2 Smart VoiceON Face Mask AP551AWFA Wearable True HEPA Air Purifier WHITE. 2 filtration efficiency for 0.3m particles is higher than 99.97% Gen. 1 efficiency 2.5 m particles.PLEASE ADD A NOTE in CHECK OUT IF NEED BLACK MASK not WHITE. It is important to note that the only way to ensure 100% efficiency of blocking particle. Flow is to also block airflow. T airflow, you will not receive. From NASA have tested the particle capturing efficiency. Of filters and found that 0.3. Microns is the lowest point. Particles under 0.3 microns have so little mass the actually bounce around like pinballs when they. Hit gas molecules, so they move in random zigzag patterns. In fact, smaller particles, like 0.01. It seems counterintuitive that 0.3 micron. Particles would be harder to capture than 0.01 microns.
That is because we think of filters. That if a particle is smaller than the.
S in the net, it gets through. That is how HEPA filters.
Or N95 masks work for particles >0.3 microns. Fit through, either because they are. Than the filter hole size, or their inertia causes.Them to hit the filter fibers.
