Is the TVOC (ppm) reading the same as the Overall Index?

No, the TVOC (ppm) reading is not the same as the Overall index. The TVOC (ppm) reading is the “raw data” representing the concentration of VOCs in your air, while the Overall index is an index reading that combines both PM2.5 and TVOC (ppm) to give you a more comprehensive understanding of your air.
