The effect of ultraviolet C radiation against different N95 respirators inoculated with SARS-CoV-2.

ABSTRACT:

Objectives

There are currently no studies that have examined whether one dosage can be uniformly applied to different respirator types to effectively decontaminate SARS-CoV-2 on N95 filtering facepiece respirators (FFRs). Health care workers have been using this disinfection method during the pandemic. Our objective was to determine the effect of UVC on SARS-CoV-2 inoculated N95 respirators and whether this was respirator material/model type dependent.

Methods

Four different locations (facepiece and strap) on five different N95 FFR models (3M 1860, 8210, 8511, 9211; Moldex 1511) were inoculated with a 10 μL drop of SARS-CoV-2 viral stock (8 × 10⁷ TCID₅₀/mL). The outside-facing and wearer-facing surfaces of the respirators were each irradiated with a dos
