According to the United State’s Center for Disease Control and Prevention (CDC), masks with one-way vents or valves do not help to 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 one-way vents or valves (complying with the CDC’s recommendations). Rather, they are actually fitted with replaceable filters (F92, F94, F96, or PRO99) which provide two-way high efficiency filtration of viruses, bacteria, and particulate matter.
These filters are also engineered to accommodate a low airflow resistance to help users breathe easily in them. The remainder of the Totobobo mask contains a soft, transparent, and silver-embedded plastic designed to resist viral and bacterial growth.
Altogether, this combination of features built into the Totobobo mask and filters provides users with comfortable long-term use and optimal safety for themselves and those around them.
