Air Purifier Buying Guide

Let us now see what constitutes indoor pollution.

You use deodorants and talcum powders in your home. Inhaling the air contaminated by these chemicals is dangerous. You have air conditioners and refrigerators emitting harmful gases.

Insect repellents constitute an important constituent of indoor air pollution. You have an emission of hydrocarbons when you light up incense sticks and camphor.

There are animal dander and pollen to contend with. Detergent powders and toilet cleaners are also sources of indoor air pollution. The list can be endless. The prime reason is that indoor air does not have a means to escape to the exterior. Therefore, it makes sense to use air purifiers at home.

We have already seen how the indoor air can be as impure as the outdoor air, if not more. Are you surprised at this fact? There is no need to be because we shall now list out the impurities that you would encounter indoors.

Airborne particles Tobacco smokeHousehold gasesVolatile Organic compounds

This includes pollen, animal dander, spores, fungi, moulds, dust mites, and so on. The size of such particles can range from 0.04 microns to 100 microns. Remember, a micron is equal to 1/25000 of an inch. The HEPA filter is the best appliance to take care of such airborne impurities.

This is one of the primary causes of indoor air pollution. Nowadays, the awareness levels have increased with many people quitting smoking altogether. However, tobacco smoke is still one of the prime irritants around.

It forms one of the most common indoor air pollutants. You have various toxins and other gaseous pollutants like pesticides, aerosol sprays, chemical cleaners, and so on. The best filter to take care of these impurities is the activated carbon filters.

The VOCs are found in various household items like varnishes, paints, disinfectants, glue, and adhesives. These VOCs include benzene, toluene, formaldehyde, and ethylene. Inhaling these VOCs can cause severe health problems.

You need special types of air purifiers to tackle these impurities. We shall discuss these aspects. But, prior to that, you need to be aware of certain commonly used terms as far as air purifiers are concerned. You will come across these terms virtually every time you open a discussion on air purifiers.


Impurities are of various sizes. PM2.5 refers to those particulate matter having diameter less than 2.5 micrometres. Roughly translated, it amounts to 3% of the thickness of a human hair. Particles of this size are not visible to the naked eye. But, they are present in the atmosphere. They can cause dangerous harm to the lungs and other organs of our body should we inhale them on a regular basis.


Just as PM2.5 refers to particulate matter having a diameter of 2.5 micrometres or less, PM10 refers to similar matter having diameter 10 micrometres or less. Comparatively, they are larger sized particles. They can also cause great harm when we inhale them.

CADR: Clean Air Delivery Rate

To put it very simply, CADR is a measure of how quickly the air purifier works. The resultant figure denotes how many cubic feet of air the air purifier can purify in one minute. You also have this figure in cubic metres per hour. The higher the CADR, the better is the performance of the air purifier. There are different CADR numbers for dust, pollen, and smoke as far as air purifiers are concerned.

HEPA: High-Efficiency Particulate Arrestance/Adsorption/Air

The principal job of the HEPA filter is to trap the dust and dirt. There are different ways of trapping the impurities depending on the size of the particle. These are inertial impaction, diffusion, interception, or sieving. It is imperative that the air purifiers have HEPA filters to perform successfully. All the ten air purifiers discussed above have HEPA filters.

Working of HEPA Filter

We have just seen that HEPA filters are one type of filtering appliances present in the air purifiers. There are a couple of more types of air filters such as activated carbon filters, ion and ozone generators, and pre-filters. Let us now look at these processes in brief.


This is usually the first line of resistance to the impurities. You much have seen examples of the pre-filters in AC units. They are either made of foam or some sort of non-woven polyester material. They trap the larger particles of dust, animal hair, and other impurities.

Activated Carbon filters

The principal responsibility of the activated carbon filters is to eliminate VOCs and the bad odour caused by different kinds of materials and gases. Activated carbon filters adsorb the odours and obnoxious gases and neutralize them. One pound of activated carbon has a surface area of around 60 to 150 acres. Therefore, the larger the carbon filter better is the performance of the air purifier. Once the carbon filter becomes full of impurities, you need to replace the same.

Ion and Ozone generators

These generators create ions (charged particles) and emit them into the air. These ions will cling to the impurities and cause them to fall down to the ground because of their weight. Similar is the case with ozone generators. The drawback is that inhaling ozone is not good for health. Secondly, an excess of ozone in the environment is harmful.

These are the different types of filters one normally associates with air purifiers. The impure air becomes fresh and pure after passing through these filters. Before deciding to purchase an air purifier, you need to look at these following factors.

Coverage area – Ensure that the coverage area of the air purifier is equal to or greater than the area of your room.

ACH ratings (Air change per hour) – This is a very important factor. It tells you how frequently the air purifier can exchange the air in a given room. For example, if you have a 20’ X 20’ room and an air purifier with ACH rating of 6, it entails that the air purifier is capable of exchanging the entire air in the room 6 times in an hour.

Price – It depends from model to model. You should also factor in the cost of replacing filters annually.

Energy Usage – Follow the BEE Star ratings in this regard.

Noise level – The noise level depends on the fan speed. The higher the fan speed, the noisier is the machine.

CADR – We have discussed this matter earlier.

Some Points To Note

More than Thirteen Cities in Our country are in the Top 20 Cities in the world with the highest levels of the Particulate Matter M 2.5.”

According to WHO, reducing air pollution levels can lower the burden of disease from Lung cancer, respiratory disease, Asthma and Heart disease.

More than 92% of the Globe Population were living in places having more Air pollution that causes 3 million premature deaths around the earth in 2012.


Indoor Air pollution which is caused by smoke released from cooking and burning coal or other biomass fuels is a serious health risk.

The Biggest impact of Air Pollution is on public health. Indoor Air is four times more polluted than the outside air, and average indoor air pollution in India is 375 grams/cubic meter of air. According to the World Health Organization, It should not be more than 20 grams/cubic meter.

Some of the common sources of Indoor Air pollution are cooking fuel, construction material, Smoking tobacco, Carpets, Pets and many other factors.

As I mentioned earlier, the PM 2.5 Particles can go deep into your lungs and can even get into your bloodstream. Short-term effects can be eye irritation, nose itching, and sneeze. But, continuous exposure to this PM 2.5 can be devastating, the impact will be more on children and older adults. Also, people who are having Asthma or Prone to Allergies are more affected by PM 2.5.

The Particulate Matter 2.5 or PM 10 are generated by burning fossil fuels like coal, petroleum, and other factory combustibles, The exhaust released by the Vehicles like Cars, Buses, Airplanes and Trucks, Industrial emissions, Thermal power stations, Toxicants released during the manufacturing of goods and many other factors.

Air purifiers are just a small bandage to the Big disease of Air Pollution that is growing at an Alarming Rate. We just can’t carry an Air Purifier everywhere we go!

Things we can do to Control Air Pollution at our Home


Most of the power generated in India is via Thermal Plants where they burn coal which is a major source for PM 2.5 and many other pollutants.


You can replace your Traditional Home Lights with LED lights that consume a lot less power, and you can also save some money.


If you are living in an Individual house, Do plant some trees. Also, If you Apartments have a balcony, Do plant some trees. These are the tiny things that we can do to control the Air pollution.


You might think It’s not significant. But, If Lakhs of us start planting trees at our home, then it can be a positive change.
