Il Filtro HEPA: Cos'è e come funziona - Filair - il purificatore d'aria con filtro brevettato

For large rooms up to 500 square feet, this air purifier features electronic controls and 4 fan speeds, including Turbo Setting to clear the air quickly, and Sleep Mode for quiet operation while saving energy. The True HEPA filter captures 99.97% of particles as small as 0.3 microns. A charcoal pre-filter traps odors and pre-cleans the air before it reaches the HEPA filter. Removes airborne allergens such as dust, pet dander, pollen, tobacco smoke, fabric fibers and mold spores!.
