This novelty of the CSIC’s improved masks has made them run out in a matter of days

Over time, new masks emerge that incorporate improvements or are more comfortable. These CSIC masks are being a success. We explain the reasons. Although most of us use hygienic masks, in risky work environments EPI masks of type FFP2 or similar are used, which not only protect others but also ourselves. That is, they protect in both directions. The Spanish Higher Center for Scientific Research (CSIC) has developed a new type of PPE masks that protect against covid-19. They have been sold out in just days, although they are not cheap. FFP2 masks filter the intake air, preventing the penetration of pathogens. But they are more uncomfortable to wear, because they use harder materials than hygienic masks, and you breathe worse with them. The novelty of these CSIC masks is the PROVEIL technology, which incorporate a filtering medium with nanofibers, developed by Bioinicia SL and the CSIC. What advantages does it bring? This special filter performs a mechanical filtering of airborne particles, instead of filtering by electrostatic charge, as most masks usually do. This mechanical filtering only lets through air molecules with a maximum size of 4 nanometers, as Business Insider explains. Since the coronavirus is a fairly large virus measuring between 80 and 150 nanometers, it cannot get through the fabric. So these CSIC masks prevent contagion, like the FFP2 masks. Another advantage of nanofibers is that the material is lighter, has 60 times less weight, without losing efficiency. Therefore they are more comfortable to use. And its durability is greater. They are not reusable or washable, but they last up to 48 hours, compared to 8 or 24 hours for most FFP2 masks. In two months they have gone from despising them, to being “highly recommended”. If you are going to wear a mask to go outside, this is what you should know. The product is certified under EU Exam Type No. 0370-4080-PPE / B for protection against COVID-19. It also meets the requirements of the UNE-EN 149: 2001 + A1: 2009 standard in relation to the evaluation of self-filtering half masks. In summary, they seem effective and more comfortable, although the specialist in R + D + I and food safety, Gemma del Caño, has clarified that at the level of use or effectiveness they do not have any difference with a normal FFP2. The CSIC masks are only on sale in some establishments such as OpenMarkt, but they are sold out. The pack of 10 masks costs 29.90 euros, and to that you have to add 10 euros of shipping costs.
