8 Best Air Purifier in India: 2020 Reviews & Buying Guide

According to Indian Journal of Community Medicine, indoor air is 5 times more polluted than outdoor air – because of poor ventilation and gases emitted by perfumes, stoves and other household electric appliances.

Air purifiers help in removing the pollutants present in indoor air. These electrical appliances are very important for those suffering from asthma, allergies, or other respiratory issues.

Since each model of air purifier target different types of air pollutants, it is very important to buy the right kind of air purifier for your home. These factors can be helpful to you.

Filter Type:

There are 4 types of filters used majorly in air purifiers: HEPA, Activated Carbon, UV & Ionic. Each filter addresses a different type of air pollution. This table can help you to select the one that suits your requirements.

Filter TypeBest to Remove
HEPA (High Efficiency Particulate Air)Pollen, mold spores, fungi, dust, pet dander, hair,
mold spores, and visible smoke
Activated CarbonChemical and gas fumes, odors and smells from pets,
cooking, smoke, paints and cleaning supplies
UVBacteria, viruses and germs
IonicDust, pollen, mold spores, fungi, volatile organic compounds,
some bacteria and viruses, and visible smoke


CADR measured in cubic meter per hour. It helps you understand how effective it is in removing dust, pollen, and smoke from the air.

In India, you can see only one CADR figure i.e. the smoke CADR. CADR above 240 is considered good at removing pollutants/particles of that size range.

Coverage Area:

Air purifiers are rated with coverage area (square feet). Before buying one, measure your room and select a model that offers coverage area a bit more than the actual size of the room.

Note: An ideal air purifier should have at least a 4-6ACH rating. If you are suffering from asthma or other respiratory issues, the ACH rating should be around 6-8. To learn how to calculate ACH based on the room size and CADR, check our “Buying Guide“.

We have shortlisted some of the Best Air Purifiers available in India. Let’s check them out.
