It has an ergonomic design, the fabric itself makes a good seal around the chin area . 2) Advanced Filtration: Sealing is necessary but not sufficient to protect the user. Hawamask N95 Series provides 5 layered N95 filtration i.e. it ensures 95 % efficiency in capturing harmful particulate matters suspended in the air. It is rated N95 against PM 2.5 particles ( particles such as dust , smoke and aerosols that have a diameter of 2.5μm or less) 3) Comfortability: A wearer will rather choose to be exposed to pollutants, if the mask he/she wears is not comfortable no matter how much protection is at stake.
