What is new about the Waterdrop D6 RO water filter system?

The five-in-one composite filters in the Waterdrop D6 Water Filtration System combines multiple filtration technologies into one.
The first PP cotton layer filters out sediment, rust, and other large particles.
The activated carbon block layer reduces organic matter and chlorine.
The second PP cotton layer further reduces suspended matter and other impurities.
The reverse osmosis membrane layer has a filtration accuracy of 0.0001μm, which intercepts TDS, salt, nitrates, PFAS, lead, sodium, chromium, benzene, etc.
The post-activated carbon block layer reduces taste and odor to improve the taste of water.

What impurities can D6 RO water system remove?

The FIST composite filter, specially adopting DOW RO membrane can conveniently reduce most of pollutants including TDS, lead, chlorine, salt, nitrates, PFAS, lead, sodium, chromium, benzene, etc. The filtration process also eliminates bad taste and odor, leaving you with clean and great-tasting drinking water.

How to read the TDS? And why are there two numbers?

The faucet offers a real-time TDS display of your water quality at any point in time. The in-built LED and TDS sensors become active when the faucet is on. D6 reverse osmosis filter system has two TDS detectors, detecting TDS level before and after filtration respectively. It shows TDS level before filtration at first and then indicates TDS level after filtration two seconds later.

Does this home reverse osmosis system fit in my under sink?

It’s of 15.98 x 5.98 x 11.97 inches size and is the smallest 600GPD RO system in the market. The D6 adopts a simple tankless design. It requires little space in your kitchen and can conveniently sit under your sink without obstructing your perfect kitchen interior.

How do I install Waterdrop RO water filter system?

Along with a well-organized instruction manual, you can find a step-by-step RO water filter system installation video on the Waterdrop YouTube channel.

How often do I need to change the filter?

Filter use: 12 months or 1,000 gallons, whichever comes first.

What is RO water filter system?

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to reduce ions, unwanted molecules and larger particles from drinking water. The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side.

Does this reverse osmosis water system reduce chromium?

All of our reverse osmosis water filtration system are designed to reduce 94-99% of Chromium-6 in your water.

How well does this RO water filter system reduce nitrates?

All of our reverse osmosis water filter systems are designed to reduce 85-90% of Nitrates in your water.

Does this RO water system remove chemicals used to soften water?

This system will reduce chemicals in the water as well as sodium from a salt-based water softener.

Can this filter be used as a reverse osmosis water system for home?

No. This RO water system is just a point-of-use water treatment system.

Will this reverse osmosis filter system completely reduce fluoride?

All of our reverse osmosis water filtration systems are designed to reduce 94-99% of fluoride in your water.

Is this reverse osmosis water filter system unit suitable for well water?

We do not recommend using well water as source for our RO systems.
The reasons are as follows:
1. Large particles.
Compared to municipal tap water, the well water is rich of large particles, which will clog the filters easily, and shorten their lifetime significantly.Please note that the filters will still need to be replaced more frequently, even if you have added a pre-filtration system.
2. Composition
The well water has very complicated compostion, and some of them (apart from the large particles) can cause the filter or internal valve to be clogged and prevent the RO system from normal performance.
3. Water pressure
The well water may not provide the feed water pressure that the RO system requires (14.5 psi min.). Furthermore, the water pressure will be even lower after passing through pre-filtration systems.

Does this home reverse osmosis system require an under-sink electrical outlet?

Since the system has the booster pump it will require an electrical outlet for the system to work.

Does this RO water filter system remove salt from my water softener?

a. Please note that the water softener is NOT designed to provide drinkable water. Its main function is to soften the water for washing clothes, taking a bath, flushing toilets, etc.

b. If a salt-based water softener is installed BEFORE the RO unit:
-The filtered water could be salty since our unit can only remove 90% salt added by the softener.
-The RO filter's lifetime could be shortened due to the unusual amount of sodium in the source water, which is NOT covered by the warranty.
-We have already put a clear warning on the product page regarding this aspect.

c. If your water softener is NOT salt-based, then our RO unit should work properly with it.

Does this reverse osmosis water filter system lower the pH of the water?

Yes, this reverse osmosis filter system should or could reduce pH but it depends on the source water and the mineral content of the source water.

What does Pure to Drain Rate mean?

The reverse osmosis water filter relies on a semi-permeable membrane to filter out impurities from drinking water. When the tap water is compressed through the RO membrane, it produced pure water and waste water. The ratio of pure water to waste water is called wastewater ratio. 1:1 wastewater ratio means 1 gallon water is wasted per 1 gallon purified, and 2:1 wastewater ratio means 1 gallon water is wasted per 2 gallon purified. The higher the wastewater ratio is, the less waster water produced during the filtration process. During the use of RO water filter, the actual ratio might be lower than the labeled, depending on many factors such as water quality, pH, pressure and temperature.

What is water pressure tank?

The water pressure tank has a design that fits beneath a sink, and the hydropneumatic pressure tank also fits in line with a reverse osmosis system. Additionally, the reverse osmosis tank is for storage; it collects water that the reverse osmosis membrane gradually purifies. Because the reverse osmosis filtration process is slow, water pushes through the semipermeable membrane, a drop at a time. Nevertheless, water accumulates in the tank, allowing you to get immediate access to plenty of water whenever you pour yourself a glass.

How to install the reverse osmosis tank?

The manual contains straightforward instructions on the reverse osmosis tank installation. Out of the box, the tank has a ¼” quick-connect design. You can complete the installation by cutting off the RO system’s water outlet tubing and inserting both ends of the tubing into the tank.

What size small water tank do I need?

This small water tank has dimensions of 4.1×4.1×7.3 inches.

How many gallons is a RO tank?

This tank’s volume is 0.26 gallons.

Can I connect tankless reverse osmosis system to refrigerator/icemaker?

Yes. The under-counter reverse osmosis system is plumbed to an independent faucet, drain, and an incoming cold water line. It would be best to consider pressure when connecting your RO system to your refrigerator because the RO unit’s pressure is about two-thirds of the incoming line pressure.
Fortunately, the pressure tank eliminates problems with water pulse because of inconsistent pressure; This comes in handy when you’re using the refrigerator with other appliances over a long distance, which may cause a delay in filtered water production.
