The Protek Nano A99 3D Nanofiber N95 P2 Face Mask offers next generation particulate filter performance designed for commercial, industrial, and general consumer use. It’s enhanced, modern 3 panel design provides additional space around the mouth and nose for improved comfort during long term use. Manufactured in Perth, Western Australia to ISO 13485 Medical Device standards, our proprietary nanofiber filter face masks achieve N95 P2 Respirator standards with BFE and PFE >99%, Level 3 Delta P "breathability" and Level 3 Hydrophobic performance. The masks can be effectively worn for up to 24 hours before disposal - saving costs and reducing environmental waste - due to the superior performance delivered by our nanofiber filters compared to conventional masks with melt blown filters that need to be disposed of after 2 hours use. Protek Nano face masks are light weight, highly breathable, latex free and comfortable to wear over extended time periods. The masks have a quality feel unmatched by other products, and when properly fitted, reduce the frustration of "glass fogging".
