Abstract:
1. A hydroxyl generator comprising: a housing having an interior surface and an exterior surface, the interior surface defining an interior space having one or more apertures to permit entrance and exit of air into and out of the interior space, the housing having baffles for regulating how long it takes for air to pass through the housing; a blower or fan for moving air from outside the housing into the interior space and for ejecting air from the interior space, wherein the baffles cause the moving air to be present inside the housing for at least 340 milliseconds; and one or more UV-lamps arranged within the interior space, each of which, when generating UV-radiation, creates, in proximity to a surface of the UV-lamp, one or more near-infrared (NIR) regions having a radius, at least one of the UV-lamps generating UV-radiation with a wavelength of about 185 nm, wherein the NIR regions from the UV-lamps fill substantially all the interior space of the housing, whereby substantially all air entering the housing can only leave after having passed through at least one NIR region and is ejected from the interior space while containing hydroxyl radicals, with a positional arrangement of UV-lamps being as follows:
