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 I connect it to the original kitchen faucet?
WD-TSB filtration system is equipped with a faucet, and can’t be connected with your orginal kitchen faucet. If you have a need of this, please choose WD-TSA series like B08P58F9SG.
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.
