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.
