Singapore’s two-layer cotton fabric reusable mask that claimed to offer 97+% antiviral and 99.75+% antibacterial protection after 30 washes—its last free distribution to the public, which lasted a fortnight, occured on Pi Day, 2021.
Compared to previous “inferior quality” reusable masks that were also given free to the public, MaskPlus needed to be washed only once a week even if worn daily—users could wear it every day for up to seven months.
