The shortage of N95 masks is driving the efforts to find ways to reprocess (sometimes referred to as decontaminate, sterilize, sanitize or disinfect) these filtering facepiece respirators (FFR). We continue to receive emails expressing concerns from health providers worried that ineffective reprocessing will leave them exposed to contamination or degraded respirators. This is an issue that is evolving, there is ongoing research, and we provide here an update.

In every COVID-19 update we profile an issue or respond to some those raised by you. Please continue writing!
