In general, higher filtration efficiency will cause higher breathing resistance. The filtration efficiency of a FFP3 respirator is up to 99% against solid and liquid aerosols where the breathing resistance is higher which might make the customers difficult to breathe. In order to solve this problem, some manufacturers have to enlarge the size of the respirator. Instead, we provide an unique "Big Eye" design for SH9360V FFP3 respirator. The "Big Eye" fold design can create larger effective filtration area which can lower the breathing resistance obviously. Wear it and feel it, you will be surprised why a FFP3 respirator can enjoy such low breathing resistance.
