We do not recommend the Automobile Dry-Mist Disinfection Machine for home use. The Automobile Disinfection Machine is designed for use in a small, confined space with good air circulation; ideal for a car. Proper room disinfection requires a machine with a higher volume of mist output and powerful circulation to ensure the mist travels through the entire area. Hence, using a small device such as the Automobile Disinfection Machine in a large room will not deliver the disinfection needed for healthy and germ-free air.
