Air pollution from both stationary and mobile sources includes many harmful primary and secondary pollutant substances. Primary pollutant substances such as carbon monoxide and lead react with each other and form secondary pollutants. AMSE is widely used in industries to monitor such air pollutants in order to meet the stringent environment-related regulations from several governments. Air sampling equipment detects various gases and particulates in the ambient air while air monitoring equipment collects the accurate real-time measurements of pollutants. The data collected is used to define the nature and severity of pollution. The data also helps take necessary preventive actions from any disasters in the plants. In addition, AMSE is used to identify pollution trends and develop air pollution models, helping end-users track the air pollution level. The Global AMSE market is witnessing growth potential from both developed and developing countries. Majority of the market growth stems from the APAC region, followed by the Americas and the EMEA region. In 2012, the market generated more than 40 percent of its revenue from the APAC region. The Global AMSE market is expected to grow at a CAGR of 20.17 percent during the period 2012-2016.

An air filter is a device used to purify air from unwanted waste materials (such as dust) and microbes present in the air. Most of the air filter consists of a filtering material, a sealant, a frame, a faceguard, and a gasket. Air filters are used by various end-users such as commercial buildings, residential buildings, and several industries including Electronics, Bio-clean, Power, and Metal industries.The Global Air Filter market is expected to grow at a CAGR of 4.78 percent during the period 2012-2016. The Global Air Filter market generates large part of its revenue from the developed countries such as the US and the UK. The increasing government regulations on environment protection especially by the European Union have also led to the increased demand for Air Filters in the global scenario.
