The masks manufactured by ARPE have been verified following the regulation UNE 0065: 2020 standard for hygienic masks. Whichdefines the requirements and test methods for the use of masks, and its purpose is to reduce the risk of spreading infections, particularly in epidemic or pandemic situations. According to these tests, our SKUT-0 masks have a bacterial filtration efficiency (BFE) of 92%, a differential pressure of 29 Pa / cm2 and have no resistance to splashes (Kpa).
This standard verifies the filtering capacity of masks from the inside to the outside. They protect from the inside to the outside to prevent the transmission of infectious agents to the environment from the person wearing the mask. But they are not personal protective equipment (PPE), they are not intended to protect from the outside to the inside.
The UNE EN 149: 2001 + A1 Standard specifies the minimum requirements to be met by filtering masks used as respiratory protection devices against particles and classifies them according to their performance and internal leakage to the inside in three classes; FFP1, FFP2 and FFP3 single use or reusable.
That is to say, there is no possible equivalence between one and another type of mask, because some are used to protect from inside to outside (UNE14683) and the others, from outside to inside (UNE149). Currently, the masks manufactured by ARPE model SKUT-0, we know that they have a high filtration capacity to the outside (92%) and we are awaiting the results of filtration from the outside to the inside.
The World Health Organization (WHO) recommends the use of surgical masks (according to UNE14683) to the general population, to reduce the spread of the pandemic, in the context of COVID-19. Although it also highlights that the use of a mask is not enough to provide a sufficient level of protection, so it also recommends strictly complying with hand hygiene and social distance measures. The WHO recommends that FFP2 masks are assigned to healthcare professionals.
