Camfil Revamps flagship Hi-Flo Filter
Camfil has revamped its flagship Hi-Flo filter range with a 12% improvement in energy performance. This improvement has been taken as an average across multiple sizes in the range, compared to its predecessor.
The clean air solutions company first launched the Hi-Flo filter to target industrial and commercial applications in the late 1960s, with numerous updates since. The most recent update has been spurred on by the updated standard from the European Committee for Standardization (CEN). CEN’s standard “EN 16798-3” covers energy standards for ventilation solutions in non-residential buildings. The standard was updated in June 2025.
Camfil’s updated range has a new name and launches as the Hi-Flo ePM1 70% air filter and meets or exceeds filtration performance for targeted sectors such as hospitals, pharmaceuticals and other commercial buildings.
PowerChina Wins $4 Billion Contract for Iraqi Desalination Plant
PowerChina has won a contract worth around $4 billion to build Iraq’s first large-scale seawater desalination plant in the southern city of Basra, in partnership with an Iraqi company, officials said on Thursday.
Iraqi Prime Minister Mohammed Shia al-Sudani inaugurated the project, which will have a daily capacity of 1 million cubic meters and is expected to begin commercial operations in June 2028. The plant is part of government efforts to address severe water shortages in the southern region.
The project also includes the construction of a 300-megawatt power plant to supply electricity to the desalination facility, according to two Iraqi officials.
Efficient Air Filter Inspired by Mucus-Covered Nasal Hair
Researchers at South Korea’s Chung-Ang University have developed a filter that mimics the effects of the mucus layer coating nasal hairs, and it captures particulate matter effectively. Filters using this technology perform better than conventional air filters, owing to a mechanism called capillary adhesion, and have a longer lifespan.
In a study published in Nature, a research team led by Associate Professor Sanghyuk Wooh developed an effective bioinspired solution, dubbed the particle-removing oil-coated (PRO) filter, and the proposed air filtration system mimics the way mucus-coated nasal hairs trap particles.
The team created a stable thin liquid layer on filter media, by engineered filter fibers by grafting tiny polymer brushes onto their surfaces, then sprayed them with a non-volatile oil chemically similar to the brushes. This chemical match helps the oil spread evenly, forming a uniform film that adheres tightly. Unlike previous liquid-coated filters, this design prevents pore clogging, so air flows freely.
Extensive experiments showed that the PRO filter dramatically improves particle capture. It achieved a 10–30% increase in filtration efficiency across various particle sizes – from fine dust to large pollen – without significantly increasing the pressure required to push air through. This is due to the strong capillary forces provided by the thin oil layer, which enhance particle adhesion by orders of magnitudes.

Asahi Kasei’s Microza Membrane Division Receives EcoVadis Gold Rating
Japanese technology company Asahi Kasei announced that its Microza & Water Processing Division, which provides Microza® hollow-fiber membranes for filtration and separation, received a Gold rating in the EcoVadis sustainability assessment conducted in June 2025. EcoVadis is a sustainability assessment company based in France that performs the review annually. This rating places the Asahi Kasei division among the top 5% of all entities assessed.
Microza® is used broadly in two areas: water treatment processes, such as water purification and wastewater/industrial water reuse; and industrial processes, including filtration and separation in biopharmaceuticals, pharmaceutical water, food, and industrial chemicals. By providing membrane technology for these applications, Asahi Kasei contributes to improved productivity, reduced environmental impact, and effective utilization of limited water resources.
The EcoVadis assessment evaluates corporate sustainability initiatives across four categories: Environment, Labor & Human Rights, Ethics, and Sustainable Procurement. This assessment targeted manufacturing at the Microza® Fuji Plant and related supply and value chain activities. The Microza & Water Processing Division received particularly high marks in the Environment category.
EcoVadis ratings are based on international sustainability standards and have been awarded to over 150,000 companies across 185 countries and 250 industries. The EcoVadis evaluation has become a globally recognized benchmark for objectively assessing corporate sustainability efforts.
Hengst Filtration Acquires Chinese Air Filtration Specialist CSC Tech
Germany based company Hengst Filtration has taken a further step in its transformation from automotive supplier to filtration specialist in new areas. The company has signed an agreement to acquire the Chinese air filtration specialist CSC Tech, making it a full-service provider for the semiconductor industry.
CSC Tech manufactures fan filter units (filter-fan units) as well as HEPA and ULPA filters for the clean room production of Chinese and Taiwanese microchip manufacturers and electronics production. This ideally complements Hengst’s expertise in the field of particle and harmful gas filtration as well as trace gas filtration at artemis control AG. In future, the Hengst Group will therefore offer a full range of products for cleanroom and semiconductor production.
Like Hengst China, CSC Tech is based in the Yangtze River Delta (Shanghai, Jiangsu, Zhejiang and Anhui): Administration and sales are in Suzhou, a city with a population of 13 million, while production is located in Kunshan, which is part of Suzhou. Hengst also has its two Chinese locations in Kunshan and further north in Jinan (Shandong province).
Veolia Appoints New CEO for its Mobile Water & Integrated Services
Veolia has appointed Nicole Springer as CEO of Mobile Water and Integrated Services for its water technologies activities.
In this role, Springer will lead the global business line dedicated to services and mobile units, accelerating the deployment of Veolia’s large mobile fleet and expanding its emergency response capabilities, helping clients ensure business continuity while meeting increasingly stringent environmental requirements.
Springer comes to Veolia from Xylem, where she most recently led the utility services division in North America. During her six-year tenure, she also served as general counsel in Singapore before successfully transitioning to general management in Budapest, Hungary.
Filter King Opens New Manufacturing in Pennsylvania
Filter King LLC, the nation’s leading manufacturer of UL-certified custom HVAC filters, announced the grand opening of a state-of-the-art manufacturing and distribution center in Bethlehem, Pennsylvania. The announcement comes hot off the heels of the February launch of its Las Vegas, Nevada plant, and last year’s opening of its Miami, Florida headquarters and production facility. The 61,600 square-foot Bethlehem facility, equipped for production, warehousing, and distribution, significantly enhances Filter King’s ability to serve the Northeast’s growing demand for premium air filtration solutions.
“Our goal is to reach the entire continental U.S. with next-day delivery. With the addition of the Pennsylvania facility, which means we now have a total of 200,000 square feet of operational space across three states and a workforce of more than 125 employees, we are well on our way to achieving this goal,” said Rick Hoskins, Founder and CEO of Filter King.
Strategically located in the Lehigh Valley, the Bethlehem site was chosen for its proximity to major metropolitan areas, including Philadelphia and New York City, placing it within a seven-hour drive of 40% of the U.S. population. The facility’s access to robust transportation networks and a skilled local workforce supports Filter King’s rapid expansion and commitment to operational excellence, and commitment to American manufacturing.
