In 2020 the global air purifier market was valued at $10.38 Bn US and is projected to reach $21.15 Bn by 2027, with a compound annual growth rate of 10.7% over the seven years according to the Brand Essence market research reports.

According to the Health Effect Institute, air pollution is responsible for between 4.9 Mn and 8.8 Mn death around the globe each year and indoor air pollution is becoming a serious concern with more people spending time at home or inside.

PM 2.5 are able to get indoors through car engines and fireplaces, as well as in coal or natural gas, indoor ventilation can build up PM 2.5 particles more than outdoor environments.

PM 2.5 are pieces of particulate matter with a width of two and a half microns or less.  Such particles are increasing due to natural disasters like wildfires becoming more prevalent and are the main cause of smog in urban areas.

They can cause increased blood pressure, complications in pregnancy and other negative health impacts.

As such, there is a growing demand for air purifiers and air systems, especially in urban environments, with increased regulatory measures being taken to ensure safe environments for workers in the industrial sectors leading to continual growth in the air purifier market.

Studies suggest that portable air purifiers could reduce the invasion of PM 2.5 particles by an average of 22.6-92%.

Innovation along with continual research and solutions is key to the growth of the air purifier market; whereas before technology costs prevented new businesses entering the industry, the increased demand and wider availability of private funding has allowed more new players to enter the market.
