Mann+Hummel installs Filter Cubes to purify the air in Ludwigsburg, Germany
Mann+Hummel’s Filter Cubes are being installed along Ludwigsburg’s Schlossstrasse in Germany to provide clean air in the heavily trafficked area. When the project is completed, a total of 15 columns will reduce the concentration of fine dust and nitrogen dioxide along the street. The Filter Cubes are distributed over a total length of 250 meters.
Mann+Hummel’s Filter Cubes draw in the polluted air and bind over 80 percent of the nitrogen dioxide (NO2) and particulate matter (PM10). The heart of this technology is a combination filter, which comprises a highly effective particle filtration layer and activated carbon layers that adsorb nitrogen dioxide. These activated carbon media adsorb NO2 very effectively due to their large surface area. The technology is characterized by a particularly low pressure drop. As a result, it effectively cleans the air with very little use of energy. Thanks to their modular design, the Filter Cubes can be assembled to form a filter column.
Currently Mann+Hummel’s Filter Cubes are cleaning 1.96 billion liters of air per hour worldwide, according to the company. In terms of per capita consumption, this means that the 403 Cubes now installed (in total: 140 columns), providing purified air for 4.1 million people.
“Many people think intensively about the one kilo of food and the three liters of liquids they consume every day. But we very rarely think about the quality of the approximately 12,000 liters of air that each of us breathes every day,” says Jan-Eric Raschke, director Air Solution Systems at Mann+Hummel.
“We all agree, it would be best if our air was so clean that it didn’t need to be cleaned at all,” said Raschke. “Unfortunately, it is not. Cities and metropolitan areas in particular face enormous challenges. At MANN+HUMMEL, we have made it our mission for eight decades to separate the useful from the harmful. Providing clean air with state-of-the-art filter technology is one of our main goals.”
In addition to various locations in Germany, Mann+Hummel Filter Cubes are also used in Brazil, China, India and South Korea, among other places. Further projects are currently being planned in Hong Kong, Mexico, Colombia, Singapore, Taiwan and Thailand.
The first systems were installed in December 2018 in Stuttgart, the capital of the German state of Baden-Württemberg. In 2020, a scientific report that examined the effectiveness of the installations along the street Am Neckartor concluded that, on average, a reduction of nine percent in nitrogen dioxide pollution was achieved, and in the area of the sidewalk and close to the buildings even a decrease of ten to 19 percent. The studies focusing on particulate matter PM10 showed an average reduction of more than ten percent.

DuPont, Waterise to collaborate on subsea desalination plants
DuPont announced that it has entered into a collaboration with Waterise to provide seawater reverse osmosis membranes and expertise to the company’s subsea desalination plants.
According to DuPont, subsea reverse osmosis (RO) desalination presents a sustainable and more economical way to turn seawater to freshwater. As subsea desalination leverages the natural hydrostatic pressure found at the depths of the sea to run the reverse osmosis, it reduces the energy requirements of conventional RO desalination by 40 percent. It also requires 80 percent less coastal land than land-based plants, presenting a viable option for communities with limited space. From an environmental perspective, subsea desalination requires lower amounts of pretreatment chemicals and eliminates the discharge of concentrated brine into coastal waters.
As Waterise’s patented desalination units reside on the sea floor, DuPont’s FilmTec seawater membranes were determined to be a good fit for this application.
“As we look to increase access to fresh water and enable a water optimized world, we are energized by opportunities to collaborate on innovative solutions to water purification, conservation and reuse,” said HP Nanda, global vice president and general manager, DuPont Water Solutions. “We are excited about Waterise’s new approach to desalination that not only reduces water scarcity, but also minimizes energy consumption and environmental impact.”

Camfil celebrates 10th anniversary of Tech Center; highlights capability of two new filter lines
Camfil is celebrating the 10th anniversary of its Tech Center in Trosa, south of Stockholm in Sweden. The Tech Center covers an area of 2,500 square meters with five laboratories – an HVAC particle lab, a HEPA lab, a molecular lab, an indoor air quality lab and a gas turbine lab – all fitted with the latest equipment.
The Trosa Tech Center is the hub of a global research and development organization, focused on working to analyze indoor air and to test the performance of different filters. The center opened in 2010, but Camfil built Europe’s first test rig for HEPA filters as early as 1967.
Anders Sundvik, vice president of R&D at Camfil, said: “As a business, we continue to invest heavily in research and development in order to innovate in the creation of sustainable products at the leading edge of technology. Clean air plays a massive part in many industries in terms of productivity and quality but, most importantly, it offers significant benefits for all humans’ health and wellbeing. The products that Camfil develops make an enormous contribution to this. The third perspective is environmental concerns by offering the lowest possible energy usage. However, Camfil refuses to rest on its laurels. Camfil has proven that it remains at the forefront of technology with the launch of two major filtration products – Megalam EnerGuard and Absolute V, the next generation HEPA filters for sensitive processes.”
Both new filter lines are designed to increase safety and productivity while also reducing energy consumption.
Megalam EnerGuard is a terminal HEPA/ULPA filter for cleanrooms with lower total cost compared to glass fiber and other competitive filters, through a longer service life, energy cost savings, operational efficiencies and manufacturing process integrity.
It contains a unique media that significantly decreases the chances of filter leaks and resultant room contamination in cleanrooms (first installations achieved 0% failure) to avoid the expensive costs of a product failure due to any mishandling.
Absolute V high airflow HEPA filters, meanwhile, are the energy-efficient filters that provide optimal protection with minimal total cost of ownership when installed in air handling units or in-line HEPA housings. With the Absolute V filter, Camfil placed a special focus on optimizing weight, robustness and energy consumption.

Polymer nanothread filter captures 99.9% of coronavirus aerosols in experiment
A filter made from polymer nanothreads captured 99.9% of coronavirus aerosols in an experiment.
“Our work is the first study to use coronavirus aerosols for evaluating filtration efficiency of facemasks and air filters,” said corresponding author Yun Shen, a UC Riverside assistant professor of chemical and environmental engineering. “Previous studies have used surrogates of saline solution, polystyrene beads, and bacteriophages — a group of viruses that infect bacteria.”
The study, led by engineers at UC Riverside and The George Washington University, compared the effectiveness of surgical and cotton masks, a neck gaiter, and electrospun nanofiber membranes at removing coronavirus aerosols to prevent airborne transmission. The cotton mask and neck gaiter only removed about 45%-73% of the aerosols. The surgical mask did much better, removing 98% of coronavirus aerosols. But the nanofiber filter removed almost all of the coronavirus aerosols.
Shen and George Washington University colleague Danmeng Shuai produced a nanofiber filter by sending a high electrical voltage through a drop of liquid polyvinylidene fluoride to spin threads about 300 nanometers in diameter — about 167 times thinner than a human hair. The process created pores only a couple of micrometers in diameter on the nanofiber’s surfaces, which helped them capture 99.9% of coronavirus aerosols.
The production technique, known as electrospinning, is cost effective and could be used to mass produce nanofiber filters for personal protective equipment and air filtration systems. Electrospinning also leaves the nanofibers with an electrostatic charge that enhances their ability to capture aerosols, and their high porosity makes it easier to breathe wearing electrospun nanofiber filters.

Indiana approves UV light air purification system for school buses
The Indiana State School Bus Committee approved the use of UV light air purification systems on Indiana school buses after a successful pilot program with Indiana-based Lumin-Air.
Andrew Desmarais, Chief Operating Officer of Lumin-Air said, “This approval is very exciting for Indiana school districts and puts Indiana on par with other states who have already approved these technologies to help provide clean air in their school buses. Most importantly Indiana schools can now implement a solution to help reduce the risk of transmission and better protect students, bus drivers and other school bus occupants against airborne respiratory pathogens like SARS-CoV-2 and Influenza.”
School buses are the most densely populated areas in a school’s facility and typically have the poorest air quality. Lumin-Air’s system includes MERV 13 filtration and UV lights in an enclosure, circulating clean, disinfected air throughout the bus. This is a much safer and healthier alternative to opening school bus windows, which can bring in unfiltered air containing exhaust, allergens, and particulates. The U.S. Environmental Protection Agency (EPA) urges limiting inhalation of diesel exhaust especially for children who still have developing pulmonary systems.
Timing for approval was critical as Indiana schools have until June 25th to turn in proposals for how they will allocate the large amount of Elementary and Secondary School Emergency Relief funds (ESSER) to improve air quality in their facilities and school bus fleets.
Lumin-Air has installed its solution in California, Pennsylvania, Florida and Maryland, on all major school bus manufacturer models and on two leading metro bus manufacturer’s vehicles. They also have a pilot program underway on a rail system.
