How quickly does PURETi work?

Activation occurs immediately after the source of UV light is turned on; however, it takes a while for all the hydrocarbons, VOC’s, NOx and SOx in a room or in the air outside a building or solar panel to come in contact with the TiO2 crystals.

Effective residence time can be speeded up by pulling more of the polluted air per unit of time in close proximity to PURETi, where it can be destroyed. Deactivation occurs within minutes after the source of UV light is removed.
