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.
What is the best ultrafiltration water filter system?
The best ul-trafiltration water filter system should have 3-stage filtration, integrated waterway, zero waste-water, and smart indicating system, which reduce 99.99% of chlorine, odor, and effectively adsorb lead, chloramine, fluoride, heavy metals, VOCs.

Installation was easy, quick and no leakage so far

I am enjoying my Waterdrop TSU way better that any of the filters/purifiers i've used before. It was easy to install, my dad and I were done in under 30 minutes. The water tastes clean without that salty, chemical taste prevalent in some bottled waters. No chlorine taste to speak of either. My favorite part is that the water comes out of a separate "faucet", so we can run water for washing dishes and get drinking water at the same time with little impact on the water flow. I was honestly concerned about leaking from the hoses under the sink, but so far so good. I've had it for a little over 2 months and don't plan on going back to any other type of system.

Great filtration system.

I bought this as a filtration system for our refrigerator and ice maker. With additional fittings purchased from a local hardware store the set up was a breeze. We very hard water in west Texas and I will destroy an ice maker in a about a year. The Waterdrop system is exactly what I need.

Great tasting water

We installed this on our sailboat. It was easy to install and the water tastes great. We use bleach in our water tanks and this removes the odor and taste completely. Highly recommend.
