With a maximum filtration capacity of 19,000 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.

With a filtration accuracy of 0.5 μm, the Waterdrop Undersink Water Filtration System reduces pσllutants, such as chlorine, taste and odor, sediment, rust, and other heavy metals.[2] You don’t have to worry about the safety of the filtered water.

The system also retains minerals that are essential to your body, such as potassium, calcium, sodium, and magnesium. Enjoy fresh water with Waterdrop.

Essential minerals

Calcium is one of the most abundant metal elements in the human body. It plays a vital role in the physiological and biochemical processes of organisms and cells. 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.

Home use—kitchen

The system filters out pσllutants while retaining beneficial elements. It’s ideal for cooking, washing fruits and vegetables, and washing dishes. You can cook with pure filtered water and enjoy safe and delicious meals.

Office use—break room

The adequate water supply meets the water needs in your office. The system works without electricity and doesn’t produce waste water. You can directly connect the system to the original faucet, or you can install a Waterdrop Quick Connect Undersink Filtration System with a dedicated faucet.

Outdoor use—RV

The system is ideal for RV using. With the efficient filtration performance, the system delivers tasty purified water to meet with your various outdoor water needs. The specially added KDF ensure the filter hygiene even during non-camping season. The compact design saves much under sink space and brings more room for storage, say farewell to the bulky bottled water. For the ultimate RV water purification experience, please use along with Waterdrop RV Inline Filter.

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 iṁpurities water contains. But what are iṁpurities on earth? No matter beneficial natural minerals or harmful substances, they are all regarded as iṁpurities 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 pσllutants 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-UB filtration system is equipped with a faucet, and can not be connected with your orginal kitchen faucet. If you have a need of this, please choose WD-UA series like B085FYGBX7.

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.
