Air Purifiers for Room: A Complete Guide for Indian Homes

Why Air Purifiers Matter in India

Air pollution in India has become a growing health concern. According to the World Air Quality Report 2024, many Indian cities rank among the most polluted in the world. Prolonged exposure to polluted air can lead to respiratory issues, allergies, and long-term health risks. Since we spend more than 80% of our time indoors, investing in an air purifier for room is no longer a luxury but a necessity.

What Is an Air Purifier?

An air purifier is an appliance designed to clean the indoor air by removing pollutants like dust, pollen, pet dander, smoke, and harmful airborne particles. It uses filters and advanced technologies to ensure the air you breathe is clean and healthy.

Key pollutants removed by air purifiers:

Dust and particulate matter (PM2.5, PM10)
Pollen and allergens
Smoke and harmful gases
Pet hair and dander
Bacteria and viruses
