Frequently Asked Questions

How long can I use a mask and how do I wash it?

Our mask can be hand washed up to 30 times before it loses its self-disinfecting properties. We recommend rinsing the mask once per week in warm water. Only use soap if absolutely necessary and avoid any laundry detergents, softeners, or bleach. They can destroy the special properties of the textile surface. 

How do I find the right size for my face?

Masks need to fit well to ensure comfort and protection. We offer sizes S, M, L for adults. To find the right size, please follow our size guide. We also offer a special Kids sized mask for kids age 6-10. All masks have adjustable ear loops and a bendable ultra-durable nose piece for optimal fit. 

Can I return the mask?

If you are not satisfied with our product, please write to so that we can issue a return label.
