The iteration of filtration technology for household water purifiers and the revolution of healthy drinking water

The upgrading of household water purifiers from primary filtration to intelligent purification is addressing the three major needs of water quality safety, taste optimization, and operational convenience.

Analysis of Defects in Traditional Filtering Technology

The combination filter of PP cotton and activated carbon can only remove large particle impurities and residual chlorine, with a removal rate of less than 30% for heavy metals, viruses, and antibiotics. Although reverse osmosis (RO) membranes can filter 99% of pollutants, they generate a large amount of wastewater (water production rate ≤ 50%) and cannot retain beneficial minerals.

Breakthrough application of new filtering materials

NMF nanofiltration membrane: Adopting a biomimetic water channel protein structure with a pore size of only 0.0001 microns, it maintains a 99% heavy metal removal rate while increasing water production to 75%. Laboratory data shows that its flux is 2.3 times that of traditional RO membranes.

Selective filtration technology: Through charge adsorption and molecular sieve effect, beneficial minerals such as calcium and magnesium are retained, while harmful substances such as lead and arsenic are removed. The mineral retention rate of a certain brand of water purifier is 82%, and the taste score is 40% higher than that of ordinary RO machines.

UV-LED sterilization module: using 275nm deep ultraviolet wavelength, the killing rate of Escherichia coli and Legionella is 99.99%, and there is no ozone residue. Compared with traditional mercury lamps, the lifespan is extended to 10000 hours and energy consumption is reduced by 80%.

Innovative Practice of Intelligent Monitoring System

Real time TDS display: Through conductivity sensors, the TDS value (total dissolved solids) of the effluent is dynamically displayed, allowing users to intuitively determine the lifespan of the filter element. When TDS exceeds 50ppm, the system automatically reminds to replace the filter element.

AI water quality prediction: Combining regional water quality data, user water consumption, and filter usage time, predict the remaining life of the filter. Actual testing shows that the prediction error is ≤ 3 days, which is 65% higher than the accuracy of the reminder when transmitting statistics.

Zero aging water technology: By flushing the front section of the RO membrane with pure water reflux, the problem of high TDS in the first cup of water is solved. Actual testing shows that after 12 hours of standby, the TDS value of the first cup of water decreased from 280ppm to 35ppm.
