How does the Stream filter system compare with an ultraviolet filter system?
Ultraviolet (UV) disinfection uses a UV light source, which is enclosed in a transparent protective sleeve. It is mounted so that water can pass through a flow chamber, and UV rays are admitted and absorbed into the stream. When ultraviolet energy is absorbed by the reproductive mechanisms of bacteria and viruses, the genetic material (DNA/RNA) is rearranged and they can no longer reproduce. This system has proven to be an unsafe and unreliable bacteria treatment as bacteria can hide behind sediments and particles. Furthermore UV is not a filtration process, while the process will kill or paralyze the bacteria, it will still remain in the drinking water. The lifetime of the UV lamp required for this filtering process can also be unpredictable and may require constant maintenance. Finally, as with the reverse osmosis filtration system, the UV filter system requires high maintenance cost and it also requires electricity to run again increasing their energy bills.
