The engineering behind this system centers on its 7-stage filtration architecture, which combines RO, UV, and UF technologies. The 0.8 L/min flow rate is achieved through a pressurized membrane system that minimizes wastage while maximizing throughput. This multi-layered approach ensures that dissolved solids are reduced while biological contaminants are neutralized. In a comparative context, this setup provides a more thorough barrier against microscopic impurities than standard single-stage filters. The integration of RO+UV+UF is particularly effective for households where the water source frequently changes between municipal supply and groundwater.
Mechanically, this model is built to handle heavy-duty input, supporting up to 2000 ppm TDS levels. This high threshold makes it suitable for regions with extremely hard water, preventing early membrane scaling. The internal 24 W motor operates with minimal vibration, though the noise levels remain within standard industry parameters for domestic RO units. The build quality utilizes food-grade plastics for the 9 L storage tank, ensuring stored water remains fresh. By maintaining a 7-stage process, the unit ensures each filter stage—from sediment to post-carbon—serves a specific structural purpose in improving taste and clarity.
Ultimately, the Au Soft unit represents a calculated investment for those needing reliable high-TDS treatment. The inclusion of a 1 Year Warranty on All Consumable and Electronic Parts is a rare and welcome addition in this category. It outperforms basic entry-level devices by offering both UV and UF stages alongside the primary RO membrane. For users transitioning from bottled water or basic dispensers, this represents a significant technical upgrade. Given the components included, it provides a stable and predictable performance profile for Indian households.
