asecos PURIFIAIR.620

To use air purifiers to remove fine dusts and particulates from the atmosphere, the correct filter must be used for the type and size of particles in question. How do fine dusts and particulates differ, and what kinds of filters can be used to clean dirty indoor air? This information will help you find answers to these questions. If you have further technical questions on basic filter technology, our experts will be happy to help. Contact us at or +49 6051 9220-0. Airborne particles come in different sizes: Basic filter technology principles Professional expertise 0,001 µm 0,01 µm 0,1 µm 1 µm 10 µm 100 µm 1 mm LARGE Filter efficiency Particle size SMALL Overall efficiency MPPS Most penetrating particle size Diffusion effect, electrostatic Minute particles (< 0.1 µm) are separated in the filter via natural electrostatic force. Inertia and screen effect: Particles are easily separated by the filters based on their inertia and size. i The most critical particles have a diameter of approx. 0.3 µm and are the most difficult to remove (technical term MPPS = Most Penetrating Particle Size). The MPPS serves as the basis for defining the efficiency of particle filters.
