In order to deal with formaldehyde and total volatile organic compounds (TVOC) in the air, we will use specialized instruments to examine the amount of pollution and the type of pollutant, that enable us to propose suitable solutions. Inorganic carbon-containing gases such as carbon dioxide and carbon monoxide are excluded from this definition. Following the human perception, the German Federal Environmental Agency translates TVOC concentration (parts per billion) on a logarithmic scale into five indoor air quality levels (IAQ), as shown in Table below. When formaldehyde (HCHO) concentration is between 0.080 to 0.300 mg/m3or PM2.5 is between 55 to 250 mcg/m3,LCD screen displays Level as Unqualified in yellow, meaning air is in a borderlinecondition not qualifiedas Fresh but not meeting criteria for hazardous pollution.
