Nanofiber Filter Technologies for Filtration of Submicron Aerosols and Nanoaerosols covers the nanoaerosols (less than 100 nanometers) to larger submicron aerosols due mostly to pollution, which are present in high number concentration in our surroundings. People are breathing these nanoaerosols daily without being aware of it. Airborne viruses from flu to coronaviruses are also nanoaerosols. During the COVID-19 pandemic, it took a long time for health authorities and the General Public to recognize the airborne transmission mode of the virus. This leads to inadequate protection and ineffective virus control strategies resulting in high infection and death rates. The book cites evidence and observations pointing to the airborne transmission mode of the coronavirus. It also discusses different filtration technologies using nanofibers to capture these aerosols for short-term filtration, where aerosols are trapped in the filter (depth filtration), and long-term filtration, where aerosols are trapped in the growing filter cake (cake filtration). This book provides a good understanding on how nanofibers, which is of size 1/1000 times that of a normal human hair, can effectively filter these tiny aerosols. NFT, organized in four sections – fundamentals, deep understanding, technologies, and application, covering comprehensively on the subject, is a valuable resource for undergraduates and graduates, engineers, researchers and practitioners in related industries. - Describes technologies with insight and use basic engineering principles to build-up technologies - Includes extensive clear and understandable figures and tables to enhance key concepts - Uses examples throughout to explain engineering principles and interdisciplinary concepts - The only book in the market focusing on nanofiber filter technologies for filtering submicron aerosols and nanoaerosols

Recent toxicological studies show that nanoparticles released in technological processes and combustion processes outside industry can be dangerous for humans especially when entering the body through the mouth and nose. In connection with the above, the use of adequately effective respiratory protection equipment is of great importance in prophylactic and preventive activities. The first part of Nanoaerosols, Air Filtering and Respiratory Protection: Science and Practice refers to the general phenomena of filtration described on the basis of the authors’ own experience and international reports. The book also includes a description of the respiratory system and principles of its functioning and the accumulation of aerosol particles. It goes on to discuss technological innovations regarding the production of filtering materials for protection against nanoparticles and the latest test methods. Finally, the book contains information about the proper selection and use of respiratory protective devices against airborne nanoparticles in the workplace and everyday life. Special attention is paid to proper fit procedures as well as use and maintenance activities of such devices. The content of the book with rich illustrative material has been presented so that it can be used by health and safety experts, students as well as employers, employees and private users of respiratory protective devices. "Through a comprehensive approach to the subject of the work, the authors present theoretical foundations as well as practical solutions that are used in the research and development of personal respiratory protection. The complementarity of the information contained in the book will allow the reader to become familiar with a wide range of knowledge related to the design and manufacture as well as assessment of properties and procedures for the use of respiratory protection against the adverse effects of aerosols, including air contaminated with nanoparticles and microparticles. In my opinion the book is a valuable part of the series Occupational Safety, Health, and Ergonomics: Theory and Practice, published by Taylor & Francis." —Maciej Boguń, ŁUKASIEWICZ – The Textile Research Institute, Łódź

Filtration of aerosols is omnipresent in our daily lives, in areas as diverse as health, the protection of people and the environment, and air treatment inside buildings. However, the collection of particles within a filter media is not, contrary to popular belief, linked to a simple screen effect. The phenomena involved are much more complex and require the consideration of aerosol interactions, filter media and process conditions to select the best fiber filter for a given application. Aerosol Filtration, book for students, hygiene or process engineers, fibrous media manufacturers, designers, and filtration system suppliers or users addresses the filtration of aerosols in six chapters. These chapters cover physics and aerosol characterization, the fibrous media, and efficiency and filter clogging by solid or liquid aerosols, with special attention to the filtration of the nanoparticles. - Analyses the behavior of fibrous media against solid and liquid aerosols - Presents models of efficiency and pressure drop - Introduces computing elements for estimating the lifetime of filters - Provides guidance for designing filters and predicting their behavior over time

Any strategy to cope with an influenza pandemic must be based on the knowledge and tools that are available at the time an epidemic may occur. In the near term, when we lack an adequate supply of vaccine and antiviral medication, strategies that rely on social distancing and physical barriers will be relatively more prominent as means to prevent spread of disease. The use of respirators and facemasks is one key part of a larger strategy to establish barriers and increase distance between infected and uninfected individuals. Respirators and facemasks may have a role in both clinical care and community settings. Reusability of Facemasks During an Influenza Pandemic: Facing the Flu answers a specific question about the role of respirators and facemasks to reduce the spread of flu: Can respirators and facemasks that are designed to be disposable be reused safely and effectively? The committee-assisted by outstanding staff-worked intensively to review the pertinent literature; consult with manufacturers, researchers, and medical specialists; and apply their expert judgment. This report offers findings and recommendations based on the evidence, pointing to actions that are appropriate now and to lines of research that can better inform future decisions.

The need for clean air has probably never been greater. Many industrial employees need to avoid exposure to airborne particulates, while certain industrial processes demand clean air of exceptional quality. Medical and biological fields rely on sterile air, while filtration can improve air quality in offices, homes and all types of transport. Filters act in a variety of complex and subtle ways. Each chapter introduces its subject matter simply, before tackling the problem in greater depth. The book therefore provides an excellent basis for detailed study, but is also invaluable to anyone needing an overview of the subject.
