The core architecture of this Purosis unit utilizes a sophisticated RO+UV+UF+TDS+Mineral sequence. This 7-stage filtration setup is particularly noteworthy because it incorporates multiple membrane technologies to tackle both biological and chemical contaminants. The 17 L/hr filtration speed is significantly faster than entry-level 12 L/hr models, reducing the wait time during peak morning hours. By integrating a mineralizer, the system restores pH balance, which is a critical engineering choice for neutralizing acidity often found in high-TDS output. This technical configuration demonstrates a calculated approach to water recovery and purity levels.
Looking at the mechanical tolerances, the ability to handle up to 3000 ppm TDS is the primary differentiator for this system. This requires a high-pressure pump and a durable RO membrane capable of resisting heavy scale buildup. The 24 W power consumption indicates an optimized electrical circuit that drives the UV lamp and pump without excessive heat generation. Build quality reflects a focus on functional utility, housed in a standard food-grade plastic chassis. While it lacks high-end smart sensors, the manual TDS controller provides granular control over the final water taste profile.
The final verdict on this model depends on your local water source and mineralization levels. It represents a significant upgrade from basic units that lack mineral restoration or high TDS capacity. The 9 L tank is well-sized for typical Indian kitchens, providing an ample buffer for daily cooking. Given that electrical components are covered; dust and physical damage excluded, the investment is protected against common solenoid or motor failures. It outperforms basic entry-level devices in terms of raw filtration power and speed. For households dealing with hard water from deep borewells, this unit offers the necessary mechanical strength.
