NEW OEM UNOPEN BOX * LG PuriCare H13 HEPA 2-FILTER compatible with 2nd Gen. LG PuriCare Wearable Air Purifier. Mask not included, separate processing;LG PuriCare VoiceON BLACK MASK Gen. 2 https://www.ebay.com/itm/174906202386 LG PuriCare VoiceON WHITE MASK Gen. 2 https://www.ebay.com/itm/174906162549 The filtration efficiency for 0.3m particles is higher than 99.97% (1st Gen efficiency, 2.5m particles). It is important to note that the only way to ensure 100% efficiency of blocking particle flow is to also block airflow. Without airflow, you will not receive oxygen, and you will suffocate and die. Scientists 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. HEPA filters are fantastic at capturing particles under 0.3 microns. In fact, smaller particles, like 0.01-micron particles are even easier to capture than 0.3 micron particles. It seems counterintuitive that 0.3 micron particles would be harder to capture than 0.01 microns (30 times smaller). That is because we think of filters like a net, thinking that if a particle is smaller than the holes in the net, it gets through. That is how HEPA filters or N95 masks work for particles >0.3 microns. These particles either cannot fit through, either because they are bigger than the filter hole size, or their inertia causes them to hit the filter fibers (impaction & interception). Bacteria are often about 1 micron, COV**19 has a diameter of approximately 60–140 nm or 0.06 to 1.4 microns. The H13 HEPA Gen.2 should be also compatible with LG PuriCare AP300AWFA (40/40/7mm), processing at your own risk. Be aware you will need to use 3rd speed (only) to blow more air on this restrictive H13 HEPA Gen.2.
