Deanshield Masks are one of the masks with the best breathability index, according to the certification of the Association for Research in the Textile Industry (Aitex).
According to the UNE 0065 technical specifications, the mandatory acceptance criteria for reusable hygienic masks must maintain the particle filtration efficiency above the 90% rate and the breathability rate below 60 pa/cm 2 . In the case of Deanshield masks, the breathability index is 23 pa/cm 2 maintaining protection above 95%.
This high rate of breathability makes them especially suitable for carrying out activities (professional or recreational) that require a certain physical effort or are carried out in spaces where the temperature is high.
