And for how many times?	2020-04-07		.txt	text/plain	5343	272	56	We found that heating (<100 {degrees}C) under various humidities (up to 100% RH at 75 {degrees}C) and ultraviolet (UV) irradiation were the most promising candidates for mask reuse in the modern hospital infrastructure (up to 20 cycles), when tested on a fabric with particle filtration efficiency [≥]95%. For dangerous airborne particulates, including viral aerosols during the current COVID-19 pandemic, the United States Centers for Disease Control and Prevention (CDC) recommends the usage of N95 filtering facepiece respirators (FFR) as personal protective equipment for healthcare professionals [18] [19] [20] . We applied these treatments (see methods for details) to a meltblown fabric (20 g/m 2 ) that has an initial efficiency of ≥95%, which may be integrated into N95 FFRs. We evaluated the filtration efficiency and pressure drop of these treated fabrics via industry standard equipment, Automated Filter Tester 8130A (TSI), with a flow rate of 32 L/min.	./cache/cord-296227-dm1wkpnv.txt	./txt/cord-296227-dm1wkpnv.txt
