Yes, False Security, any mask or filter for that point is only as good as its rating if and when complete perimeter seal is achieved. Dust masks, no matter what they " N " rating are only as good as the perimeter seal.
Eta, get a 3M 7500 mask, fit it and then block the intake and inhale, mask sucks against your face like a dive mask. Combined with p100 filters, this can be ur masked Utopia unless u wanna block eyes too.
Soft mask N95 is great but please people know, your in and exhale always follow path of least resistance.
I.e . AROUND the perimeter, not through the filter. Its just physics.
