Electrostatic material & N95s have a unique property that it adds to the particle filtration especially in smaller particles.
Generally, we'll see non-electrostatic material to perform worse as the particles get smaller. (Right image)
But for electrostatic materials, it gets better at the smaller particles.
For the floor sweeper material, the charge is not strong enough to block the 1 or 2 um particles so we see less particles getting filtered.
The material is good at filtering at the larger 5 and 10 um particles.
I need to test these floor wipes with 4 layers and see how much more they filter since they will still be very breathable / equivalent to N95s.
