Portable household air purifiers are widely used devices designed to maintain a high-quality level of indoor air. Portable air purifiers equipped with the high-efficiency air (HEPA) filter served 100 h in a household space occupied by two adults without any symptoms of respiratory tract infection. The main objective of the study was to determine microbial contamination on the HEPA filter and to investigate if the selected nanotextile monolayer made of polyamide 6 (PA6) nanofibers can capture potential microorganisms when installed downstream of the HEPA filter as the final filtration medium. Samples were taken from the inlet and outlet surfaces. Samples from the nanotextile were collected in the same manner as from the HEPA filter. QIAStat DX® 1.0 Analyzer using the Respiratory SARS CoV-2 Panel multiplex PCR detection system was selected for microorganism detection. Adenovirus was detected on the inlet surface of the HEPA filter. The outlet surface of the filter contained no viruses included in the Respiratory SARS CoV-2 Panel portfolio. The nanotextile monolayer was replaced twice during the 100 h of operation, so three pieces were used and all contained coronavirus 229 E. Coronavirus 229 E was then detected in the nasopharynx of one of the members of the household as well. It may be assumed that the selected nanotextile is capable of capturing a virus of a small size.

“…Generally, the diameter of dust particles floating in the atmosphere ranges from 10 nm -10 µm, which were the main ingredients of air pollution. 1,48,2 A high-efficiency air filter could effectively remove bigger than 0.3 μm particles, but not smaller particles. For air purification, the filtration industry had been looking for a material to prepare a filter medium that could effectively filter particles below 0.3 μm.…”

The development of modern science and technology, improving the level of industrialization, increase people's awareness of environmental protection were leaded to the world's demand for filter materials to purify the air. This review presented an overview of air pollutants classification, history of fiber materials, theory of air filtration technology, and traditional air filtration (materials, characteristics, advantages, disadvantages, and standards). In addition, the paper reviewed the mechanisms of filtration, which include diffusion, interception, intermolecular interaction, straining, inertial impaction, gravitation, and electrostatic interaction of particles on the filter surface. Different studies have revealed the possibilities for the utilization of activated carbon fiber in the removal of VOC or odor from gaseous emissions in the air.

“…PM is classified by PM 0.1 as ultrafine (<0.1 μm), PM 2.5, fine (0.1–2.5 μm size), and PM 10, course (2.5–10 μm). 6,7 For particles between the micro and nano range (∼300 nm) electrospun nanofibres are proven to be more efficient that addresses two competing demands i.e. air filterability and air breathability.…”
