Our masks pass through a number of quality control checks to ensure and maintain the highest manufacturing standards before we ship them to your address. You may please find our test results by clicking this link.

Washing the mask before first use is not required. We recommend washing your mask only when necessary as excessive washing will affect the functionality of the filter.

Please follow our recommended washing guidelines to ensure that your mask is effective for your daily use. You can find it here.
