The United States Environmental Protection Agency (EPA) recently implemented the Pollution Prevention Act under the National Pollution Prevention Policy. The policy aims at preventing or reducing pollution at the source whenever feasible and recycling pollution that cannot be prevented in an environment-friendly manner whenever feasible. Similarly, the Air (Prevention and Control of Pollution) Act, 1981 was enacted by the Government of India to prevent, control, and abate air pollution. Likewise, the European Union (EU), has drafted the Ambient Air Quality Directive to control ambient concentrations of air in the EU.

Thus, the increasing implementation of air pollution control laws is expected to drive the liquid and air filter bags market at a CAGR of 6.5% during the forecast period (2018–2023). Additionally, the soaring number of water pollution prevention laws and wastewater treatment legislations will also fuel growth in the market revenue from $4,220.2 million in 2017 to $6,144.9 million by 2023. For instance, the Water (Prevention and Control of Pollution) Act, 1974 was enacted by the Government of India for controlling and preventing water pollution to maintain or restore the wholesomeness of water in the country.

The bag size segment of the liquid and air filter bags market is classified into 4OD*8'', 4OD*14'', 7OD*17'', 7OD*32'', and others. Under this segment, the 7OD*32'' category generated the highest revenue in 2017 as these are long filter bags that have low cost, superior product quality, and exceptional chemical compatibility. Whereas, the 4OD*8'' category is expected to showcase the fastest growth during the forecast period. Emirates Industrial Filters Ltd., Eaton Corporation, FILPRO Corporation, CLARCOR Inc., and DuPont de Nemours are some of the leading producers of liquid and air filter bags.

Geographically, Asia-Pacific (APAC) accounted for the largest share in the liquid and air filter bags market in 2017 due to the increasing implementation of emission control regulations and the requirement for clean indoor facilities in the region. Moreover, the rapid economic development, owing to the prospering power, food and beverage, and oil and gas industries, in APAC nations, will also drive the demand for liquid and air filter bags in the region in the forthcoming years. Nearly all countries in the region are investing huge sums in power and pharmaceutical industries to meet the high electricity and medicine demand, respectively, of their populace.

Therefore, the surging need to comply with air pollution and water pollution prevention laws, owing to the worsening water and air quality, will boost the adoption of liquid and air filter bags in the coming years.
