  • Potassium is vital for the functioning of all living cells. It helps maintain a normal heartbeat and the blood’s pH level. It is also an important element in the synthesis of protein.
  • Sodium can stimulate nerves and muscles, regulating osmotic equilibrium and pH and promoting the absorption of nutrients such as glucose and amino acids.
  • Magnesium is one of the most abundant elements in the human body. It stabilizes muscle health and nerve function and helps maintain a normal heartbeat.

Fresh and pure enjoyment The filter works perfectly with any refrigerator, allowing you to enjoy icy and fresh water, which is deeply filtered and purified.
Can the system reduce TDS?
No. To come straight to the point, TDS value isn’t directly related to water quality.
TDS stands for total dissolved solids. The higher the TDS is, the more impurities water contains. But what are impurities on earth? No matter beneficial natural minerals or harmful substances, they are all regarded as impurities in water.
As a result, water quality can’t be determined only by TDS value. It is just one of standards that reflect water condition and you can’t conclude that water with low TDS is definitely of good quality.
TDS has more influence on water taste, not overall water quality.
Waterdrop under counter water filter reduces harmful pollutants while retains natural minerals, thus ensuring purity and good taste of water at the same time.
Can the product filter well water?
No. This system is designed for Municipal Tap Water. If using well water as the source, please make sure the feed water has been through a pre-filtration system, otherwise, large particles in well water will clog the filter easily and shorten filter life. For the solution with a pre-filtration system, please search for WD-PFK.
