Top 9 Best Air Purifiers in India 2022

Best Air Purifiers in India


Many people think that the air-purifier is a present day creation just because of its advanced features and sleek look, but it’s not the case. They have been around for many years. You can trace down its origin back from the industrial revolution. This was the decisive time in the history when a group of people notice the consequences of air pollution on human beings.

The Growth of Air Purification Technology:

Coal was the only power source to sprint machines and supply heat, at the time of industrial revolution. Although, this crude oil releases harmful smog, and foul smelling air. After this, inventors started to work on the devices that can filter the air. For example, in 1823 John and Charles Dean came up with the idea of primitive air purification system, which allowed firefighters to inhale clean air in smoky buildings. It advanced much further when John Tyndall created a personal respirator in 1840.

HEPA, high-efficiency particulate air-filter was originated in World War II, to help out lab workers and soldiers associated with the creation of atomic bomb. As this device get hold of microscopic particles out of the air and eliminate other irritants. Later many other air purification systems got motivated by this concept resulting in improved residential air quality.

Types of Air Purifiers:

These HEPA filters are originated focusing on the proportions of the particles to be extracted. Finer particles can be removed from the air if the pores in the HEPA material are finer. Although the filter material will be blocked sooner or later in the process of collecting finer particles, and needs to be restore routinely. It specifies the substance of the filter fabric that affix the filter pore size. These filters carry binders offering more durability but also allow filter to clog soon.

Air-purifying systems armed with HEPA filters catch the particles and don’t throw away.  These systems engage other processes also to complete its job. Like a fan forced air system to make sure that the air is passing through the filter, and a high voltage light for reducing viruses and germs. To grasp tiny volatile chemical molecules an activated carbon is frequently used, changing them from gaseous one to harder state.


Most of the air-purifiers disinfect the air by fleeting through the filter and clean particles. And they are called air cleaners in domestic level, these filters are generally a segment of cooling or heating system. There is a gap between the air return duct and furnace thus filter housing is installed.

The air that fleets into the furnace is filtered as the filter cartridge skids into the housing. Besides pulling out contaminants from the air, it rules out the harm to the furnace caused by dust and dirt. It can be positioned in the air requite outlet in your home.

Very thick filters have tiny gaps enabling it to clutch small particles. Air filters are quite expensive and you have to keep changing them for its proper functioning. Some of them are washable. They can control air flow via system resulting in dropped affectivity.

Ozone Generators:

This one is built to modify molecules of oxygen and convert them into ozone, a molecule consists of three oxygen atoms. Oxygen in the atmosphere has dixygen, a molecule consisting two oxygen atoms.  Makers of this device allege that ozone sanitize and purifies the air. And many boast about other advantages from the presence of ozone.


Most purifiers combine an adsorbent material to get rid of smell, gas and chemicals in the air. Adsorption is an activity of one substance being confined on top of another substance.

Mostly an ordinary adsorbent is charcoal, which is immensely penetrable and has lot of microscopic issues to catch fleeting molecules.  The bigger particles remain in the pores of charcoal. Electrostatic magnet pulls some substances through the pores. Some of the substances respond chemically with the charcoal and get attached to it.

Now a day’s most of us are spending more time in our homes for various reasons. Anyhow, your home is the place where you just relax and have a peace of mind. But most of the people neglect the fact that air quality in our homes is as crucial for our health as it is outside.

If you inhale the small microbe sized particles that your indoor air contains some times, then you may have some serious health issues. Like allergy or flu besides other significant wellbeing conditions. The technology has advanced so much that it allows you to sanitize the air that we breathe in our homes also. For this you have to have an air purifier. Here are some genuine reasons for you to get one.

Multiple Chemical Sensitivity:

This chemical sensitivity happens when a person is exposed to a chemical that exists in air for a longer period of time. Our normal household smells such as detergents, sprays and bleach can also bring down the quality of indoor air. And can result in pulmonary irritation if you are sensitive. An air purifier improves indoor air as it strains such chemicals from the air. Allowing you to breathe pure air at your house.

Smells/ Odours:

There are many reasons for smell to come and it comes from different places. This happens in old and abandoned houses or those that have been damaged by floods etc. In these cases the odor of wet wood rot is present in the air. An air purifier is capable of distilling the air and throws away any unpleasant smells in your home. To make you feel comfortable while breathing.

Small children:

As we all know that children’s immune system keep developing day by day they are more prone to allergies. With the help of an air purifier,it’s likely to shield your children from the particles present in the air. That can harm your children’s wellbeing.


We all love our pets and want to spend time and play with them. We keep them clean also as it helps to minimize the risk related with their falling hair and dead cells. The problem still lingers for people who have allergies as it is hard to continuously nurture our pets.

It can slowly develop within the lungs of the people who keep the company of pets. Air purifiers allow you to play with your pets as it clean out all these harmful particles and protect your family.

You have a home office:

Everybody is working from home and spending time on computers. But most people don’t know that computers do release fumes and dust as they run. So when you are working continuously you need to have clean indoor air quality. Therefore an air purifier can defend you from air pollution caused by the computers. And you can work easily without feeling exhausted

If you are the one who is concerned about your wellbeing, then you must be thinking about the air also that you breathe. Pollutants and allergens are filled in the air in indoors most of the times. In this situation an air purifier can help you out. But for this you have to pick the right one. But the question is How to choose an air purifier?

Decide in which room you will be using your purifier so measure the size.

Pick the right kind of flirtation as they have specific filters for specific needs, like smoke, asthma and pets.

Some of the air purifiers make noise so be prepared to live with it.

No matter what the manufacturers say about the purifiers, the fact is they cannot remove all the pollutants and allergens from your house.  The purifier can only clean the air that goes through it. Allergens and pollutants can stick to hard surfaces. And can come back into the air.

There are certain things to keep in mind beforebuying an air purifier to make sure that you get the great performance.

Compare the CADR ratings as it is very important.

Buy an air purifier with HEPA filter technology.

Check the noise rating and get with the minimum noise rating if possible.

Examine the cost of renewing filters and maintenance.

Make sure whether you want to use your phone for putting on and off the purifier. 

CADR (clean air delivery rate) its importance:

The greater the CADR number mentioned on the air purifier, the more accurate the filter will clean the air. For the big room you need the larger CADR number. There is no standard set for the CADR number as related to the size of the room. Most of the times the makers will suggest the room size on the packaging itself.

Health Benefits of Air Purifiers:

Air purifiers can reduce contamination of harmful particles, and they are useful in both commercial and residential environment.

Reduce the chance of asthma attack:

 AS there is a high number of asthma triggers are present inside houses or offices, air purifiers may be necessary in purifying the air of such triggers. Those that are designed to pull out tiny airborne particles are best fitted for narrowing the chance of an asthma attack.

Best Air Purifiers in India

Nowadays owning an air purifier makes a lot more sense because of the alarming level of increasing air pollution in almost every metro city in India. 

Generally we ignore most of the things but ignoring our own health and the health of our loved ones we are developing a major risk of developing respiratory disorders and it can be potentially very harmful for us.

Already a large number of people are suffering from respiratory problems. Hence its the need of the hour that we have to own a air purifier for us and for protecting the health of our loved ones.

The range of different air purifiers comes in a wide variety with different features, but while searching the product for one selves we only decide to buy the best .

There’s are different products comes with different sets of features like one of the basic air purifiers are the ones those can be run just by clicking some buttons and it will only cleans the air around but a air purifier is not only have that single feature in it its lot more than that .

According to our research there are mainly 5 types of air purifiers.

1.) HEPA Technology 

2.) Activated Carbon Technology 

3.) UV Technology

4.) Negetive Ion

5.) Ozone

1.) Hepa Technology- HEPA is an abbreviation for High Efficiency Particulate Air and is an innovation that has been utilized for a long time to channel particles.    

HEPA channels should satisfy a guideline of catching at any rate 99.97% of all particles bigger than 0.3 microns.

The natural eye can just see particles bigger  than 10 microns; so particles trapped in a HEPA channel, for example, synthetic substances, microorganisms and infections can’t be seen. Since HEPA channels can trap form and microorganisms,

They establish a more sterile climate. Moreover, this kind of air purifier doesn’t produce ozone or some other unsafe side-effects. 

HEPA Filter 

The HEPA channel is an extremely fine fiber-like material that has been collapsed to and fro to make the state of an accordion.

This accordion shape makes a labyrinth     of haphazardly organized strands and presents an enormous surface for air to be pushed through by the air purifier fan.

Wind stream should have a chance to go through     the channel with the end goal for it to be cleaned.

2.) Activated Carbon Technology Carbon Filter

Activated carbon is a type of carbon that has been handled to make it amazingly permeable and to give it an enormous surface zone for assimilation. 

 The utilization of actuated scientific ages back to the mid 1900’s the point at which it was sold economically to sanitize water and to remove the tone from sugar.    

During WWI, it was found that it very well may be utilized in gas veils to ensure officers, just as for war time water and air purifiers. 

Enacted carbon channels are included numerous atomic estimated pores that have high spongy capacity and substance holding.

These properties make them a compelling instrument for catching contaminations, for example, compound discharges, gases, tobacco smoke and scents.

When these contaminations are caught, they are not delivered once again into the air, dispensing with reintroduction of pollution. 

Air purifiers with enacted carbon channels are especially useful to individuals with Multiple Chemical Sensitivity (MCS) since they assimilate formaldehyde, which     is found in rug, wood framing, and furniture upholstery.

Scents, just as synthetics in family cleaning things are likewise eliminated, making the climate significantly     more breathable, particularly for asthma victims, infants, kids, and the older.

3.) UV Technology 

Air Purifier with UV Lamp UV innovation is regularly utilized related to particulate channel frameworks since it doesn’t actually dispose of airborne particles.

It is be that as it may, a phenomenal technique to eliminate germs, for example, microbes and infections.

Air purifiers utilizing this innovation have an UV light introduced and as microorganisms pass by the UV beams emanated from the light, cell or hereditary harm happens, obliterating the microorganism.    

An UV air purifier can change over particles of oxygen and water found in your air into ozone and hydroxyl. The dynamic particles respond with the air toxins and annihilate them into innocuous segments like water and carbon dioxide.

Ozone isn’t required for cleaning and since it tends to be a hurtful contamination, a decent UV air purifier ought to limit or take out ozone.

The adequacy of this sort of air purifier is reliant upon the wattage of the light and the hour of openness to the light. The UV light ought to be observed and supplanted by the maker’s proposals.

4.) Negative Ion 

Negative particle air purifiers utilize substance infusions to clean the air. A particle is a characteristic molecule with either a positive or negative charge.    

They get this charge be either acquiring or losing an electron. Negative particles are just oxygen molecules that have acquired an electron.

They attractively pull in airborne particles, for example, dust and residue, until the recently shaped molecule is too weighty to even consider staying in air.

This makes the molecule drop   and connect itself to another strong thing in the room, for example, a window or a divider. 

Albeit this innovation may appear to be progressed, it has demonstrated to be less successful than other air purifier advances.

Negative particle air purifiers simply   cover the dirtied air rather than really cleaning it. Shockingly, this kind of air purifier doesn’t can retain or discard the destructive toxins noticeable all around. 

5.) Ozone 

Ozone air purifiers purposefully produce the gas ozone (O₃). Albeit numerous assertions are made to unveil the accept that these gadgets are protected and powerful in controlling indoor air contamination, wellbeing experts have discredited these cases and no organization of the government have endorsed of these gadgets.

Openness to ozone may touch off asthma manifestations and a sufficiently high level can even scar the lungs.    

There are numerous brands of ozone air purifiers available and they all shift in the measure of ozone they can create.

A large number of the synthetic compounds found   in indoor conditions require months or years for ozone to respond, making them for all intents and purposes incapable.

Likewise, ozone doesn’t eliminate particles, for example, residue and dust so most ozone air purifiers additionally incorporate negative particle innovation, which as examined above, just covers the air instead of really cleaning it.

So now we can assurely say that all of our readers are well informed about the types of air purifiers that are available in the market and so we have created a list of  9 best air purifiers in India 2021 are:
