Performance and Key Features
11-Stage Filtration Process: The system uses a multi-step process: a sediment filter (Stage 1), two carbon filters for chemicals and odors (Stages 2-3), the RO membrane for removing dissolved solids and heavy metals (Stage 4), several alkaline filters to add minerals and balance pH (Stages 5-9), a UV sterilizer (Stage 10), and a final coconut shell polish (Stage 11).
Improved Water Quality: Users report a significant improvement in taste, describing the water as “incredibly pure and fresh” and “almost sweet”. The water is also safe for uses like filling baby bottles and making coffee.
Safety and Leak Prevention: The system includes an emergency leak stop detector that shuts off water flow upon detecting moisture, preventing potential water damage.
Installation, Maintenance, and Value
Installation Experience: Most users find installation straightforward with clear instructions and well-packaged components. Be prepared for a potentially time-consuming process and have a tube cutter and extra plumber’s tape on hand.
Ongoing Maintenance: To maintain peak performance, follow the recommended filter replacement schedule:
Pre-filters (Sediment & Carbon): Every 6-12 months
RO Membrane: Every 2-4 years
Alkaline & Post-Carbon Filters: Every 12 months
UV Lamp: Every 12 months
Overall Value: At a price point of around $260, this system offers excellent value with its comprehensive filtration, alkaline remineralization, and UV sterilization. Its durability and performance make it a worthwhile investment for clean household water.
The Express Water UV Alkaline RO System is an excellent choice for those seeking high-quality, purified water with the added benefits of alkalinity and UV sterilization.
This system is ideal for you if: Your primary concern is maximum water purity, you want the health benefits of alkaline minerals, and you have sufficient space and an electrical outlet under your sink.
You might want to reconsider if: Your under-sink space is very limited, you are not comfortable with a moderately complex installation, or your water quality is already good and you don’t require UV sterilization.
