Waterdrop Under-Sink Ultra Filtration System achieves great filtration performance. The innovative filter design allows the system to reduce contaminants while retaining beneficial minerals, providing healthier and safer water for you and your loved ones. With the superior Waterdrop ultrafiltration membrane, the system delivers excellent filtration performance. With a pore size of 0.01 micron, the ultrafiltration membrane can reduce harmful substances. Aside from the PP filter for large impurity removal, the carbon block filter improves the taste and odor, ensuring delicious, safe drinking water. The system does not require an undersink electricity supply, which means you do not have to worry about your power supply under the kitchen cabinet. Therefore, you can drink clean and safe purified water even in emergencies like a power blackout. Unlike other water filtration systems that generate a lot of waste water, this ultra-filtration water filter system produces prime-quality purified water with zero waste water.

What is the rated input water pressure of the ultrafiltration water filter system?
What is the feedwater temperature of this ultra-filtration undersink filtration system?
The feed water temperature of this ultra-filtration undersink filtration system is 41-100℉/ 5-38℃.
How to install the ultra-filtration undersink filtration system?
Step 1: Install the feed water adapter.
Step 2: Install the faucet.
Step 3: Install the batteries and place the system.
Step 4: Connect tubing.
Step 5: Start up the system.
You can get a detailed instruction and a user manual on the product page.
What size of the hole do I need to drill for the faucet of this ultrafiltration system?
It’s recommended to drill a hole of 1″. If there’s a reserved hole for the soap dispenser on your countertop, you could use that to install this faucet directly.
Besides, we have included a sticker in the package, which could be used as a reference while drilling the hole.
How often do I need to change the filter?
Does the ultra-filtration undersink filtration system produce waste-water?
Unlike other water filtration systems that generate a lot of waste-water, Waterdrop ultrafiltration inline filtration system produces prime-quality purified water with zero waste water. Waterdrop understands how valuable water in the fresh tank is, and we are dedicated to delivering purified water that is socially equitable, environmentally sustainable, and economically beneficial.
Does the ultrafiltration undersink water filter system require a wall plug?
The ultrafiltration water system does not require an undersink electricity supply, which means you do not have to worry about your power supply under the kitchen cabinet. The only thing you need is three 4.5V AA batteries. Therefore, you can drink clean and safe purified water even in emergencies like a power blackout.
Do I need plumbing services to install the system?
No. Waterdrop ultrafiltration inline filtration system is designed for DIY installation. You can install the system in 30 minutes. Simply refer to the instruction manual and instructional videos, or contact us by email, phone, or live chat.
What does this ultra-filtration undersink filtration system remove?
This 0.01-micron ultrafiltration membrane can reduce harmful substances larger than 0.01-micron. Including 99.99% of chlorine, odor, and effectively adsorb lead, chloramine, fluoride, heavy metals, VOCs. Besides, this system is not designed for TDS removal, It will retain minerals such as potassium, calcium, sodium, and magnesium, which are beneficial for your health.
How does ultrafiltration membrane work?
UF membrane uses standard home water pressure to push water through a semipermeable membrane and reduce any contaminants. Unlike reverse osmosis, ultrafiltration retains minerals in the water, while filtering out bacteria, viruses, and parasites.
What is the difference between filtration and ultrafiltration?
The main difference between filtration and ultrafiltration is the pore size of the membrane. With each different filtration process, a variety of elements get either blocked or pass through with the water. The 0.01-micron uf membrane of Waterdrop ultra-filtration undersink filtration system reduces 99.99% chlorine and effectively adsorb lead, chloramine, fluoride, heavy metals, VOCs, and much more.
What are the differences between this ultrafiltration system(TSU) and the dual carbon system(TSC)?
The main difference between TSC and TSU are:
Filtration accuracy: TSU 0.01μm / TSC 0.5μm
Different filter: TSC: 3 filters, PP+CS+CT / TSU: 3 filters, PP+UF+CT
The TSU can reduce the bacteria from the source water while the TSC cannot.
What is the difference between ultrafiltration and reverse osmosis?
The ultrafiltration water filter system uses a hollow fiber membrane to stop solid debris and microscopic contaminants. Ultrafiltration is a filter system, while reverse osmosis is a process where molecules are separated. Waterdrop also provides a reverse osmosis water filter system if you need it.
