In view of the shortage of masks that many people are facing everywhere, we have designed this model which may, perhaps, serve as a minimum against dr...oplet projections for those who have no protection. For the filter, and in the example, we have simply used filters made of lined paper (such as bamboo fibre coffee filters) because they are stiffer than absorbent paper. Other types of filters can be imagined, such as fabric... Once used for an outing, we recommend replacing the paper filter and cleaning the mask with soapy water.
Very important points to consider :
This mask is not a medical device,
This mask is not a certified protective device,
Its effectiveness has not been tested,
It does not protect against COVID-19/CORONAVIRUS,
Cannot be suitable for caregivers who need full, validated protection.
You should always favour the use of certified masks.
This mask should only be used as a last resort but without guarantee of protection.
Don't forget the recommendations.
Stay home, limit contact, wash your hands frequently, avoid touching your face (nose and mouth).
