How often do I need to change the filter?

Great news! There's no need to change the filter, as the entire mask acts as the filter.

For the best possible seal, the filter is integrated directly into the mask. This design allows the mask to last an average of 3-6 months. Check our usage table below for detailed information on the lifespan of our masks
