The fan has a powerful suction: it takes air from a wide area from three directions. The Flash Streamer emits electrons at high speed, during which the electrons collide and combine with the air, and in the further process they break down dangerous substances. HEPA filter: successfully neutralizes impurities using electrostatic attraction; it rarely clogs / clogs, while a regular filter (which is not HEPA) catches particles in a fine mesh and is easily clogged by dirt, and the Streamer absorbs and decomposes unpleasant odors; it continuously renews its absorbency, so filter replacement is not necessary.
