Filtration and Contamination Control Market Report 2026

The filtration and contamination control market size has grown strongly in recent years. It will grow from $42.52 billion in 2025 to $44.71 billion in 2026 at a compound annual growth rate (CAGR) of 5.2%. The growth in the historic period can be attributed to expansion of industrial machinery usage, growth in automotive and heavy equipment production, increasing focus on equipment reliability, rising adoption of preventive maintenance practices, availability of advanced filtration technologies.

The filtration and contamination control market size is expected to see strong growth in the next few years. It will grow to $55.36 billion in 2030 at a compound annual growth rate (CAGR) of 5.5%. The growth in the forecast period can be attributed to growing demand for clean energy systems, increasing environmental regulations, expansion of industrial automation, rising adoption of predictive maintenance, growing focus on workplace air quality. Major trends in the forecast period include rising demand for high-performance air filtration systems, expansion of liquid filtration in industrial applications, growing adoption of oem-focused filtration solutions, increasing emphasis on contamination prevention, integration of smart monitoring technologies.

The expanding automotive industry is anticipated to support the growth of the filtration and contamination control market in the coming years. The automotive industry encompasses companies, organizations, and activities engaged in the design, development, production, marketing, and sales of motor vehicles. Contemporary vehicles increasingly emphasize passenger comfort and health by incorporating cabin air filtration systems that help maintain a clean, pollutant-free interior environment and deliver a healthier driving experience. For instance, in June 2023, a report published by Cox Automotive, a US-based automotive services and technology provider, estimated that car sales volume would rise by 11.6% annually to reach 7.65 million units in the first half of 2023. This growth was driven by new vehicle sales (1.1%) as well as repair and maintenance activities (0.8%). Unit sales in June were projected to increase from 1.1 million to 1.3 million. As a result, the continued growth of the automotive industry is contributing to the expansion of the filtration and contamination control market.

Leading companies operating in the filtration and contamination control market are emphasizing the development of innovative solutions, such as compact portable contamination monitors, to support faster on-site fluid condition assessment, predictive maintenance, and minimized unplanned downtime compared with conventional laboratory-based particle analysis, which is slower, less frequent, and reliant on sample transportation. A portable contamination monitor is a handheld or benchtop optical device designed to measure particulate and water contamination in hydraulic fluids, oils, and diesel in real time. These devices typically feature multi-channel particle sizing and counting, water-content detection, onboard data storage, and intuitive user interfaces that allow field technicians to conduct repeatable, standards-compliant assessments without the need for specialized laboratory support. For example, in November 2025, MP Filtri, an Italy-based filtration and contamination monitoring company, introduced the CML3 compact portable contamination monitor ahead of EIMA Bologna. The CML3 employs LED light-obscuration optics with photodiode detection to provide full 8-channel measurement of particulate and water contamination; it can store up to 4,000 test results and integrates with MP Filtri’s CMP View software for trend analysis. Additional features include a bright 7-inch touchscreen, durable battery-powered portability weighing 8.5 kg for sunlight visibility, rapid ISO/NAS/GOST standard reporting, and compatibility with hydraulic fluids, synthetic oils, and diesel. Typical use cases include field fleet inspections, maintenance of construction and plant-hire equipment, and mobile service operations requiring quick pass-or-fail diagnostics. The benefits include earlier identification of contamination issues, longer equipment lifespan, reduced maintenance costs, easier compliance with cleanliness standards, and minimized downtime through immediate, data-driven maintenance decisions.

In February 2024, BGE Indoor Air Quality Solutions, a Canada-based indoor air quality and air filtration company, acquired CON-TEST for an undisclosed sum. The acquisition is intended to broaden BGE’s market presence and technical capabilities in testing and certification services for controlled environments across Canada, strengthening its capacity to provide high-quality indoor air solutions in critical environments such as laboratories and hospitals. CON-TEST is a leading Canadian provider of controlled environment services.
