“…The minimum collection efficiency, which is also referred to as the most penetrating particle size (MPPS), is obtained for the 100-300 nm size range. However, some studies showed that the MPPS for QFF may peak around 60 nm and are possibly < 100 nm for other fibrous media (Brochot et al, 2019;Zíková et al, 2015). While this measured values are mostly influenced by both the flow velocity in the sampling line and the pressure drop at the surface of the filter, our flow conditions are close to those used in the work of Zíková et al (2015).…”

“…99-166 nm modal diameter, Bescond et al, 2016). Filter collection efficiency is directly related to inertial impaction, direct interception, Brownian diffusion and electrostatic forces (Brochot et al, 2019;Lindsley, 2016;Zíková et al, 2015). The resulting component of these forces is translated into a function that displays near 100 % collection efficiency for particles smaller than 20 nm and larger than 300 nm.…”

“…These mechanisms are associated to the ‘mechanical’ filtration. The most penetrating particle size (MPPS) is then located around 300 nm ( Baron and Willeke, 2001 ; Brochot et al , 2019 ).…”

“…In addition, because particles less than 0.3 μm can be filtered due to the Brownian motion, the use of a HEPA filter is essential 48 . Nevertheless, an ultra‐low penetration air (ULPA) filter or a high‐rated MERV filter with a rating of MERV 17 or higher should be used to remove ultrafine and fine particles with a higher level of efficiency 49 . Lastly, if the temperature inside the chamber is high, the performance of the 3D printer may decrease.…”
