Ultraviolet Light and UV Air Purifiers

 
UV Air Purifiers destroy viruses, bacteria, microbes, germs and mold spores. Mycotoxins are a byproduct of molds and can affect humans and animals. A typical air purification system first passes the air through other filters in the air purifier, the already filtered air is then circulated around the UV lamp, allowing for exposure time which in turn further purifies the air before it is released back into the room.

UV Air Purifiers can eliminate a whole range of airborne organic particulate, potentially harmful particles, making the air in your home or office refreshingly healthy.

When a material is forced to undergo a change or reacts due to exposure to light energy, the process is called photochemistry. When the light is in the ultraviolet spectral range, the process becomes useful for disinfection and purification purposes.

UV ( ultraviolet ) light, when strong enough, thus becomes an effective weapon for the destruction of organic or biological contaminants or airborne particulate. There is a wide range of these particulate, such as toxic volatile compounds, dust, dander, dust mite feces, and biological contaminants such as bacteria, viruses and fungi, in any untreated indoor environment and thus a potential source of discomfort or illness. The photochemical process can change these harmful organic substances as the molecular level, making them harmless.

Ultraviolet (UV) light has long been accepted by the medical community for it's purifying power, not only in the area of UV air purifiers but for purifying other substances as well, such as water.
