Choose unique protection that not only captures viruses but also effectively deactivates them. The FFP2 RespiPro VK combines the benefits of a nanomembrane with patented accelerated copper technology. The result is a revolutionary self-sterilizing respirator with a typically copper color. It reliably protects you and your surroundings without the need for special care. Assuming you use the respirator for 5-6 hours a day, it will last up to 1 week. In other words, 30 hours cumulatively. For a better fit, use the plastic clip included in the package to fasten the straps behind your head. Extremely lightweight and comfortable. Available in sizes M and L. Weight: 3.7g. Made in the Czech Republic. The package contains 2 respirators.
