What kind of filtration techniques exist?
There exist 4 different types of techniques to ‘filter’ or ‘clean’ the air: A. The mechanical filtration: professional technique used in e.g. clean rooms, laminar flow, etc (like MedicCleanAir® does) B. The electrostatic filtration: is based on creating electro magnetic fields to attract particles (only particles). Sometimes also equipped with a separate activated carbon filter as final-filter to adsorb gases. C. Ionisation: creation of negative ions to maintain an acceptable ratio between positive and negative ions. D. UV and disinfection: “killing micro-organisms through UV radiation or through spraying around specific insecticides / chemicals.
