Key Points: 1. Clinical areas where Fibreoptic nasoendoscopy (FNE) and larygoscopy (FOL) are performed are high risk areas in the COVID-19 era as they are potential aerosol generating procedures (AGP). 2. Barrier protection remains the key to prevent transmission. This device is one that patients can wear to reduce potential aerosol contamination of the surroundings. 3. Seal can be verified and tested by the patient placing a thumb over the filter. 4. This device is simple, reproduceable, easy to use, economical and well tolerated. Full personal protection equipment (PPE) is still advisable to be worn by the operator. 5. This device may reduce potential aerosolisation and thus reduce the need to allow air changes in clinic rooms, freeing up clinical resources.
