Evidence for decontamination of single-use filtering facepiece respirators	2020-05-27		.txt	text/plain	4833	226	37	Physical and chemical methods of decontamination have been tested for treatment of FFRs with ultraviolet germicidal irradiation, sterilization by steam, ethylene oxide and vaporous hydrogen peroxide, demonstrating the most promising results thus far. Decontamination of masks to facilitate safe re-use has been postulated as one, albeit controversial 8 , solution with a number of studies over the last 20 years investigating the effectiveness of different decontamination methods on the performance of the treated FFR in protecting the HCW and/or removing the potential of the FFR to act as a fomite [9] [10] [11] [12] [13] [14] [15] [16] [17] [18] [19] . Filter performance does not appear to be significantly impacted either with autoclave, oven and microwave-based methods demonstrated to have no significant effect on FFR particle filtration 10, 15, 17 , including after several cycles of exposure to steam decontamination 12 .
