FAQ - Washable fabric masks (Last update: May 19, 2020 at 6:00 p.m.) General use Interview General Who is affected by the wearing of a fabric mask? The fabric mask is a mask intended for the public and in particular for any healthy or asymptomatic person. Its use does not in any way exempt the user from the systematic application of barrier gestures, which are essential, as well as from rules of social distancing aimed at combating viral infections. This device is not intended for use by caregivers in contact with patients. FFP2 type filter masks and surgical masks are intended to be used and reserved for healthcare personnel. Is there an equivalence of protection between fabric masks and FFP2 masks / surgical masks? No, these are different masks. An FFP mask is personal protective equipment (standard EN 149). It is intended to protect the wearer from both inhalation of droplets and airborne particles, which may contain infectious agents. Wearing this type of mask is more restrictive (thermal discomfort, respiratory resistance) than that of a surgical mask. There are three categories of FFP masks, depending on their effectiveness (estimated based on the effectiveness of the filter and face leakage). Thus, we distinguish: FFP1 masks filtering at least 80% of aerosols (total inward leakage <22%). FFP2 masks filtering at least 94% of aerosols (total interior leakage <8%). FFP3 masks filtering at least 99% of aerosols (total leakage inside <2%) A surgical mask is a medical device (standard EN 14683). It is intended to prevent the projection towards the surroundings of the droplets emitted by the person wearing the mask. It also protects the wearer against projections of droplets emitted by a person opposite. However, it does not protect against inhalation of very small airborne particles. There are three types of masks: Type I: bacterial filtration efficiency> 95%. Type II: bacterial filtration efficiency> 98%. Type IIR: bacterial filtration efficiency> 98% and resistant to splashes. People should adjust the cloth masks above the nose and under the chin and follow the same hygienic measures as for other masks. Does a cloth mask protect me from coronavirus? The masks do not protect you, but the people around you (if you are infected with the coronavirus, but you ignore it). Wearing a mask complements the existing measures which you must continue to scrupulously respect. use How many masks should we provide per day? We recommend using a cloth mask for a maximum of 4 hours. Each person who works outside his home can therefore plan 3 per day: 1 for the morning, 1 for the afternoon and 1 possibly for help. Remember to wash your hands or use hydroalcoholic gel before putting on a mask and after you take it off. How to use a fabric mask? Put on and take off your mask as little as possible. If you need to remove your mask for a short time (for drinking, for example), put it on a clean surface that you can easily clean up afterwards or store it in a breathable bag. Can I use a fabric mask in public space? You can completely use a fabric mask in public transport, in the supermarket or to circulate on the public highway Can I use a filter? On the back side of the fabric mask there is, on each side, 1 opening in which you can slide a replaceable filter. It is held in place by the inner layer of fabric. When should the filter be replaced? The filter should be replaced when it becomes wet. If you remove the cloth mask and put it back on later, also use a new filter. Interview How to wash a used fabric mask? We recommend washing a used fabric mask in a machine with conventional detergent, at 60 degrees for at least 30 minutes. Drying must be carried out either using a dryer or in the open air, before ironing with steam at a temperature which does not damage the fabric. Can I use an iron or steam iron to maintain my mask? Yes, to remove any creases after washing and finalize the drying. Particular care must be taken not to damage the components of the mask, in particular the elastic straps. Attention the passage of the iron cannot replace a washing as recommended. Can I use a hairdryer to maintain my mask? Yes, to remove any creases after washing and finalize the drying. Particular care must be taken not to damage the components of the mask, in particular the elastic straps. Attention the passage of the iron cannot replace a washing as recommended. Can I use a hairdryer to maintain my mask? A hair dryer is not suitable for cleaning. It can nevertheless be useful to finalize the drying of a fabric mask, but beware: poor control of the temperature level can degrade the mask. Do I have to disinfect my washing machine before washing cloth masks? This is an additional recommendation: washing beforehand is necessary if, during a previous cycle, you accidentally added a used mask with other clothes, when washing with a temperature below 60 ° C. If you wash all your masks according to the recommendations, you do not need to perform a vacuum wash beforehand. Can we wash cloth masks used with other clothes? Should we immediately wash masks immediately after use? Yes, you can for example wash your masks used at the same time with sheets or towels, which often accept washing at 60 ° C. It is important that the mechanical aspect of the wash is preserved. You can store the masks used in a specific container (clean and airtight container) and group the washes. However, beware of the risk of color transfer during the first washes! Can I immediately wear a new mask? It is recommended to wash a new mask before its first use. This allows you to make sure that the mask in question is healthy. Washing your mask before its first use also reduces the risk of allergies potentially caused by new fabrics. It should also be noted that the mask may shrink a few millimeters after the first wash.
