier just by looking at the best-selling list on Amazon or other sites. The reason is all air purifiers are not created equal. And many times it’s a marketing tactic for brands.

So, it’s not a good idea to buy any random air purifier from the market and expect it to give the desired results. You must have certain knowledge about some important factors and features like filter type, certification, noise level, ozone free technologies.

In this article, I have listed the best air purifiers in India for home use that are available to buy online in 2023.

Buying Guide _{(for buying the best air purifier in India for Home)}

There are many things you need to take care of while purchasing an air purifier both online & offline. In this section, you will learn how to choose the best air purifier in India for your home.

However, a few factors need to be explained in more detail so I will lay more emphasis on them in the next sections.

For example, ‘types of pollutants’ has been explained separately later in this article.

You just keep reading for now.

1. Types of pollutants/ impurities you wish to get rid of

There are various types and sizes of impurities you encounter indoors.

First, have a look at:

1.1. Types of impurities/pollutants found in the air of your home

• Dust
• Bacteria & viruses
• Pollens
• Plant spores and fungi
• Allergens
• Pet dander and hair
• Mould spores
• Tobacco and wood smoke, and their smell
• Household odours from cooking, pets and chemical cleaners
• Toxic gases from pesticides, and aerosol sprays.
• Volatile Organic Compounds (VOCs) are found in paint, varnishes, cleaning supplies, new carpets and building materials

These particles of impurities exist in various sizes that are categorized in a range lying between 0.04 microns to 100 microns.

This is the reason an air purifier is equipped with 2 or 3 filters usually. Different filters are used for different purposes which we discuss later in the article.

You need to know just one thing, an air purifier with a HEPA filter is the best air purifier for your home to get rid of such airborne impurities.

1.2. Coming to the sizes of impurities

There are generally two measurements:

• PM10 and
• PM2.5

through which the diameters of impurities are calculated and their sizes are defined.

If a pollutant is as small as 2.5 micrometres or less than it, that particular particle is said to be the PM2.5 type of pollutant or less.

The same goes for PM10. Here the diameter of the pollutant is of size 10 diameter or less. Just like PM2.5, PM10 is also hazardous to our health but they are comparatively bigger-sized particles.

And, PM refers to particulate matter.

As I told you above, the diameter is calculated in micrometres. And a micron is around 1/25000 of an inch.

I show you the graphic from the EPA (US Environmental Protection Agency) for a rough guess.

As you can see in the pic given by the US Environmental Protection Agency, the size of PM2.5 objects is so small that human hair looks like a trunk of a big fat tree!

In a rough estimate, PM2.5 equals around 3% of the thickness of human hair. These objects are not visible to the naked eye. But they are present everywhere around us, in our house, room, and the whole atmosphere. And sadly, we are inhaling them regularly.

They enter your body through inhaling and can cause serious harm to your lungs and your entire system.

Meaning to say, we have such invisible enemies around us that can cause serious damage to our health at any time!

2. Types of filters in an air purifier

There are mainly 5 types of filters installed in modern air purifiers. But you need to know, that not all of them are safe to use.

Some air purifiers use filters that emit Ozone & other harmful gases that are hazardous to health.

But as I told you in the above section, an air purifier with the HEPA filter is the best air purifier you should buy for your home & office. A true HEPA filter mainly removes harmful pollutants of all sizes like PM 2.5, PM 10 or even as small as 0.3 microns.

Now there are also other sorts of impurities and invisible pollutants like the smell, formaldehyde, bacteria, viruses and other chemical compounds that need different filters to get removed.

That’s why air purifier brands use other filters like carbon filters, and ionizers to perfectly clean your air. There is also a pre-filter attached to air purifiers to provide first resistance to pollutants, i.e to trap larger particles.

To buy the best air purifier in India for home and to know more, head over to the section ‘type of filters’ covered at the end of this article.

3. CADR and ACH ratings

3.1. CADR (Clean Air Delivery Rate)

CADR is a scale measuring the performance of an air purifier. It’s a measure that tells how well a purifier is working. The quality of an air purifier is measured in terms of how quickly it cleans the air of the room or a particular space.

CADR is the rate that defines how quickly and efficiently an air purifier is cleaning the room. In simple language, it’s the maximum amount of clean air offered by an air purifier in a certain period.

In other words, it can be denoted as how effectively the purifier can eliminate the allergens, pollutants, chemicals, and microorganisms in a room.

Its unit is cubic meters per hour. If a particular air purifier has a CADR of 300 m3/h, it denotes the purifier can purifier 300 cubic meters of air in one hour. It can also be measured in minutes, I.e. cubic meters/minute.

There are also different CADR nos. for different pollutants in different air purifiers. And remember, the higher the CADR, the better the performance of the air purifier!

In case, both the purifiers have the same CADR rating, which simply means the purifying performance of both air purifiers will be the same.

Therefore CADR is the second most important factor to determine when buying the best air purifier in India.

3.2. ACH (Air Changes Per Hour)

The ACH rating stands for the rate at which an air purifier can exchange polluted air in an hour. It defines how frequently the air purifier recycles its round of cleaning pollutants and impurities in an hour.

And this rating is directly linked to the room area an air purifier can handle!

For example, if you have a 25’ X 25’ room and an air purifier with an ACH rating of 5, it entails that the air purifier is capable of exchanging the entire air in the room 7 times in an hour.

4. Purpose of air purifier? Home, commercial usage?

Not all air purifiers are created equal. Some are designed only for commercial purposes while others are dedicated to cleaning only home air.

Even for home use, there are many air purifiers available in the market from different brands and at different prices. The difference lies in the space where you’re going to install the air purifier at home.

For example, if you need an air purifier to clean the air of small to medium spaces like a bedroom, kitchen, or medium-sized living room, you need an air purifier featuring a medium coverage area of 300-500 sq. ft. and medium CADR of 200-300 m3/h around.

On the other hand, if you have a larger space or you want to cover multiple rooms, you would need a comparatively high CADR above 300 m3/h and a high coverage area above 500 sq. ft.

5. Features to look for while buying the best air purifier in India for home

Here are the 10 most important factors that you should know before buying so you can buy the best air purifier in India for your home.

5.1. Coverage area

As we discussed above, the coverage area depends upon your space. It’s usually measured in square feet. This is one of the most important factors on which air purifiers are rated.

Measure your room size, and target buying an air purifier having a coverage area higher than your room size.

For example, if your room size is 350 sq feet, go for an air purifier that can cover up to the coverage area of 450 sq. feet.

Therefore, measure your room size first, and then start your search to choose the best air purifier in India for your home.

5.2. Replacement filter period

This is one other important factor when choosing the best air purifier in India for home. If you have to change the filter very frequently, it costs you expensive.

An ideal filter should last long around 3-5 months. Else, the running cost of your air purifier would be high. But now, when people are using air purifiers 24 X 7 in metro cities, the period may vary as per the usage.

Also, check if the pre-filter is washable or not. Some air purifiers like Dyson Pure Hot+Cool send notification alerts to change the filters so you enjoy only fresh air.

5.3. Power consumption

For your device to be cost-effective, you should know if it consumes less power. It should be energy-efficient.

Usually, air purifiers consume power from 20 watts to 60 watts per hour. The less is better!

5.4. Noise level

You should look for the best quiet air purifier. Noise level is measured in dB. The higher its rating is, the louder the air purifier would be!

So, aim for getting an air purifier between the range of 20-60 dB!

The quietest air purifier can have a dB rating of 15-40 dB at low fan speed. Moderate levels can be rated at 40-60 dB. Any level above 55 or 60 dB is loud and can damage your hearing.

Some air purifiers come equipped with ‘night mode‘, switching on which, fan speed becomes low and you can enjoy a noise-free night.

5.5. Air purification technologies

Different companies use different air purification technologies to trap different types of pollutants.

You just need to remember one thing the technologies used should be complete ‘ozone free’.

Because many brands use the air cleaning method that emits ozone & other harmful gases.

5.6. Certification

The certification ensures the quality & standard of an air purifier. There are two standards in the industry to be taken seriously:

• AHAM (American)
• China

Most air purifiers made in India don’t have these two standards.

5.7. Your budget and cost of an air purifier

The best air purifier in India to buy is one that doesn’t hurt your pocket much. Meaning to say it is rich in features along with being affordable.

Therefore, determine your budget. Usually, good air purifiers in India are available from Rs. 10,000 to Rs. 55,000 depending upon the coverage area, filters used, and CADR.

The higher your space is, the more expensive your air purifier would be!

5.8. Cost of maintenance

You need to ensure, how many times the filter needs to be changed, whether you can change it for yourself or you need an engineer for it.

Also, the power consumption cost and its design(anti-fall design makes the device more durable) affect the cost of the air purifier.

5.9. Other features

Other features you should look for in an air purifier include:

• Sensors & control type- to monitor the performance
• Display and indicators- to monitor air quality & update info
• Mobile app- better user experience
• Modes- for example, night mode helps to reduce airflow speed for peaceful nights, auto humidity mode, auto purity mode
• Child lock system- if your child comes close to the device, it automatically locked
• Anti-fall design- doesn’t get damaged if it falls
• Adjustable fan speed, carrying handle, casters, programmable timer

If an air purifier has most of the above features, it is undoubtedly the best air purifier in India you should buy for your home.

5.10. Warranty and support

Different brands offer different types of warranties. Some provide on the filter, some on the device, and some on both.

Look for longer life and warranty of filters.

FAQ- Best Air Purifier in India for Home

2. What are the tips to use/handling air purifiers?

Here are some tips to get the most out of your air purifier:

• Place it in the right location in the right direction especially if your room is large.
• Change the filters regularly. Though, some air purifiers have a built-in notification to alert you about the changing date of the filter. While some others don’t. So, take care of it. Else you will be breathing in dirty air.
• Operate it when you are indoors. Don’t keep it on when you leave the house. Else the filters would get out of order soon. However, if you live in a metro city, it’s recommended to run it for 24 hours.
• Close the doors and windows while using them.

3. Air purifier brands: which is the best brand in India?

There are many brands available in India. But, Philips, Dyson, and Havells are leading in the air purifier industry this time.

Dyson brand manufactures air purifiers with some advanced and cool features. While Havells is an Indian brand (I recommend and support this) known for making the best HEPA air purifiers with advanced true HEPA filtration technologies at affordable prices.

Philips is also affordable and popular for using ozone-free technologies.

4. What is an air purifier good for? Do air purifiers work in India?

We have discussed above the usage of air purifiers. And, yes, air purifiers work in India.

India is the 2nd most polluted country in the world. And due to social structure, there are usually large and big families.

However, the nuclear family is becoming very common in India but is still limited to the metro and big cities only. There are still joint families in small cities and towns.

When a large no of people share a house, there is more cooking and other factors of indoor pollution arise.

5. Where should I place my air purifier?

You should place it at least 5-10 feet away from your bed. And the directions should be towards you.

Please remember not to place it too far from where you spend most of your time.

Place it where you need to clean the air most. If not comfortable, you can easily change the place as they are portable.

6. Is buying the best air purifier in India for home a waste of money?

You are not unknown of the fact that how indoor pollution during modern times can harm your health. So, air purifiers are not a waste of money.

Many people don’t realize its need because they are unable to see the invisible pollutants around them.

An air purifier can work best for a person who is having breathing problems, asthma, and allergy symptoms.

7. How do I know I need to change the filters?

Some air purifiers like Dyson come with a built-in notification that reminds you of replacing the filters.

The other ones without this feature show the expiry period of filters so you manually check and replace the filters.

9. How do I know if my air purifier is working?

You can check it by seeing the indicators and displaying them. If it’s working, it will show the nos. and notifications.

Another way is checking the airflow which happens due to its fan. When an air purifier works, it pulls air from the room to remove dust and other pollutants.

10. Do I need an air purifier for each room?

No, you don’t. Buy the air purifier for the place in your home where you need to clean the air or where you spend most of your time.

If you have a big house or a big family or more than one family, you should go for another purifier.

11. How often should I run my HEPA air purifier?

You can run it 24 x 7 for better performance. However, it may damage the filters soon. But it’s recommended if you or your spouse are living indoors 24 x 7.

12. Can an air purifier make you sick?

Yes, air purifiers using filters that emit ozone or other harmful gases can make you very sick.

So ensure all the air purification technologies and filters the brand is using.

Else it can worsen your health.

13. Do air purifiers make the air dry?

No. They don’t.

14. How and when to clean an air purifier?

Yes, it’s a good idea. You can clean the outside, and inside, and clean their filters. Use a soft brush.

15. Can be buying the best air purifier in India for home to remove COVID-19?

The straight answer is No. The reason is coronavirus doesn’t transmit through the air, rather it’s a droplet-spread virus. While an air purifier can remove and trap the particles and viruses which are airborne.

But. experts are still recommending you should use a HEPA air purifier as a tool to protect yourself & your family at home during corona time.

Because a good quality HEPA air purifier at home can help you maintain your indoor air quality. It is a piece of technology equipment that will clean home air by removing dust and other viruses and safeguard your health.

Types of Pollutants/ Impurities in the Air in Detail

_{(answer to the question “Do you really need the best air purifier in India for home?”)}

According to the reports, scientific studies, and the figures given by the WHO, pollutants released indoors are 10 % more likely to harm our health than those released outdoors.

It happens because the air inside your house enables potential airborne particles and pollutants.

An Airborne particle is a particulate matter (PM) that contains dust, pet dander, pollen, spores, allergens, fungi, bacteria, and viruses.

All of these PM objects (both visible & invisible) are accountable for creating severe health conditions such as allergies, asthma, and other breathing problems.

Some people who are allergic to these pollutants notice the symptoms immediately after coming to their proximity, while some other people notice the effects after remaining exposed to them for a longer time.

Therefore,  you first need to be aware of the type of impurities that are currently polluting your air, before purchasing an air purifier.

As we discussed above, there are different types of visible (large particles like dust) and non-visible pollutants (PM 2.5 LEVEL) that prevent you from taking fresh air.

And depending upon their types, different purifiers are designed using different air purification technologies.

So,  the first thing you should care about while buying an air purifier is to identify the type of pollutants.

1. Allergens

are airborne particles that are present in every household. They include pet dander, dust mite, plant spores, mould, fungi, and pollen.

Allergens are the most common source of allergies and asthma.

2. Smokes

Smokes of tobacco and weed are the traditional source of indoor pollution. These indoor pollutants arise when someone creates smoke.

It degrades air quality, makes us sick, and even causes cancer.

Smoke can be very irritating to kids and women in the house and all other people who don’t smoke.

3. Odours

Odours inside the house include toxins, the smell of cooking gases and other harmful gases, and pollutants like pesticides, chemical cleaners, and aerosols.

Strong odours may cause a burning sensation and irritation to the eye, nose, throat or lungs.

Some people feel the immediate effect. They feel sneezing, coughing or other breathing issues.

Odours are very common to be found in a house, so it’s not easy to remove them.

An activated carbon filter is used in air purifiers to absorb such gases & odours and reduce their quality from the atmosphere.

4. The VOCs

VOCs stands for Volatile Organic Compounds. They are chemicals that have a high vapour pressure even at normal room temperature.

The VOCs can harm your health by irritating your eyes, nose, or your skin. The short-term effects are common headaches, nausea, and throat infections.

While the long-term effects include severe chronic health conditions. It can worsen your asthma and the worst effect it can give is damaging the nervous system.

The names of these organic chemical compounds are formaldehyde, benzene, ethylene, and a few others.

In households, they are present in paints, varnishes, new carpets, glues, adhesive products, cleaners, and building supplies.

5. The micro-organisms

The pollutants in this category are hazardous to our health. They can harm you even if you are not allergic to them.

The most common damage they can bring is disrupting your respiratory system.

If a person is regularly in contact with them, he/she is going to get affected either immediately or in the longer run.

The names of this category of impurities include antigens, pathogens, protozoa, mold, fungi, bacteria, and viruses.

These contaminants are the most common germs that are also found in microscopic plant bodies causing a health risk.

What makes them more dangerous is their invisibility. You are not able to see them as dust particles. But they are present in the atmosphere to create disturbances and irritations.

If you want to get rid of viruses, you should buy an air purifier with a HEPA filter that can remove the viruses.

Types of filters in Detail _{(before buying the best air purifier in India for home)}

As you know there are different types of impurities. When pollutants exist of different kinds, there would be different technologies to eliminate them.

For that matter, different filters are designed for different purposes. There are mainly 5 types of filters in trend which are used in air purifiers to target different pollutants.

Therefore, it’s important to know the functions of these filters.

1. Pre-filters

Pre-filters usually come attached to other filters in an air purifier. They are designed to trap larger particles of dust, hair, and other pollutants.

The pre-filters are usually washable and don’t need an engineer to get them changed.

2. HEPA Filter (High-Efficiency Particulate absorbing Air)

HEPA stands for high-efficiency particulate air. During your research on buying an air purifier, you will find that most air purifiers are using HEPA filters.

Yes, because, the HEPA filtration process is the highest level of the purification process. That’s why HEPA filters are the most expensive in the market.

The US HEPA standard was originally invented by the Atomic Energy Commission to capture radioactive dust particles.

A True HEPA Filter used in modern air purifiers can remove more than 99.97% of all microscopic particles. It targets harmful pollutants of all sizes like PM 2.5, PM 10 or even as small as 0.3 microns.

Pollutants removed

A true HEPA filter is capable of trapping both visible and invisible particles.

• allergens like pollens, pet dander
• hair
• mold spores,
• dust particles,
• tobacco smoke.

Positives

• HEPA filters are top-certified filters
• Capture pollutants of very small size
• Perfect for different respiratory issues

Negatives

• Most Expensive filter
• Noisy
• regular maintenance is needed.
• Incapable of eliminating odours and fumes.

Generally, an air purifier uses a combo of HEPA and activated carbon filters or a combination of 2 or 3 filters to remove all kinds of pollutants from the air and provide the best purification system.

Not every Hepa is worth buying for

It’s a very important thing to notice that not every filter labelled as ‘HEPA’ is a HEPA filter. While buying an air purifier for home, you should check which filter that air purifier is using.

Is it the original HEPA or just a copy of HEPA?

Because there are several filters in the market carrying the name HEPA but they don’t provide quality work.

You need to look for the label or certification saying ‘True HEPA Filter’.

Beware of the terms that are currently being used in the market:

like “HEPA-type” or “HEPA-like”, you should be aware that the air purifiers using such filters can’t provide quality.

3. Carbon filter

An activated carbon filter can’t trap particles, hence it doesn’t protect you from allergies, asthma or any other irritations caused by PM2.5 or PM10 pollutants.

But activated carbon filters use a very specific technology that can neutralise smoke and absorb all the bad odours, smells, and fumes effectively.

This is the reason they are not used alone to purify the air. Usually, they are accompanied by other filters like HEPA.

Pollutants removed – (change chronology)

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

Positives

• keeps a room free from odours
• cheaper
• A must-have appliance for people residing in industrial areas

Negatives

Can’t remove particles, only useful for absorbing smells and gases

4. Ionic filter

This is a completely different type of filtration technology, unlike HEPA or carbon filters.

Rather it works on the technology where the filter emits the breeze (filled ions) in the air, the ions get attached to the pollutants and force the impurities to cling to the nearby surface.

That’s why the wall where you put the air purifier gets dirty.

But the big advantage is this technology can eliminate ultra-fine particles sized as small as 0.01 microns.

Pollutants Removed – (change chronology)

• dust,
• pollen,
• mould spores,
• volatile organic compounds,
• fungi,
• different bacteria and viruses,
• also visible smoke.

Positives

• maintenance-free
• cheap
• noise-free.

Negatives

• Dirty surface (you need a collection plate to remove impurities)
• Maintenance
• not capable of eliminating odours
• Produce a small amount of ozone as the by-product which is not good for the health

5. Ultra Violet or UV Light Filter

UV light filter is generally used in hospitals to make the environment sterile. They can also be used in kitchens.

The air purifiers equipped with UV filters are also good for people who often get sick.

Pollutants removed

Completely removes all sorts of micro-organisms such as bacteria, viruses, and germs.

Positives

• Long-lasting & no hassle replacements
• cut down the number of germs inside your room

Negatives

• Kills only viruses, bacteria and germs.
• Like a carbon filter, it mostly comes as an attachment with a HEPA air purifier

6. Ozone filter

The ozone filters purify the air but emit Ozone which is not good for health. Sadly, some brands manufacture ozone purification interactions.

So you need to stay away from them. They aren’t safe to use and may aggravate your asthma condition.

And if you consume regularly,  it is sufficient to damage your lungs.
