I waited for the installation to resume my work in all serenity (I am 63 years old)
My daughter had resumed before with the obligation to open the windows during 1/4 of hour between 2 appointments. Washing the floors etc..
The lamps allow us a complete air ground and surface disinfection in 4 minutes
The device (UVmastercare) is very easy to handle
Thank youJean Marc Bouaziz, France
