High Filtration Efficiency

Independently tested by the Particle Measurement and Technology Laboratory at the Missouri University of Science and Technology (USA), the LOG3Mask is a unique three-layer design with filtration efficiency, superior to surgical/medical masks for particle size 200 nm-5000 nm and reaches over 95% PFE for particles over 500 nm (Scientific studies showed that most coronavirus aerosols are in the size range of 250 nm to 5000 nm).
