The first layer comprises an electrostatic pre-filter medium that captures coarse particles. The second filter medium captures more dust; the third, with an active carbon layer, separates vapors, odors, and harmful gases like ozone, nitrogen oxide, and sulfur dioxide. Number four, the Meltblown medium, retains fine dust and microparticles with a diameter of less than 2.5 μm. The fifth bio-functional layer has an anti-microbial effect.
