High efficacy of activated carbon fabric filters and masks developed to prevent the inhalation of microorganisms and particles associated with respiratory tract infections
Abstract
<jats:p> As a major international public health emergency, COVID-19 has posed many challenges for healthcare professionals who have been heavily exposed to contamination. This article describes the development of a high-filtration capacity mask consisting of filter-element layers interspersed with super-activated carbon fiber fabric, non-woven polypropylene for dental–medical–hospital use and antiviral polyamide with nanostructured SiO<jats:sub>2</jats:sub> thin film coating. The study found 98.18% particle filtration efficiency and determined 2.11 mmH<jats:sub>2</jats:sub>O/cm<jats:sup>2</jats:sup> differential pressure, while fluid repellency complied with Brazilian standard NBR ABNT 15052:2004. </jats:p>
