Impressive long service life

According to the EPA, an American family uses 18-22 gallons of tap water every day. With a maximum filtration capacity of 19,000 gallons, the Waterdrop Undersink Water Replacement Filter 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 Replacement Filter reduces PFOA/PFOS, PFAS, pollutants, such as chlorine, taste and odor, rust, sediment, and other heavy metals[2]. You don’t have to worry about the safety of the filtered water.

The filter also retains minerals that are essential to your body, such as potassium, sodium, calcium, 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.

These are fantastic and easy to replace. The water has no taste with these which is great. We do not have the greatest water where we live and this is a perfect solution to it. Very budget friendly and easy to install.

Great replacement! Works as expected and just as good as the original one. Comes with installation instructions. Do make sure you drain the old filter fully or place in plastic bag.

It’s a water filter. Does its job. Tested molecule from the filtered water and it filtered out about 70-80%. Happy with the result.

I use this filter underneath my kitchen sink. It’s great for cooking and you can taste the difference living in Fort Lauderdale. We have really yellow water from the chlorine that they dump in it after it goes to the filter. It is clear as a bell and tastes a whole lot better.

Just replaced the original filter under the kitchen sink. We use this to filter drinking water daily, replaced original after a year. The price is good and we notice a taste difference in the water while using.
