The three-day FILTECH 2026 International Exhibition for Filtration & Separation Technology in Cologne, Germany, has drawn to a successful close. As one of the world's most prestigious and influential professional events in the filtration industry, the exhibition brought together over 600 industry enterprises and more than 20,000 professional buyers globally, serving as a core exchange platform for cutting-edge filter media technologies and industrial separation solutions. COFON, the flagship filter media brand of Zhejiang Chaohui Filtration Technology Co., Ltd., returned to the showfloor once again, with a diverse lineup of self-developed filter media winning high recognition from clients worldwide. Our domestic and international sales teams remained on-site throughout the exhibition to engage visitors, conducting in-depth discussions with global clients and industry peers and securing widespread recognition as well as numerous cooperation intentions.
I. Industry Barometer: FILTECH, the World's Premier Filtration Summit
Founded in 1967 and hosted every 18 months in Cologne, Germany, FILTECH is a long-standing professional exhibition dedicated to filtration and separation technologies. It covers full-spectrum filtration applications including gas-solid separation, liquid purification, high-temperature dust removal, water treatment and clean production, alongside a series of specialized technical forums that facilitate cross-chain communication spanning filter media R&D, equipment manufacturing and end-user applications.
Aligned with industry trends centering on energy conservation, long-service filtration and compatibility with extreme operating conditions, the exhibition attracts technicians and procurement specialists from chemical, energy, pharmaceutical, environmental protection, semiconductor and other sectors. It also acts as a vital channel for COFON to tap into international markets, absorb pioneering technologies and showcase domestically developed filter media products.
II. Comprehensive Filter Media Portfolio Takes Center Stage: COFON's Seven Product Lines Win Global Buyers' Favor
At this year's exhibition, COFON presented its complete portfolio of mainstream filter media, consisting of glass fiber media, bag filter media, melt-blown media, PTFE media, composite materials, special filter papers and nanofiber filter media. These products cater to industrial dust removal, air purification, liquid filtration, precision equipment filtration and a wide array of other scenarios, fully addressing filtration demands across diverse industries.
UltrNanoflow nanofiber filter media, independently developed by our company, emerged as the star product of the exhibition.
It delivers distinct advantages over conventional glass fiber filter media:
Lower Resistance for Long-Term Electricity Savings
Under identical air velocity testing, the initial pressure drop is 30%–50% lower than that of traditional glass fiber media. Reduced fan load cuts energy consumption costs over long-term factory operation. Corresponding pressure drop comparison curves clearly demonstrate that the nanofiber media maintains lower operational resistance than glass fiber across all tested air velocities ranging from 2.5 cm/s to 5.3 cm/s.

Stable Filtration Efficiency with Powerful Ultra-Fine Dust Interception
Featuring a gradient layered fiber structure, the material consistently achieves filtration grades from E10 to H14, with optional U16 high-efficiency grade. It captures 99.95%–99.99995% of ultrafine particles measuring 0.12 μm. Conventional glass fiber media suffer obvious efficiency decline at high air velocities, while this nanofiber material maintains minimal efficiency fluctuation for consistent purification performance.

Higher Dust Holding Capacity for Extended Replacement Cycles
Laboratory tests confirm its dust holding capacity far exceeds standard glass fiber media. Resistance rises slowly as dust accumulates, eliminating frequent media replacements, reducing downtime for maintenance and cutting consumable replacement expenses.

Fiber-Shedding-Free & Contamination-Free for High-Standard Clean Environments
Manufactured via an all-synthetic process, the media generates no secondary contamination from glass fiber shedding. Free of boron, silicon and plasticizers, it features extremely low substance leaching for eco-friendly, clean performance - ideal for stringent dust-free production facilities such as semiconductor workshops.
Robust Compatibility with Operating Conditions & Easy Processing
It withstands high-humidity environments and resists deformation after pleating. Capable of enduring short-term temperatures up to 150°C, it supports custom sizing and can be fabricated into pleated filter media or finished V-box filters compatible with a wide range of filtration equipment.
Applicable Scenarios
• Industrial and commercial central air ventilation systems, ideal for equipment with limited installation space
• Final high-efficiency filters for clean workshops and primary pre-filters for air conditioning units
• Diverse commercial air purification devices and high-precision end filtration for special industrial exhaust gases
III. Over 200 Overseas Partners Received in 3 Days with Customized Filtration Solution Consultations
For this exhibition, Chaohui Group assembled a cross-border integrated sales team, with regional managers for Germany, France, the Middle East, Turkey and China stationed on-site to deliver seamless multilingual communication.
Across the three-day show, our booth welcomed more than 200 industry professionals hailing from Germany, France, the United Kingdom, Italy, Middle Eastern nations, Turkey, the United States, South Korea and other regions, including filter media traders, full-set filtration equipment manufacturers, industrial environmental engineering contractors, filter producers and laboratory R&D specialists.
During consultations, our team provided one-on-one customized filtration solutions tailored to each client's unique operational challenges. Many long-term international clients visited our booth to align annual procurement plans, while multiple leading European and American enterprises reached preliminary intentions for sample testing.
IV. A Milestone, Not a Finish Line: COFON Continues Deep Cultivation in the Global Filtration Industry
Following the conclusion of the Cologne exhibition, we have collected extensive practical operational demands from overseas clients. Drawing on Chaohui Group's long-term accumulation in material R&D, COFON will further optimize nanofibers, modified PTFE, specialty glass fibers and other product lines, focusing on low-energy, long-life filter media engineered for extreme working conditions.
Moving forward, we will keep expanding our presence in European, American, Middle Eastern and Asia-Pacific markets, adjusting our products to comply with local industry standards and supplying customizable, cost-stable filter media solutions to clients around the world.
