20 18, 1 1, General Administration of Quality Supervision, Inspection and Quarantine and National Standards Committee officially issued the national standard GB349 14-20 17 "Water Efficiency Limits and Water Efficiency Grades of Reverse Osmosis Water Purifier". In order to implement the strictest water resources management system, this standard is marked with the red line of strictly controlling water use efficiency, and will be implemented from 20 18 1 1.

After the implementation of the new national standard, all RO reverse osmosis water purifiers with net water output less than 35% are regarded as unqualified products. The new national standard will eliminate inferior products with high water consumption by setting water efficiency limits.
