FILTECH 2026, billed as the world’s largest filtration trade event, opened its doors at Koelnmesse on Tuesday, bringing together hundreds of exhibitors, researchers and industrial buyers for three days of exhibitions, technical sessions and networking focused on separation and filtration technology.
The show, running through July 2 at Koelnmesse’s Halls 7 and 8, has drawn 582 exhibitors from 36 countries, organizers said, with the exhibition floor fully booked ahead of the opening. The event combines a commercial trade fair with an international scientific conference, positioning itself as a single platform spanning business development, applied research and professional training for the global filtration sector.
Attendance at the previous edition, held in 2024, reached 18,760 participants, according to figures published by the organizers, underscoring the event’s scale within a niche but economically significant industrial segment. Filtration technology underpins a wide swath of manufacturing and environmental processes, from municipal water treatment to pharmaceutical production and semiconductor fabrication.
This year’s conference program features 160 oral presentations from researchers and industry specialists, with speakers given the option to publish accompanying papers with a digital object identifier, allowing findings to be cited and tracked within the broader scientific literature. The conference and accompanying short courses are ticketed separately from general exhibition entry, with conference and short-course registration starting at 440 euros and standard visitor tickets priced from 40 euros.
Organizers describe the exhibition as a business-to-business meeting point connecting suppliers and buyers from roughly 80 nations across more than 35 distinct end-markets. Sectors represented span water and wastewater treatment, air and dust filtration, pharmaceuticals, food and beverage processing, energy, desalination, mining, chemicals, semiconductors and battery manufacturing. Several markets have been added or expanded for the 2026 edition, including carbon capture, utilization and storage, cleanroom filtration, desalination, cement processing and leachate treatment, reflecting shifting industrial priorities toward decarbonization, water scarcity and advanced manufacturing.

Alongside the exhibition and conference, FILTECH is running three short courses this year covering solid-liquid separation processes, air cleaning and fine dust separation, and nonwoven materials, aimed at giving engineers and technical staff practical, applied instruction outside the formal conference track.
The event’s growth in scope mirrors broader momentum in the global filtration market, where demand has been propelled by tightening environmental regulation, expanding semiconductor and battery manufacturing capacity, and growing investment in water treatment infrastructure amid rising scarcity concerns in multiple regions. Industrial buyers attending the show are expected to be scouting suppliers for filtration media, separation equipment and system components as manufacturers look to meet stricter emissions and effluent standards.
Exhibition hours for the three-day run are set at 9 a.m. to 6 p.m. on Tuesday and Wednesday, with Thursday’s final session closing earlier at 5 p.m. The fair takes place at Koelnmesse’s North Entrance on Messeplatz 1 in central Cologne, a venue that regularly hosts large-scale industrial and trade exhibitions.
FILTECH has positioned itself over successive editions as a recurring fixture for the filtration and separation industry, alternating its scale and exhibitor base modestly between editions while maintaining its dual identity as both trade show and scientific congress. The format — combining live exhibitor business meetings with a peer-reviewed technical program — distinguishes it from purely commercial trade fairs and has helped it attract a cross-section of corporate buyers, equipment manufacturers, materials suppliers and academic researchers under one roof.
Organizers have already flagged the next edition, with FILTECH confirming dates for its 2026 instalment as part of a recurring cycle that has made Cologne a regular stop on the international filtration and separation industry’s calendar.
For exhibitors and visitors, the organizers list separate contact channels: exhibition inquiries are handled by Suzanne Abetz, while conference and visitor queries are routed through Sophie Grzanna, with a general phone line also listed for the Cologne-based organizing office.
