Buying Guide for Air Purifiers

It is very important to purify the air we breathe to avoid several health complications related to the respiratory system. Thus, it is recommended by doctors to install air purifiers at home. Now, before choosing one for your home, you need to carefully know the factors on the basis of which the air purifiers can be classified as excellent to good. Since this is an investment to be made which could be run long in the future. The various types of impurities that are present in the air both indoors and outdoors include smoke from vehicles, CFCs, tobacco smoke, pollens, animal dander, various household gases and a lot more. In order to remove these, air purifiers are designed with several technologies which are important to be checked before purchasing. Here is a guide to direct you through all the aspects that would help you choose the right appliance for you.

Firstly, you need to know the several terms that are used in the description of an air purifier. These are:-

a.    PM2.5: This term is used for the suspended particulate matters which are of diameter 2.5 micrometers. These particles are not easily detected by naked eyes. They are present in the atmosphere and cause harmful damage to the lungs.

b.    PM10: This refers to particulate matter having the 10-micrometer diameter. They are relatively large sized particles which cause harm when inhaled.

c.    CADR: This is the full form of Clean Air Delivery Rate which states the rate at which the air purifier works. The value displayed on the screen may denote the cubic meter of volume that is cleaned in one minute. The higher the CADR, the higher is the cleaning rate. There are different CADR number for different impurities namely pollen, dust and smoke.

d.    HEPA: Abbreviated as HEPA, High-Efficiency Particulate Adsorption is mainly responsible for trapping the dirt and dust in the air. It is basically a filter in the purifier. This filter traps the impure particles depending on the size of the impurities. Almost all the popular air purifiers in the Indian market are fitted with HEPA filters.

e.    There are two more filter types such as pre-filters and activated carbon filters that are used in an air purifier to filter the impure air in your room.

f.    Apart from these, there are ozone-ion generators, which create charged particles and emit them into the air. These charged particles get attached to the impure particles and make them fall to the ground under gravity. Similar is the case with ozone generators but however, inhaling ozone is also not good for health so it shall be avoided.

The impure air becomes fresh while passing through the filters and makes it pure for us to breathe in. But before buying an air purifier, have a look at the following factors.

v  It must be ensured that the total area of purification of the air purifier should be greater than or equal to the area of the room in which the purifier is being installed.

v   ACH (Air Change per Hour) rating is an important factor to be considered. It tells how frequently air is exchanged by the purifier in the room.

v  The price of the air purifier is also important to be considered. One should take into consideration the cost of changing the filter annually.

v  One should always check the BEE star rating before buying the air purifier.

v  The noise level of the purifier must be considered as well. The more the fan speed, the more will be the noise of the machine.

v   One should always check the brand in trend before buying the air purifier as it is a huge investment.


The effects of air pollution are adverse and its worst impact falls on the air purifiers. Surveys reveal that indoor air pollution four times riskier than the outdoor air pollution. Thus air purifiers are a necessity nowadays than a luxury. It is very important to breathe in the fresh air nowadays. Having checked all the above parameters, one can go for the air purifier of one’s own desire.
