Top 5 Air Purifier Brands to Invest in 2021

Air Purifier Market Overview

With rising industrialization, urban congestion, and vehicular emissions, air pollution has become one of the most critical global health concerns. According to SAFAR (System of Air Quality and Weather Forecasting And Research), major metropolitan cities are recording dangerously high Air Quality Index (AQI) levels — in some cases touching 461 — far exceeding safe limits. The predominant pollutant, PM 2.5, poses severe health threats, including asthma, cardiovascular diseases, and reduced lung function.

As awareness about respiratory health and indoor pollution grows, air purifiers are transitioning from luxury items to household essentials. Urban consumers, particularly in metro and Tier-1 cities, are investing in high-efficiency models to protect themselves and their families from toxic air exposure. The global air purifier market has witnessed a significant surge in demand, with over 50% sales growth across major Indian cities and increasing adoption worldwide.

Why Invest in Air Purifiers?

Clean air is no longer a privilege — it is a necessity. Continuous exposure to polluted air can lead to chronic respiratory disorders, heart complications, and weakened immunity. Modern air purifiers are equipped with HEPA filters, activated carbon layers, and smart sensors that efficiently remove airborne allergens, microbes, and particulate matter.

The new-age consumer is prioritizing preventive healthcare and wellness, making air purifiers an ideal investment for ensuring long-term respiratory health.
