Air Purifier Market Size, Share, Growth, Trends, and Global Industry Analysis: By Technology (High-Efficiency Particulate Air (HEPA), Activated Carbon, Ionic Filters, and Others), By Application (Commercial, Residential, and Industrial), and Region Forecast 2020-2031    

Air Purifier Market size was valued at US$ 17.1 billion in 2024 and is expected to reach US$ 27.6 billion by 2031, growing at a significant CAGR of 7.1% from 2025-2031. An air purifier or air cleaner is a device that removes contaminants from the air in a room to improve indoor air quality. These devices are commonly marketed as beneficial to allergy sufferers and asthmatics, and to reducing or eliminating second-hand tobacco smoke.

The market is primarily driven by increasing pollution levels in urban areas which leads to increasing airborne diseases. Apart from this, rising health consciousness, coupled with the improving standard of living and increasing disposable income, is further expected to boost market growth. During COVID-19, various lockdown measures were implemented by governments across the world, which resulted in boosting the sales of home appliances such as air purifiers, cleaning appliances, kitchen appliances, and water filtration devices.
