What is ultraviolet?
Ultraviolet light is part of the light spectrum, which is
classified into three wavelength ranges:
- UV-C, from 100 nanometers (nm) to 280 nm
- UV-B, from 280 nm to 315 nm
- UV-A, from 315 nm to 400 nm. |

What is germicidal
ultraviolet?
UV-C light is germicidal - i.e., it deactivates the DNA of
bacteria, viruses and other pathogens and thus destroys
their ability to multiply and cause disease. Specifically,
UV-C light causes damage to the nucleic acid of
microorganisms by forming covalent bonds between certain
adjacent bases in the DNA. The formation of such bonds
prevent the DNA from being unzipped for replication, and
the organism is unable to reproduce. In fact, when the
organism tries to replicate, it dies. |
What are the beneficial
uses of germicidal uv?
Ultraviolet technology is a non-chemical approach to
disinfection. In this method of disinfection, nothing is
added which makes this process simple, inexpensive and
requires very low maintenance. Ultraviolet purifiers
utilize germicidal lamps that are designed and
calculated to produce a certain dosage of ultraviolet
(usually at least 16,000 microwatt seconds per square
centimeter but many units actually have a much higher
dosage.) The principle of design is based on a product of
time and intensity - you must have a certain amount of
both for a successful design. |

How do ultraviolet purifiers work?
Purifier units contain
one or more germicidal ultraviolet lamps. The Ster-L-Ray
 germicidal lamp
is a short
wave low pressure mercury vapor tubes that produces
ultraviolet wavelengths that are lethal to
micro-organisms. Approximately 95% of the ultraviolet
energy emitted is at the mercury resonance line of 254
nanometers. This wavelength is in the region of maximum
germicidal effectiveness and is highly lethal to virus,
bacteria and mold spores. Therefore, the water or air that
passes through the chamber is exposed to the germicidal uv
light and the genetic material of the micro-organism is
deactivated, which prevents them from reproducing and
renders them harmless. |
