UV Water Filter
UV Water Filter
A UV water purifier treats micro-biologically unsafe water with germicidal ultraviolet light. The UV wavelength scrambles the DNA of living organisms in the water, so they can no longer reproduce and make you sick. If you drink bacteria-infested water, the organisms can embed in your digestive tract and replicate. Ultraviolet radiation renders bacteria, viruses, parasites, and fungi unable to replicate by damaging the nucleic acids of their DNA.
A UV water purifier exposes living organisms, such as bacteria, viruses, or cysts (like Cryptosporidium and Giardia) to a germicidal ultraviolet wavelength. With enough energy, UV radiation at the 254-nm wavelength disrupts the DNA in pathogenic microorganisms so they cannot reproduce. The ultraviolet light prevents bacteria from spreading disease through drinking water.
UV dosage is the measurement of energy (in mJ/cm²) delivered by a UV water purifier. The more dosage provided, the more energy delivered to treat contaminated water. At a certain threshold, this energy becomes sufficient enough to inactivate most of the microorganisms present in water.
What does a UV disinfection remove?
UV disinfection deactivates living organisms, but it does not remove particles from water, add chemicals, or remove bad tastes and odors.
UV disinfection treats water for:
- Cryptosporidium
- Giardia
- Dysentery bacilli
- Salmonella
- Mycobacterium tuberculosis
- Streptococcus
- E. coli
- Hepatitis B
- Cholera
- Algae
- Fungi
- Some viruses
