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; and one or more ultraviolet (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, 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: if only one UV lamp is present, the UV lamp is positioned relative to the interior surface so that its NIR region fills substantially all the interior space of the housing, and if more than one UV lamp is present, the NIR regions of adjacent UV lamps overlap each other by an amount which at its maximum is of between 5% and 25% of the radius of the NIR region. |
