Buying Guide

for Best Air Purifiers in India

Why do we need Air Purifiers?

In most cities, people spent about 90% of their time indoors. So Indoor air quality is extremely important. While large pollutants are visible by our naked eyes particulate matter or PM made up of very fine solids or liquid particles are not possible to be seen by naked eyes. Their size is almost 20 to 100 times thinner than a human hair.

In enclosed spaces due to poor ventilation, these particles do not have an exit route so they remain inside.

These particles when move into our respiratory tract and penetrate deep in our lungs can cause severe damage. They can consequently enter our bloodstream from the lungs, which can be very dangerous.

Let us understand indoor air pollution better and make the right choice as per our needs.

What is indoor air pollution?

Indoor air pollution is the depletion of the quality of air in an enclosed area. Indoor air pollution is a very real thing unlike many of who believe only outside air is polluted, the air inside any household is far more polluted than outside air.

The indoor air is more concentrated with pollutants due to poor ventilation. There are many sources of indoor pollutants and they vary from developing countries to developed countries.

The major contributors to indoor air pollution are airborne particulate pollutants like pollen, spores, fungi. The size of these particulate pollutants is in the range of 0.04 micron to 100 microns (a micron is 1/25000 of an inch). For this kind of impurity, the HEPA filter is the best choice.

Then we have Tobacco smoke one of the primary cause of indoor. Second-hand smoke can cause many health problems just like active smokers.

Household gases and VOCs are a huge contributor to indoor air pollution. These harmful gases are emitted by varnishes, paints, disinfectants, glue, and adhesives. These VOCs include benzene, toluene, formaldehyde, and ethylene. Inhaling these VOCs can cause severe health problems.

Household cleaner sprays air freshener, etc add to indoor air pollution. They can be tackled by an activated carbon filter.

All these pollutants have adverse effects on human health, including headaches, respiratory problems, frequent colds, and sore throats, chronic cough, skin rashes, eye irritation, lethargy, dizziness and memory lapses. Their long term effects are even more dangerous. They increase the risk of cancer.

Almost every household or office space is potentially at danger of increasing levels of one or more of these indoor pollutants like nitrogen dioxide, carbon monoxide, hydrocarbons, formaldehyde, radon (a radioactive product of radium), sulphur dioxide, asbestos, chemicals in hairsprays, deodorants, household cleaners, paints, pesticides, laundry aids, floor and furniture polishes, glue and, ironically, air fresheners.

Though babies, children, and the elderly are at higher risk of developing ailments like asthma, respiratory problems, heart, and lung problem, these aliments can occur in otherwise healthy individuals also.

 Let us understand a few technical terms that you will encounter when searching for an air purifier.


Best Air Purifiers in India

PM stands for particulate matter and 2.5 is the micron size. 1 Micrometer (micronis equal to 0.0001 centimeter (cm). So PM2.5 basically means any impurity in the air which is of size 2.5 micron or smaller. This small size impurity in the air is impossible to be seen by the human eye. Dust, spores, and pollen are some examples.


Similar to PM2.5, PM10 means a particulate matter of size 10 microns or less. Comparatively, they are larger particles however when inhaled over a prolonged period they can also cause severe damage to the human body.


CADR stands for Clean Air Delivery Rate. So basically it tells how fast an air purify can clean air within a particular area. Higher the CADR more effective is the purifiers.



This is the first line of defence in air purifiers. It is similar to the net filters you must have seen in air conditioning units. They are either made up of very fine polyester net or a fine foam sheet. They are capable of trapping only large particles like hair.

Hepa Filter

Best Air Purifiers in India

Hepa stands for High-Efficiency Particulate Arrestance/Adsorption/Air. This is the most advanced technology in the air filtration system.  Even though HEPA is the most advanced technology it was developed in 1940 during the Manhattan Project. Its primary object then was to protect scientists by collect all the radioactive particles that turned airborne during the experimentation process.

Over the years HEPA filters have evolved. These filters mainly collect particulate matter through an air filtration system that can capture up to 99.97% fine airborne particles that are larger than 0.3 microns.

HEPA filters are capable of eliminating viruses, bacteria, airborne fungi,  pollen, human hair, and particulate matter (such as smoke particles, pet dander, and dust) from the air in any closed space.

To put it simply, HEPA filters trap air contaminants in a complex web of fibres. These airborne impurities are captured by these filters in four different ways: Inertial Impaction, Diffusion, Interception, or Sieving.


  • Highly efficient, capture most of the toxic contaminants
  • Trapped particles will stay within the air filter
  • The physical air filter won’t emit ozone, which causes asthma and other breathing issues


  • Requires routine filter replacement to maintain the efficiency
  • Doesn’t remove odours and smell

Ionizers and Ozone Generators

The Ionizers filter generators release charged ion particles in the air. These charged particles then cling on to dust or particulate air pollutant and make them fall down because of their weight.

Ozone filters also work on similar principles however they release a small amount of ozone which is not very good for health and the environment.


  • Maintenance-free, without filter replacement
  • Can even remove some bacteria and viruses


  • Small amounts of ozone as a by-product which can irritate asthma and respiratory issues
  • Doesn’t remove odours and smell
  • Higher power consumption

Activated Carbon

These filters use a special kind of activated carbon particles that have millions of tiny pores that can absorb and neutralize harmful gases, VOC’s odour. These activated carbon particles have the potential to trap large pollutant particles in them. 

Therefore these filters do not remove contaminants from the air instead just trap them in their tiny pore. For this reason, these filters are never be used alone. However, they are very effective in eliminating odour and other gaseous pollutants from indoor air.


The only air filter to remove chemicals, gases, odours and smells from pets, cooking, smoke, paints and cleaning supplies


  • Needs other air filters cannot work alone effectively
  • Needs to be changed frequently


UV stands for ultraviolet. These UV filters emit ultraviolet light (UV-C type)which cannot be seen by the naked eye because it is part of the invisible spectrum of electromagnetic waves. UV light is a powerful form of radiation that is not harmful to humans.

These filters are extremely effective in killing germs. How it works is that air is passed through the air purifier after all other filters then the air is exposed to UV light. This process sterilizes the air passing through it.

It is highly recommend for family with babies and aging elders.


  • Can kill the microorganisms such as germs, bacteria and viruses
  • The UV-C light causes no harm to humans


  • Still produces ozone
  • Requires Frequent change.
  • High Power consumption
  • Can’t remove the actual particles from the air

How to Choose the Best Air Purifies in India

There are many brands and models available today in the Air purifiers segments This makes the decision making process even more difficult. We have created a quick checklist that you can use to choose the Best Air Purifiers for your home.

  1. What is the size of the Room you want to buy the purifiers for? (Think CADR and Air Purifiers capacity)
  2. Do you wish to use it in multiply rooms? (Portability)
  3. Cost of maintenance?(Filter Replacement/AMC cost)
  4. Do you have Kids/babies or elderly or light sleepers in the house? (Child Lock and Noise levels)

Size of the Room and Air Purifier

The size of the room and the air purifiers is a very critical point to consider. It is imperative that the two match. So, carefully measure the room you are planning to buy air purifiers for before buying one.

For any device/ appliance to work effectively we need to ensure that it is working as per its capacity. If an air purifier is designed for a certain size room then one can only use it either for that size of the room or smaller. In case a smaller size air purifier is kept in a large room it will not be able to do its job properly.

Thankfully, all Air purifiers come with a display option to show the air quality of the space it is kept in. In case you feel the air quality is not improving try putting it in a smaller room and see the difference.


The Clean Air Delivery Rate or CADR tells about the speed or rate at which an air purifier can clean air in a particular area. It is measured in Cubic Meters per hour (m3/h) or cubic feet per minute (CFM). The higher the CADR, the better is the performance of the air purifier.

This rating was developed and created by AHAM i.e Association of Home Appliance Manufacturers.


ACH or Air Change per Hour. This is an important factor to consider. It basically tells how frequently the air purifiers can completely change the air of a room.

So an air purifier with ACH rating of 5 will change the air in the room 5 times in one hour.


In case you decide to use the air purifiers in multiply rooms do keep in mind the weight of the machine and the length of the cord. Some air purifiers come with caster wheels making it easier to room from one room to another.


The noise from the air purifiers is mainly due to the fan speed. This fan speed can be adjusted as required. Almost all air purifiers come with silent mode for night time.


Its always good to have your product covered for a longer period by the manufacture. Who knows when you may need them. Even the best brands do not have 0% manufacturing defect and you don’t want to be stuck with a defective machine.


The price range varies hugely in the air purifiers segment. Choose as per your budget.

Cost of Maintenance

Now, this is a recurring cost. Keep in mind that all air purifiers have filters that need to be replaced from time to time. Although the frequency of replacement depends on the quality of the filter and also on the pollution levels of the city you live in. You could opt for AMC for hassle-free functioning.
