The traditional surgical with ear loops is mostly for other pills. A properly fitting N95 seals all the way around the mask, and offers substantial protection for the wearer. The ones I wear have been found >99.9% efficient at filtering aerosolized COVID sized particles, which are quite a bit bigger than the 0.3um worst case test particle. Worse case because they actual filter with two mechanisms, one physical that works for large particles (think stuff getting caught in a fishing net) and another that’s electrostatic that works better for ultra fine stuff. 0.3 is the crossover where the combination is minimally effective.
