We do not recommend using the Classic 200 Disinfection Machine for the living room as it only covers small rooms up to 35sqm. The mist output of the Classic 200 will not be able to disinfect the entire area completely if it’s more than 35sqm. If you’re looking to disinfect larger communal areas such as the living room, a suggestion would be to use the Classic 250 Dry-Mist Disinfection Machine that covers up to 65sqm for disinfection.
