Filtech is the world's largest trade fair for filtration and separation – and thus the global center for a technology that is indispensable in almost all industrial processes. Whether air and water purification, pharmaceutical manufacturing, food processing, chemical engineering, or exhaust gas aftertreatment – filtration is the silent guarantor of quality, efficiency, and safety. Twice a year, with its main location in Cologne, the trade fair brings together more than 400 exhibitors from over 35 countries and around 15,000 trade visitors. Plant manufacturers, materials scientists, engineers, operators, developers, and research institutes meet at the Koelnmesse exhibition center for intensive exchange—practical, solution-oriented, and internationally networked.
Filtech focuses on solutions for mechanical, thermal, chemical, and physical separation processes. The products on display range from filter media and fabrics to membranes, screens, centrifuges, and absorbers to complete systems, control systems, and measurement sensors. Applications that combine several functions in one system—such as filtration and drying or separation and recovery of valuable raw materials—are particularly in demand. There is an increasing focus on reducing micro-pollutants, particles, emissions, and energy-intensive process steps – driven by stricter environmental regulations, raw material shortages, and rising energy costs. Filtration technology is no longer a niche topic, but a driver of innovation across industries such as medical technology, mobility, recycling, and energy supply. Anyone interested in other trade fairs in the region will find a comprehensive overview at Cologne Trade Fair.
The increasing automation of industrial processes is also changing filtration technology. At Filtech, manufacturers will showcase intelligent filter systems that automatically adapt to changing flow rates or particle loads. AI-supported monitoring tools enable predictive maintenance, thereby extending service life, reducing operating costs, and increasing process reliability. Modular system solutions are also becoming increasingly relevant: they allow individual adjustments with low investment – ideal for companies that need to respond flexibly to market changes or regulatory requirements.
The trade fair is accompanied by the internationally recognized Filtech conference, which offers over 200 scientific presentations each year. Leading minds from research and development meet here to report on new materials, mathematical modeling, pilot studies, and practical tests. The spectrum ranges from molecular separation processes and biotechnological filtration to large-scale emission reduction. The interdisciplinary nature of the conference is particularly appreciated: physicists discuss with environmental technologists, mechanical engineers with pharmacists – it is precisely this interdisciplinary dialogue that makes the conference a knowledge engine for the entire industry.
The focus on new materials is also forward-looking: nanofibers, graphene coatings, ceramic membranes, and biodegradable filter media offer new possibilities for ultra-fine separation, temperature or chemical resistance, and cycle integration. Many manufacturers are focusing on resource-saving solutions – whether through the reusability of filters, low-energy cleaning processes, or material substitution to reduce microplastics and pollutants.
One of Filtech's strengths lies in its wide range of applications. At the trade fair, visitors will find solutions for air purification in operating rooms as well as for wastewater treatment in the pulp industry. Filtration is a key process in food production, crude oil processing, mechanical engineering, semiconductor manufacturing, agriculture, aerospace – and Filtech brings all these areas together in a compact, international platform.
In addition to presenting technology, Filtech offers excellent opportunities for initiating business and searching for strategic partners. Personal conversations, technical discussions, workshops, and evening events promote exchange and cooperation. Start-ups, hidden champions, and global market leaders meet here on equal terms – supported by targeted matchmaking formats, themed tours, and a clearly structured hall plan.
With its central location, excellent transport links, and strong industrial and academic landscape, Cologne is the ideal location for Filtech. The trade fair strengthens the city's position as a hotspot for technological innovation, engineering, and international knowledge transfer – and offers exhibitors and visitors a professional and inspiring environment. Filtech is a meeting place for everyone working on clean, safe, and sustainable solutions to the challenges of our time. It highlights what is technically possible and provides inspiration on how these possibilities can be successfully implemented in everyday life and industry.
