espiratory protective devices such as National Institute for Occupational Safety and Health (NIOSH) certified disposable filtering facepiece respirators (FFRs) are often recommended for use by healthcare workers and the general public for infection control. However, during a wide-scale breakout of a disease spread by human-to-human transmission via infectious aerosol, shortages of FFRs are likely. One possible solution to the potential shortage is to reuse the FFR after decontamination to…

Evaluation of Five Decontamination Methods for Filtering Facepiece Respirators
TLDR
Five decontamination methods were evaluated using nine models of NIOSH-certified respirators to determine which methods should be considered for future research studies and UVGI, ethylene oxide, and VHP were found to be the most promising decontaminated methods; however, concerns remain about the throughput capabilities for EtO and V HP.
Analysis of Residual Chemicals on Filtering Facepiece Respirators After Decontamination
TLDR
Measured amounts of decontaminants retained by the FFRs treated with chemical disinfectants were small enough that exposure to wearers will be below the permissible exposure limit (PEL).
Evaluation of Multiple (3-Cycle) Decontamination Processing for Filtering Facepiece Respirators
TLDR
Three-cycle 3X processing of eight different methods of decontamination of N95 filtering facepiece respirators finds that a single application of some methods did not adversely affect laboratory performance, but physical damage varied by treatment method.
Evaluation of filtering facepiece respirators using chemical decontamination methods
TLDR
Model 3 FFRs showed good performance where less deviation in the normalized filter aerosol penetration and normalized filter air flow resistance for the three decontamination methods was observed, and VHP is recommended to be used for decontamin methods for F FRs.
Decontamination Methods for Reuse of Filtering Facepiece Respirators.
TLDR
A protocol and best practice recommendations for redoffing decontaminated N95 and rotating N95 respirator use are described and UV light, steam, low-dry heat, and commercial sterilization methods with ethylene oxide or vaporized hydrogen peroxide appear to be viable options for successful decontamination.
A critical review of methods for decontaminating filtering facepiece respirators
TLDR
It is found that ultraviolet germicidal irradiation (UVGI) is the most widely studied method, and treatments are effective at inactivating SARS-CoV-2 without diminishing filtration efficiency or fit.
Effectiveness of three decontamination treatments against influenza virus applied to filtering facepiece respirators.
TLDR
These findings indicate that, when properly implemented, these methods effectively decontaminate H5N1 on the two FFR models tested and do not drastically affect their filtering function; however, other considerations may influence decisions to reuse FFRs.
Evaluation of Microwave Steam Bags for the Decontamination of Filtering Facepiece Respirators
TLDR
Evaluated steam bags marketed to the public for disinfecting infant feeding equipment were found to be 99.9% effective for inactivating MS2 on FFRs; however, more research is required to determine the effectiveness against respiratory pathogens.

TLDR
It is concluded that intermittent, low-level sodium chloride aerosol loading of N-95 respirators has a degrading effect on filter efficiency, but this reduction in filter efficiency was not accompanied by a significant increase in breathing resistance that would signal the user that the filter needs to be replaced.
Biodecontamination of animal rooms and heat-sensitive equipment with vaporized hydrogen peroxide.
TLDR
The VHP 1000 Biodecontamination System was easy to use and very effective in biodecontaminating animal rooms and equipment in a reproducible manner and work load and potential health risk for staff members and the environment was negligible.

TLDR
The issue of this potentially increased burden of the concurrent use of a surgical facemask with an N95 filtering facepiece Respirator is investigated to afford users the necessary information to make informed decisions Regarding the use of this Respiratory personal protective equipment in the face of large-scale outbreaks of Respiratories pathogens.

TLDR
In all six of the filter models tested, filter penetration values increased considerably and the most penetrating particle size noticeably shifted toward larger particles, indicating the need for additional research to define environmental conditions that may affect electrostatic filter efficiency.

TLDR
Generic descriptions of products or grouping of items were not sufficient to predict what is safe in terms of EO residual levels remaining on an item, and certain items exposed to EO sterilization must be further aerated prior to use, or discarded.
