Segment Insights

Type Insights

Why Did the Packed Bed Filters / Activated Carbon Filters Segment Dominate the Market?

The packed bed filters / activated carbon filters segment dominated the gas phase filtration market with the largest share of 65% in 2025. This is because of their effectiveness in eliminating volatile organic compounds, odors, toxic gases, and corrosive contaminants in industrial and commercial environments. Packed bed filtration systems have a high adsorption capacity and are easy to use and cheaper than others, making them the preferred choice in manufacturing plants, wastewater treatment facilities, chemical industries, and HVAC systems.

Moreover, activated carbon filters are versatile and can be tailored to meet the needs of a particular contaminant removal, which serves a variety of end-use industries. Adoption of these filters is further increased due to increasing regulatory pressure on the control of air safety and emissions.

The combination filters segment is expected to grow at the fastest CAGR of 4.6% in the market between 2026 and 2035. This is because these systems integrate both particulate and gas-phase filtration, allowing simultaneous removal of airborne particles and gaseous pollutants in a single unit. This dual functionality is ideal for modern facilities that require compact, energy-efficient, and high-performance air filtration. Additionally, combination filters simplify installation, reduce maintenance needs, and are widely adopted in commercial buildings, healthcare facilities, laboratories, and high-tech manufacturing environments, further driving market growth.

Filter Media Insights

What Made Granular Activated Carbon the Dominant Segment in the Gas Phase Filtration Market?

The granular activated carbon segment dominated the global market with a share of 65% in 2025 because of its high adsorption capacity and massive industrial uses. Granular activated carbon (GAC) is a very efficient method of capturing volatile organic compounds, sulfur compounds, solvents, and odorous releasing gases in air streams. It has a high surface area, is chemically stable, and relatively cheap, which makes it attractive as a filtration medium in the chemical, pharmaceutical, food processing, and wastewater treatment industries. Its dominance in the market is further reinforced by the increased use of HVAC air purifying systems and the rising use of industrial emission control technology.

The potassium permanganate/chemisorption media segment is expected to grow at a CAGR of 4.4% between 2026 and 2035 because of the rising demand for high-performance chemical filtration solutions. In contrast to physical adsorption media, chemisorption media react chemically with the harmful gases, thereby effectively removing highly reactive or corrosive contaminants, such as hydrogen sulfide, formaldehyde, and nitrogen oxide. Chemisorption media is also being used in industries that use sensitive electronic equipment, cleanrooms, and data centers to avoid the damage of such equipment due to corrosion. These specialized filtration materials are increasingly being used in semiconductor production and high-tech plants.
