Weinheim, Germany, September 9, 2025. Air filtration is everywhere – in cars, buildings, hospitals, industrial plants, and even our homes. But how does it actually work? What standards apply, and how are filters evolving to meet new challenges? Freudenberg Filtration Technologies answers these questions in “Filtration Unfiltered,” a recently published industry reference book, written by some of the company’s experts.

Whether seasoned professionals or newcomers to the field, readers of “Filtration Unfiltered” will find valuable knowledge presented in a clear, engaging, and accessible way. The 116-page publication in a compact format is richly illustrated and offers a comprehensive overview of key industry topics – providing technical insights into standards, technologies, applications, and future trends in air filtration.

At Freudenberg Filtration Technologies, we constantly improve and develop filtration technology to deliver innovative solutions for our customers in demanding markets. ‚Filtration Unfiltered‘ is a powerful testament to this dedication,” comments Dr. Alexander Rozmán, CEO of Freudenberg Filtration Technologies.

Technical insights into filtration technology, presented in an inspiring way

Filtration is essential across mobility, energy, healthcare, and household sectors, where Freudenberg Filtration Technologies has been a trusted partner for nearly 70 years. “Filtration often goes unnoticed,” says Christoph Staffa, Global Vice President of Marketing & Communication and book project manager. “Yet it is a key contributor to both public health and the performance of industrial processes – making it worth a closer look.”

The book’s carefully assembled chapters cover filter element design, international standards, testing procedures, and a wide variety of practical applications: from building ventilation and cleanroom technology to air purification in vehicles, turbomachinery, or household appliances. “As filtration experts, we strive to further develop the technologies we use and thus provide our customers with only the best support at all times,” says Dr. Thomas Caesar, Vice President of Global Filter Engineering Industrial and chief author of the book. “With ‚Filtration Unfiltered,‘ we wanted to offer both a technical foundation and an inspiring look into the capabilities of filtration.”

Looking ahead: filtration for the future

The expert book also looks forward, highlighting trends such as filtration solutions for fuel cell technology, advanced air pollution control, and smart, energy-efficient filter systems. Readers will gain insights into where the industry is headed – and how filtration continues to help protect people and the planet.

“Filtration Unfiltered” is published as a premium hardcover edition, initially available exclusively to customers and partners of Freudenberg Filtration Technologies.
