Pollution kills! While air pollution causes asthma, bronchitis, lung cancer, and chronic obstructive pulmonary disease, water pollution is responsible for diarrhea, gastroenteritis, and cholera. This is why governments around the world are swinging into action and implementing stringent emission- and effluent-control regulations on industries. As a result, factories are installing additional equipment which cleans the exhaust and liquid effluents, before they are discharged into the atmosphere and waterbodies, respectively. One of the most effective ways to control what goes out is simple filtration.

Thus, with the concerns regarding the adverse impact of pollution increasing, the liquid and air filter bags market is predicted to grow from $4,220.2 million in 2017 to $6,144.9 million by 2023, at a 6.5% CAGR during 2018–2023 (forecast period). Between air and liquid filter bags, those that separate liquids are used more, as these bags are not only required to curb water pollution, but filter a wide range of fluids during the manufacturing process. They find wide application in the oil, bitumen, adhesives, chemicals, food, resins, petroleum, and paper sectors, apart from water treatment.

Globally, Asia-Pacific (APAC) accounts for the highest usage of these bags, as a result of the strict emission control policies and requirement for clean air in indoor spaces. Additionally, with the expansion of the food and beverages, power, construction, mining, and oil and gas sectors, as the result of the swift urbanization and industrialization, the liquid and air filter bags market is expected to keep growing in APAC. The surging pharmaceutical production is also playing a part, as these bags are extensively used for recovery of the catalyst and active ingredients, purification and removal using activated carbon, and filtration of gelatins.

Hence, with the growth of industries, in an era when air and water pollution are serious issues, the demand for liquid and air filter bags would keep increasing.
