“…Among them, Sakano, Otani, Namiki, and Emi (2000) describe the influence of fiber size distribution on the collection performance of the filter for a mass median aerodynamic diameter of fiber of 1.8 m. However, experimental work on woven fabrics for air filtration is scarce. Indeed, the literature mostly deals with comparisons between the filtration efficiencies of different woven fabrics made of polyester/wool for sub-micronic particles (Sanchez, Rodriguez, Alvaro, & Estevez, 1997;Maini, Hersh, & Tucker, 1994).…”

“…PM filtration is mostly characterised in terms of filtration efficiency, penetration pressure drop and quality factor [34]. These terms are expressed using equations (1) to (4), respectively [35,36] and can be determined using principle setup shown in Figure 2.…”

This review presents an overview of electrospun nanomembranes produced from various polymers to filter air pollutants. Air pollutants can be categorised as particulate matter and gaseous pollutants. Both differ from each other in terms of size and chemical composition. Hence, the filter characterisation techniques and capture mechanism also vary. Particulate matter can be effectively captured in nanomembranes, in relation to microfibres, due to its small fibre diameter, small pore size and high specific surface area. Recently, electrospun nanomembranes have been used to filter gaseous pollutants owing to their potential of active surface modification. Different additives which functionalised the nanofibre surface for gaseous pollutant adsorption are also highlighted in this review. The characteristic features of nanofibres influencing the filtration efficiency have been discussed. Furthermore, various research challenges and future trends of electrospun nanomembranes in air filtration have been discussed.

“…With this in mind, the authors [6,7] previously defined those variables generically called filtration indices: I F and F. Henceforth, we shall use I F only to refer to the filtration index and we shall rename the second of these indices, F, the ''economic filtration index''. Moreover, we deduce the expression that define I F using dimensional analysis, applying the P, or Buckingham theorem [13,14], as detailed below.…”

“…Thus, it is possible to obtain further criteria for the comparison of such fabrics in gas filtration operations. In this sense, the authors have previously proposed certain parameters -I F and F-that were generically termed ''filtration indices'' [6,7]. Here, these were deduced using dimensional analysis.…”

The characteristics and properties of fabrics used to make filters, as well as the operation conditions, affect filtration and filter cleaning performance. Accordingly, it is appropriate to group, as done here, such characteristics in dimensionless numbers in order to compare different fabrics used in the filtration of gases in a simple way.In this sense, the authors have previously proposed certain parameters generically termed filtration indices and here these were deduced using dimensional analysis. What we have named cleaning efficiency index is also considered to evaluate the efficiency of a cleaning system. These parameters, and others widely discussed in the literature, were applied to the experimental results obtained by the authors in the filtration of fly ash aerosols with different nonwoven fabrics. Additionally, certain experimental results of other authors are used. The results show that the filtration and cleaning indices may be useful for the comparison of fabrics required for specific applications.
