Jade Pallett, microbiologist at ZOONO, says she sees the logic in double masking. ‘Given that the primary purpose of a mask is to act as a filter to particles in the air (including microbes), adding a secondary mask layer is likely to only add further protection – increasing the number of barriers in turn increases the level of protection,’ she explains. ‘It has also been noted that additional benefit may come from two masks ensuring that the gaps around a singular mask are covered.
