I'd assume it would degrade N95 masks. Ozone reacts at least somewhat with both polyethylene and polypropylene at relatively low temperatures and short timeline

I'd assume it would degrade N95 masks. Ozone reacts at least somewhat with both polyethylene and polypropylene at relatively low temperatures and short timelines. This paper shows effects at 95F and 15-90 minute exposures: https://sci-hub.tw/10.1163/156856195X01012 https://sci-hub.tw/10.1163/156856195X01012
