Unfortunately, the coronavirus crisis is likely to continue for several months.

So, as a means to help prevent further transmission, why not make your own mask? Its effective, reusable, and of course, eco-friendly! It’s even washable at 30ºC or more!

Together with the layers of cotton fabrics, the fleece inside guarantees extra security and comfort!

Objective: We would like to ensure that all people, whether working in the medical services or not, have access to basic personal protection.

We must point out that these instructions are for people who are not in direct contact with patients with coronavirus.


In order to be able to wash and change your mask regularly, we recommend you make several masks for you and others. If you leave your house, the mask should be washed in the washing machine on return to guarantee cleanliness and security.

Wearing a mask is not a licence to go out more often.

A mask’s effectiveness may vary, depending on its design and manufacture.

However, according to our medical colleague, wearing masks has certainly slowed down the spread in some countries. Masks prevent you from sneezing on others, thereby reducing the risk of transmission.  Masks also prevent you from touching your mouth and infecting yourself. We also remind you that being asymptomatic does not mean you are not a carrier of the virus.

A minimum of 6 feet (1,8 meter) for large droplets (containing large amount of virus), and 26 feet (8 meters) for small droplets (aerosols) is recommended to prevent virus spreading.
