The growth in the forecast period can be attributed to increasing investments in clean manufacturing environments, rising demand for advanced air purification systems, expansion of semiconductor fabrication plants, growing focus on indoor air quality control, innovation in high-efficiency sorbent materials. Major trends in the forecast period include expansion of gas phase filtration in industrial facilities, rising demand for corrosion protection solutions, growing adoption in semiconductor manufacturing, increasing use in healthcare air purification, enhanced filter material performance.

Rising concerns over air pollution are expected to drive growth in the gas phase filtration market. Air pollution, which contaminates the air with harmful substances, has become a major health and environmental issue. Gas phase filtration helps remove odors and gaseous pollutants in buildings, hospitals, workplaces, and other spaces without requiring modifications to existing HVAC systems. For example, in 2024, the World Health Organization reported that low- and middle-income countries experience 3.68 million premature deaths annually due to ambient air pollution - nearly eight times higher than the 0.47 million deaths in high-income countries. Consequently, increasing awareness of air quality issues is propelling demand for gas phase filtration solutions.

Leading companies in this market are developing portable gas phase filters to address localized air quality concerns in confined or mobile environments. Portable devices provide flexibility for residential, automotive, and small commercial applications. For instance, in January 2023, Panasonic, a Japan-based electronics and automotive company, launched the nanoe X portable in-vehicle air cleaner. The device removes odors and helps prevent viruses, germs, mold, and allergens both in the air and on surfaces, creating a healthier environment inside vehicles.
