La desinfection of surfaces by air (DSVA) is a method of disinfecting the surfaces of a room. It involves spraying a disinfectant into the atmosphere using a diffuser.
Advantages of the DSVA
The benefits of DSVA is the absence of human intervention, so it can be carried out at night to avoid immobilising a laboratory, a food factory, a train or even a classroom that must be operational during the day.
What's more, this method disinfects all surfaces in contact with the air. In fact, the DSVA, disinfection by air, is carried out in an airtight room and the product will spread throughout the volume until it saturates the room with a dry mist.
How can you be sure that the process is effective?
A standard, NF T 72-281, of airborne disinfection (DSVA)is used to certify the effectiveness of the diffuser/product combination. The standard makes it possible to determine bactericidal, yeasticidal, fungicidal and sporicidal activity.
Note that a diffuser/product combination may have obtained satisfactory results for bactericidal activity but not necessarily for the two remaining activities, fungicide and sporicide.
This French airborne disinfection must be issued by a COFRAC (French Accreditation Committee) accredited laboratory. Here is the test room of the COFRAC-accredited MRI laboratory for the NF T 72-281 standard obtained by IBL Specifik with its couple AIRBIO/APABIO for all activities (bactericide, fungicide and sporicide).
