Models typically have a 15-liter tank and up to 20 liters per hour purification rate.

Most models, such as the AQUA A+ or AQUA ROYAL, come with a 12-15 liter food-grade storage tank, sufficient for families of 4-6, with a purification capacity of 12-20 liters per hour depending on input water quality. High-recovery pumps ensure efficient operation even with low-pressure sources, and auto-flush mechanisms clean the RO membrane periodically to extend life. Power consumption is low at around 35-60 watts, with features like zero water waste technology in premium variants to minimize environmental impact.
