MVTEK Banale Mkcp Filtre à charbon actif, adulte, unisexe, noir

i bought the mask and the filters: i Have Asthma and going on the underground is a pain! since i started using this product, i come home with better feeling and no issues. the only thing you need to be aware of all types of good masks, when using them walk slowly as it reduced the amount of air you get in your lungs. it is catch 22, if the mask allows you to breath plenty then it is not filtering the air.

Its stylish and makes me look like Bane from Batman
