Aerosol transmission of pathogens can result in the rapid spread of disease. Introduction of a mobile air recirculation system based on high-efficiency particulate air filtration, photochemical oxidation, and germicidal ultraviolet light significantly decreased the bacterial load by over 40% under routine care in an emergency department. Application of this new technology promises to reduce the aerosol pathogen burden, thereby decreasing exposure risk and providing a safer environment for patient care.

Particulate matter (PM) and water pollution have posed serious hazards to human health. Nanofiber membranes (NFMs) have emerged as promising candidates for the elimination of PMs and the separation of oil-water mixtures. In this study, a polyvinylidene difluoride (PVDF)-based nanofiber membrane with an average diameter of approximately 150 nm was prepared via a double-nozzle electrospinning technology, demonstrating high-efficiency PM filtration and oil-water separation.

Emissions from more frequent and prolonged landscape fires (wildfires, risk reduction fires, agricultural burning) can expose populations to high levels of air pollution and exacerbate a range of health conditions. This systematic review aims to map, evaluate, and synthesise the scientific literature reporting interventions that can reduce exposure to landscape fire smoke (LFS). Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we searched PubMed, Scopus and Web of Science and reviewed relevant literature published until March 2024.

Air pollutants, particularly highly permeable particulate matter (PM), threaten public health and environmental sustainability due to extensive filter media consumption. Existing melt-blown nonwoven filters struggle with PM removal, energy consumption, and disposal burdens. Here, an ultralight composite filter with a vertical ternary spatial network (TSN) structure that saves ≈98% of raw material usage and reduces fabrication time by 99.

Invasive mould disease (IMD) has a high mortality in immunosuppressed patients. Invasive aspergillosis (IA) is the most common IMD. A guideline for preventing IA has been published jointly by the Centers for Disease Control and Prevention, the Infectious Disease Society of America, and the American Society of Blood and Marrow Transplantation.

Mitigation measures against infectious aerosols are desperately needed. We aimed to: 1) compare germicidal ultraviolet radiation (GUV) at 254 nm (254-GUV) and 222 nm (222-GUV) with portable high efficiency particulate air (HEPA) filters to inactivate/remove airborne bacteriophage ϕX174, 2) measure the effect of air mixing on the effectiveness of 254-GUV, and 3) determine the relative susceptibility of ϕX174, SARS-CoV-2, and Influenza A(H3N2) to GUV (254 nm, 222 nm). A nebulizer generated ϕX174 laden aerosols in an occupied clinical room (sealed-low flow).
