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.

Purifiers.

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.
