This Purosis review notes that the engineering backbone of this unit lies in its 7-stage filtration architecture, which integrates RO, UF, and UV sterilization. By incorporating a mineralizer and alkaline cartridge, the system attempts to restore the pH balance often lost during high-pressure reverse osmosis. The 15 Litres/Hour filtration speed is particularly impressive, allowing the 9 L tank to refill in under forty minutes. This rapid recovery time ensures that peak morning demand in a busy household is met without significant wait times. Compared to standard 10-12 L/H units, this model demonstrates superior throughput efficiency, making it technically robust for high-consumption environments. This throughput is vital for maintaining water quality without causing undue strain on the electrical components during long filtration cycles.
Handling source water up to 2000 PPM TDS requires a resilient booster pump and a high-rejection membrane, both of which are present here. The mechanical assembly is designed to withstand the osmotic pressure necessary for such heavy-duty desalination. While noise levels remain within standard residential limits, the build quality emphasizes internal component protection rather than just external casing. The inclusion of a copper filter adds a layer of traditional bio-protection, while the UF membrane acts as a physical barrier against suspended solids. This specific combination is essential for Indian municipal and groundwater supplies that often fluctuate in chemical composition. The internal layout minimizes vibration during the high-pressure RO phase, which is a common point of failure in less sophisticated designs.
Ultimately, this model represents a pragmatic investment for those prioritizing technical depth over brand heritage. With its 1 year warranty on electronic components, it offers essential protection for the most vulnerable parts of the system. It outperforms basic entry-level devices by offering both alkaline and copper enrichment within a single chassis. For users transitioning from gravity filters or basic UV systems, this is a strong upgrade that addresses modern contamination challenges. The balance of 9 L storage and rapid 15 L/H processing makes it a logically sound choice for long-term domestic use. It provides a clear pathway for consumers wanting a durable machine that handles heavy mineral loads without requiring frequent manual intervention.
