Triple Housing, 4-Stage Water Purifier from PURA
The AquaFlo / PURA UVB-3 Drinking Water System features Activated Carbon for removal of chlorine, taste, odors, chemicals, etc., and Ultraviolet Sterilization (UV) to remove waterborne bacteria, viruses, and other harmful microorganisms.
Your drinking water can be protected from E. Coli, Shigella dysenteriae, Salmonella, and other out breaks that occur from time to time in both municipal and well water supplies. The space-saving design of The Aqua Flo UVB-3 under-counter ultraviolet water purifier includes three stages of filtration for disinfected, bacteria-free water.
- Stage 1 - First, the water enters through a 5 micron string-wound sediment pre-filter to remove any sediment in the water.
- Stage 2 - Next, the water passes through a 5 micron activated granular carbon filter for removal of chemical contaminants.
- NOTE: Stages 3 & 4 are combined in the same housing.
- Stage 3 - As water moves to the 3rd housing, it flows down through a 0.5 micron carbon block cartridge removes heavy metals (i.e.; lead, mercury, copper) and cysts (i.e.; crypto, giardia cysts) as well as chlorine, taste, odors, and chemical impurities from the water.
- Stage 4 - The water then flows up through the center of the carbon block cartridge where the UV chamber is located. As water enters the stainless steel disinfecting chamber, it's exposed to high levels of ultraviolet light which attack harmful microorganisms, bacteria, viruses and sterilizes them. This process of purification works without chemicals and leaves no residual in the water supply. It is also more cost efficient than traditional methods of water disinfection, i.e. chlorinating, distilling or boiling.
This compact, under counter drinking water system installs with ease and can be used anywhere that clean, clear, good tasting disinfected water is needed. The UV lamp, sediment and carbon filters are easily accessible for years of maintenance-easy performance. It's ideal for point-of-use applications including under the kitchen sink, office water coolers, water vending machines, boats, recreational vehicles, etc.
How Effective is UV for Water Purification?
Ultraviolet (UV) light from the sun has long been known for its ability to destroy microorganisms. However, it has only been in recent years that equipment producing UV light has been manufactured for residential use. UV energy is produced by low-pressure mercury vapor enclosed in a tubular lamp. While a UV lamp resembles a standard fluorescent lamp, it is similar in appearance only. Energy produced by the UV lamp has the ability to destroy microorganisms that can live in water.
There are five major groups of microorganisms that are altered by a specific spectrum of ultraviolet light: viruses, bacteria, fungi, algae, and protozoa. When these microbes are exposed to the proper amount of UV energy, their DNA structure is scrambled, and they are unable to reproduce. Since the cell is now sterile or dead, it is no longer a threat.
