Having good air purifiers at home can not only take care of the polluted air at home but it also helps in improving the quality of living.

A lot of people actually believe that the air in their home is better than the air outside their homes. But the bitter truth is that is no better and it is as polluted as the air outside your home is.

The only difference is that the pollutants are different than they are outside. When you go outside and think of air pollution what comes to your mind? pollution from the vehicles on the road, Big chimney and all sort of polluting agents, right?

And when you think about air pollution inside your home, what comes to yours. mind? Nothing really, right? That is because we are not aware of the things inside our that can actually pollute the air.

In fact, there are many other factors that can cause air pollution at home. For instance, the air conditioners and refrigerator emit quite harmful gases that are not only harmful to humans but are harmful to the ozone layer of the earth too. Another example of polluting factors at home are the deodorants and talcum powers used at home.

How to Buy the Best Air Purifier

As I mentioned earlier how important it is to have the best air purifiers in our homes, now here is how you can get one. Before buying an air purifier you will have to learn some basics about air purifiers as when you go to buy something you should know what you are looking for.

To avoid confusions and dilemma you should have basic knowledge about the product you are looking for and how they work. An air purifier basically consists of filters, to filter the air.

They are made of many keyers of filters to purify the air for us. On the technical level, there are 4 types of impurities. And they are Airborne particles, Tobacco smoke, Household gases, Volatile Organic compounds. Here is a brief explanation of what these terms mean.

Airborne particles

Airborne particles involve pollens, animal dander, spores, fungi, moulds, dust mites etc. These particles are quite small and the size of these particles can range from  0.04 microns to 100 microns. If you do not know how much a micron is then it is the 25000 part of an inch. The recommended filter to clean these airborne particles is HEPA filters.

Tobacco smoke

Although the consumption of tobacco by smoking has reduced over the few decades it will not be wrong to say that these habits still prevail in Indian households. Tobacco smoke is one of the leading causes of indoor air pollution and is really bad for everybody’s health.

Household gases

Household gases are one of the most common causes of indoor air pollution in India. Various household gases that can cause indoor pollution are pesticides, carbon dioxide, various gases that are emitted after burning something.

The best air purifiers to cope up with these pollutants are the one with activated carbon fibres.

Volatile Organic compounds

Volatile organic compounds or VOCs can be found various household things like disinfectants, paints, glues, adhesives and varnishes. The VOCs contain benzene, toluene, formaldehyde, and ethylene. And inhaling these can sever health complication that you definitely want to avoid.

To tackle these impurities you will have to install air purifiers with various functions. But before anything else, here are some basic and common terms associated with air purifiers. Read the brief explanation given below to have an understanding of these terms.


Pollutants that are there in the air are of different sizes and one of them is PM2.5. PM2.5 are those particulate matters that have the diameter less than 2.5 micrometres.

If you want to understand in simple terms then it is 3% of the thickness of human air. They are so small that we can not see them with our naked eyes but they are present in the environment. If inhaled on a regular basis, they can cause severe health problems in humans.


These are also another kind of particulate matter. Like PM2.5 is particulate matter that has the diameter of 2.5 microns or less, this is a particulate matter with a diameter of 10 microns or less.

They are comparatively larger than PM 2.5 and very dangerous if inhaled on a regular basis.

Clean Air Delivery Rate or CADR

In simple terms, CADR refers to how fast your air purifier works. As far as air purifiers are concerned, there are various CADR numbers for different pollutants like pollens, dust, smoke etc.

The thing you need to know is the higher the CADR of the air purifier, the better the air purifier is. The terms that are used are in cubic feet. You should see how many cubic feet the air purifier can in a minute. The figures are also available in cubic meter per hour.


HEPA or High-Efficiency Particulate Arrestance/Adsorption/Air is a kind of a filter that is found in the best air purifiers. The job of HEPA is to trap dust and dirt particles. There are generally various ways to trap dust and dirt particles.

These ways are inertial impaction, diffusion, interception, or sieving.

It is important that the air purifier that you are looking for has a HEPA filter in it. Other than HEPA there are other kinds of filters like activated carbon filters, ion and ozone generators, and pre-filters. 


These are basic and the first most layer of resistant for the pollutants in the air.

These filters are quite common and are found in air-conditioners too. They are usually made of foam or some kind of non-woven polyester material.

Their job is to trap the larger particles of dust, animal hair, and other pollutants present in the air.

Activated Carbon filters

The main job od the activated carbon filters is to trap VOCs and false odours that are emitted due to different gases present in the air. They work by absorbing odours and obnoxious gases and neutralize them.

When you look for an air purifier remember that the larger the activated carbon filter the better the air purifier. You should keep in mind the fact that one pound of activated carbon has a surface area of around 60 to 150 acres and buy your ait air purifier according to it.

Ion and Ozone generators

These generators work by generating ions. Ions are charged particles which this generator generates and release them into the air.

The ions stick themselves to the pollutants and weigh them down due to their weight. Same happens with ozone but the only drawback is that excessive ozone can be toxic for your health.


HEPA filters are quite important in an air purifier that you choose. It makes sure that the pollutants are removed from the air. That is why all the air purifiers that are there in this list have HEPA air purifier. The air purifier that got the first position in this list is Dyson Pure Cool Link Tower WiFi-Enabled Air Purifier, TP03. It is one of the best air purifiers that you are going to get if you go out looking for air purifiers. The only drawback to this air purifier is that it is a bit on the expensive side and not everybody can afford it. Although, the other air purifiers that are on the list are equally good and you can definitely go for them.
