The unit is designed to purify an area of around 60m² (or 300m³), provided that there is a good enough air circulation to allow the hydroxyl radicals to reach all areas of the room it has been installed in. 

However, Wellisair works by generating a chain effect to purify and amplify the total area being cleansed, increasing the total size of the area that it can purify. 

Wellisair devices are designed to be used in a maximum room size of 60m². If the space you are using has good air circulation and the full surface of the objects in question are in direct contact with the air, the unit can disinfect any object in 4 hours. 

For any objects which can't be kept in direct contact with the air on all sides (such as clothing), you would need to turn them over every 4 hours, meaning that disinfection would take 8 hours for these kinds of objects.  

Placing objects in a smaller space can reduce disinfection time by the same space-to-time proportions. For example, in a room of 25m², 2 hours would be sufficient time on each side, meaning that for any objects which require two-step purification, 4 hours would be sufficient. 

We have also developed some test strips which can be used to check whether the disinfection process has been carried out correctly. Therefore, for any cases where disinfection may take less time than normal, these strips can be used to check if disinfection is complete, which avoids you having to keep these objects in this room for longer than necessary.
