The SA900 is an air purifier designed for mothers and babies. With a powerful EBM suction fan and a H13 HEPA filter, it can rapidly reduce pollution in two minutes. The special coating on the filter inhibits the growth of bacteria and viruses and decomposes toxic formaldehyde into harmless water and carbon dioxide particles. The saturated filter will change color to indicate when it needs replacement. The SA900 features a smooth exterior with no sharp edges to protect users from injuries; it also features a panel with a 30º tilt display that is easy to read and operate. Three indicator light patterns below provide a visual representation of the current air quality.
