According to the United States Centers for Disease Control and Prevention (CDC), masks with valves or one-way vents do not help stop the spread of COVID-19. Some users have asked us if Totobobo masks use these vents.
We would like to clarify that Totobobo masks do not have vents or one-way valves (complying with the CDC recommendations). Rather, they are actually equipped with replaceable filters (F92, F94, F96, or PRO99) that provide high-efficiency two-way filtration of viruses, bacteria, and particles.
These filters are also designed to accommodate low resistance to air flow to help users breathe easily. The rest of the Totobobo mask contains a soft, transparent, silver plastic designed to resist viral and bacterial growth.
Together, this combination of functions built into the Totobobo mask and filters provides users with long-term comfortable wear and optimal safety for themselves and those around them.
