We do not medical certification so we are not allowed to say that it does.
Not been tested.
These are assessments of whether the mask has the ability of Bacterial Filtration Efficiency (BFE), Virus Filtration Efficiency (VFE) and Particle Filtration Efficiency (PFE). The BFE and VFE tests are relatively low-level, and most medical masks with a water-repellent layer can pass. PFE is difficult, but PFE is also a lower-level test compared to CNS15980 anti-haze certification or N95 NIOSH inspection, because the air flux of PFE test is only 28 L / min, while CNS15980, CNS14755 or NIOSH are all used. The air flux of 85 L / min is nearly three times worse, so even if 99% of PFE is theoretically weaker than N95!
The nano protective layer in the BRISE mask, the water-repellent function comes from the layer-by-layer stacking of special water-based nanofibers. Since the filter material will be pulled during the washing process and may cause porosity lager, the anti-splashing ability may be slightly weakened with the number of cleaning times, but the hydrophobicity of the filter material itself does not change with the number of cleaning times. Can maintain a certain ability to prevent water splashing.
The recommended number of cleanings is 200. The average person cleans about every three days or once a week, so it can be used for about two years.
The recommended cleaning method is ‘gentle hand wash’. After all, the intensity of the washing machine differs for every person. In addition, you can add a general neutral detergent (cold detergent, hand wash, shower gel, etc.) to assist in cleaning. And you can hang it to dry, but do not tumble dry or iron it!
If you still want to use the washing machine, you must put it in a laundry bag for protection, and set the washing and dehydration mode to delicate washing, which will be safer. In addition, please be careful not to twist the wire on the upper edge of the mask excessively when wringing it, to avoid the wire breaking due to improper stress.
The 3M cloth masks are used to resist wind and sand and keep warm. “There is no” ability to filter PM2.5!
