COMBO: O2 Curve Mask v1.2 High Bridge + Black Shell + 5 Filters Details

The O2 Curve provides exceptional protection from airborne particles with a tight face seal and highly breathable filters. The O2 Curve provides premium respiratory protection without compromising on comfort or style. • Your nose bridge is near eye level • Your nose is raised/angled. • You can wear most glasses * Due to manufacturing limitations the microfiber pouch that is listed in the manual as coming with the O2 mask is not included. Notice: No respirator is capable of protecting you 100% against any other dangerous substance or virus.  In particular, COVID-19 is not yet fully understood.  We cannot and we expressly do not guarantee that our respirators will protect you against the Coronavirus. Due to the compact design of the O2 Curve mask, it is not compatible with the N95 testing procedure. The filter media used in the O2 Curve is capable of filtering ultra-fine particulates. Tests with this material have achieved greater than 99% efficiency down to 0.1 microns. In addition, the O2 Curve achieved a 98.6% efficiency for PM2.5 during tests performed at the University of Waterloo's Green Energy and Pollution Control Research Lab. No mask is capable of guaranteeing 100% protection against viruses. However, due to its medical-grade silicone seal, the O2 Curve provides a better air-tight seal and fit than most cloth and disposable masks. The VFE efficiency for the filter membrane used in the O2 Curve achieved a VFE of 99.997% in tests performed by Nelson Laborator
