Tight-fitting FFP3 facemasks are ideal respiratory protective equipment during aerosol generating procedures in Covid-19 environment, and require a Fit Test (FT) to assess mask-face seal competency. Facial hair is considered to be an impediment for achieving a competent seal. We are describing an under-mask beard cover called Singh Thattha technique which obtained a pass rate of 25/27 (92.6%) by qualitative and 5/5 (100%) by quantitative FT in full-bearded individuals. Sturdier versions of FFP3 were more effective. Individuals for whom shaving is not possible, the Singh Thattha technique could offer an effective solution to safely don respirator masks.
Bearded individuals can use an under-mask beard cover ‘Singh Thattha’ for donning respirator masks in Covid-19 patient care
