What do you mean by intensity of use?

We mean the duration of each individual use. Of course, this depends on the surface type and degree of exposure. In particular, objects and surfaces in environments that see frequent and continuous traffic require several disinfections during the day (always following the correct protocol for use), yet with different durations depending on what is being treated. For example, it will take longer to treat all the chairs inside a cinema or a theatre but less time to treat a handle, a garment or a single changing room in a clothing store. The appliances all come with instructions and protocols for proper use.
