Yes, the Atoms Mask is washable. After 50 washes, the inner copper layer loses its effectiveness in its ability to actively destroy germs and particles. It can still be used as a regular cloth mask, but will not have extra antimicrobial benefits. To wash your mask, Atoms recommends placing the mask in a bowl or basin, adding a small amount of your favorite soap or detergent and water, and then using your fingers to work suds throughout the mask. After this is done, the mask should be rinsed thoroughly, pat or wrung dry of excess water, and then hung up to air dry.
The Atoms Mask is made of two layers - a polyester blend outer layer, and a copper-lined ionized quartz yarn inner layer which actively destroys all germs and particles that happen to fall on the mask.
Yes, the Atoms Mask is safe. Due to the mask's inner layer which is made of copper-lined ionized quartz yarn, all germs and particles that fall on the mask will be destroyed within four hours.

This active layer of defense makes the mask more than ideal for any person that is looking for a little extra protection while out and about. The Atoms Mask received the following awards:
