With a maximum filtration capacity of 8,000 gallons, the Waterdrop Undersink Water Filtration System can meet a tap water consumption of 22 gallons a day, which will satisfy your daily water needs. Meanwhile, some of undersink filtration systems claim that they have a filtration capacity of 1,500 gallons, producing 4 gallons of filtered water a day, which actually cannot satisfy your daily water needs.
The multistage filtration ensures a great user experience.

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.
What is the difference between the WD-UA system and the WD-UB system?
The WD-UA system does not come with a faucet. It will connect to your existing faucet. Meanwhile, the WD-UB system comes with an additional water faucet.
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.
