How do I charge the mask? 

Plug the included USB Type-C cable into the air turbine and connect the other end of the cable to a USB power supply(Not included). 

How long does it take to charge?

The led lights up red while charging. It turns green when charging is complete. Charge for 1-2 hours; this will give you approximately 3-4 hours of use in the first speed mode. * Charge time varies depending on the usage environment.

When should I replace the filter? 

The replacement time depends on the usage and actual environmental conditions. During a Jog or fitness workout, the respiratory rate increases and may cause excess sweating, so we recommend replacing it after such activities.
