U-Mask Model 2.2
Regenerated nylon cover:
The outer part of U-Mask (the coloured cover), can be safely washed under water or in the washing machine at low temperatures. Afterwards, you can allow it to dry by hanging it. Do not tumble dry.
The inner part of U-Mask can be cleaned with a warm damp cloth or a wipe that doesn't use chemicals. Do not wash nor submerge under water.
Storage and further use:
Make sure that both the refill and the cover are completely dry before use. You can safely store your U-Mask in the original sachet it came in when not in use.
Remember that the U-Mask Refill lasts for up to 200 hours of use or for 1 year after it has been opened. This means that you can breathe into it for up to 200 hours within a year from opening the packaging. The cover can be used as much as you like, however if used a lot it may become less resistant and perhaps need to be replaced.
