MASKLAB Fashionable Adult Three-dimensional Mask-Walnut (10 pieces in a box)

MASKLAB It is the first brand of Hong Kong fashion protective masks, founded in 2020 during the new crown epidemic Through its professional printing technology, it has cooperated with Hong Kong and French designers to launch colorful and colorful printing patterns, making masks become the highlight of wearing and enhancing personal wearing taste KF Korean style three-dimensional mask - MASKLAB’s flagship product has better fit, airtightness, and protective effects than ordinary flat masks. The three-dimensional shape gives more breathing space between the face and the mask. It’s more comfortable to wear, and ladies don’t have to affect their makeup because the mask is contaminated with lipstick. What is the standard of masklab™ Korean three-dimensional mask (KF series)? - The masklab™ Korean three-dimensional mask has passed the SGS test to achieve the most stringent EU protective mask standard EN 149 certification. The high-velocity suspended particulate filtration rate is as high as 95%, and the air permeability remains Delta P 5.3 mmH2O / cm² The EU protective mask standard EN 149 is very strict (more stringent than the US N95), the filtration rate is 3 times the air flow test of the ASTM standard for flat surgical masks, and there is a tightness test, but the air permeability is not regulated, so general protection Although the mask-grade mask is very protective, it is very airtight! After research by masklab, we reduced the oily filtration rate (oil smoke, oil mist) that is less important to the virus to 85%, thus enhancing our air permeability to Delta P 5.3 (generally KF94 masks are above 9.0). Therefore, our total level It is FFP1, but has the virus protection function of FFP2 Many people may ask: 95% filtration rate of high-velocity suspended particles? Will it be less protective than Level 2 and Level 3 medical masks? The answer is absolutely no, but there is no less First, the air flow rate tested by EN 149 is 95 L/min, while the air flow rate tested by ASTM Level X is 28.3 L/min. Many surgical masks with more than 95% PFE are tested by EN 149, and the result is often less than 70%. The main reason is that the efficiency of the filter material is often affected by the air circulation. The greater the air circulation, the lower the efficiency of filtering particles. Second, EN 149 will conduct a tightness test to ensure that air leakage caused by the gap between the face and the mask will not exceed the standard, and the masklab KF series will reach within 15%. The standard for surgical masks does not test this, so many surgical masks have very high air leakage and are more suitable for protecting others rather than protecting themselves.
