We strongly advise against the (long-term) use of mouth masks because of the adverse health effects of the wearer, and wearing them does not offer protection but a false sense of safety. If used carelessly, it can even be a larger source of contamination.
For detailed substantiated explanation, see SOURCE
If circumstances make it necessary to use the mouth masks, such as when traveling by public transport (mandatory as of 1 June in the Netherlands), it is of course best to use a mouth mask that is made from natural hypoallergenic materials such as hemp and organic cotton, which are completely free of chemicals. Hemp fibers are not only durable, but are also naturally anti-fungal and antibacterial.
The mouth masks below are especially suitable for people who consciously choose a sustainable material such as hemp, are chemically sensitive or allergic and / or are concerned about possible chemicals in the average masks made of plastic, vinyl or polyester. The mouth masks are washable and therefore reusable, and they are also produced fairly.
How to use?
Wash the mouth masks at 60 degrees before and immediately after use. Of course, use a completely natural soap, if desired with essential oils that are known for the positive effect on the respiratory tract and antibacterial and viral properties for support. The pure magic soap of Dr. Bronner, as with the scents TeaTrea, Eucalyptus and Peppermint.
WE POINT IT OUT AGAIN: OUR MOUTH CAPS ARE NOT SUITABLE FOR MEDICAL PURPOSES AND DO NOT PROTECT. THEREFORE THEY ARE SUITABLE FOR USE IN PUBLIC TRANSPORT AS REQUIRED BY THE DUTCH GOVERNMENT.
