Corona-COVID-19 MASK with Dual Exhaust Valves

The original design is ideal for continuous use that lasts just one hour, after which the mask becomes too hot to wear and precipitation begins to accumulate. Initially, our remix featured a single exhalation valve, but following extensive testing over several miles, we concluded that this would not be sufficient. Consequently, we opted for two exhalation valves, resulting in significantly improved comfort levels within the mask. Just prior to the pandemic's onset, we placed an order for Activated Carbon N99 PM2.5 Filters with Active Carbon N99 and Double valve exhalation. The valve assembly fits seamlessly into the mask, ensuring a snug fit. We also included a removable valve design option, allowing users to create their own valve if preferred.
