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 removes organic matter and chlorine.

The second PP cotton layer further removes 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 removes 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 remove 99.99% 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.

What is RO water filter system?

Reverse osmosis (RO) is a water purification process that uses a partially permeable membrane to remove 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.

Great quality small size 600 GPD RO system with an amazing faucet and a few minor issues

This is probably one of the smallest if not the smallest tankless RO system that I've seen. So small that we almost ended up being able to keep the Insinkerator under the sink "and" install this adjacent to it. Now that's amazing for an RO system of this quality.
One advantage (can be considered a disadvantage too) is that this RO system only runs on 1 single filter with five stages of filtering that supposedly does everything. On the plus side, it takes way less space and on the downside, you have to replace the filter faster and the filter is also more expensive, but believe me, it's well worth it when you get to save more of the precious space underneath your sink. However, if you have hard water with sediments, I would recommend adding pre-filtration to save money on filters and extend the life of the system.
The installation is relatively easy and takes less than an hour (including the faucet installation), the only thing that you might have to do is drill a hole for the drain and there rest is plug and play lol
The capacity is 600 Gallon Per Day which is amazingly high again for such a small system that is tankless and the drain is also pretty low.
Another cool thing about it is the nice looking and smart faucet that's included. Most newer RO systems have a TDS monitor but you usually have to check under the sink. On this RO system, they integrated the TDS display in the faucet so you can always see what kind of a water you are drinking. It also shows you the life of your filter which again eliminates the need to continuously check under the sink.
It is pretty quiet in general, if you close the cabinet door you won't hear it outside of the kitchen even when it's working in full capacity.
One minor downside is the drain ratio, most other good tankless RO systems have a 2:1 purified to wastewater ratio meaning for every 2 gallons of purifies water they generate 1 gallon of wastewater. This Waterdrop system However, only generates 1.5 Gallons of purified water with the same 1 gallon of wastewater. In other words, the 600 Gallon Per Day capacity if 100% used, would generate around 400 Gallons of wastewater, while other better RO systems only generate 300 Gallons of wastewater.
Another minor disadvantage is that Frizzlife has this thing called remineralization that adds some minerals and some nice taste to the water but this Waterdrop system doesn't remineralizer and cannot add taste to the water.
I personally expected 600 GPD to have way faster flow but tbh it's still disappointing. It can never give you the pressure you were getting with systems with tanks but obviously you get the benefit of saving a lot of space.
One last minor disadvantage that might seem unimportant but believe me it is, is that the filter on this RO system can only be replaced from the back, which makes it really inconvenient and burdensome.
Overall, a very nice compact system of high quality and very high GPD capacity that I strongly recommend. I dropped one star for expensive filter that need to be frequently replaced, for the lack of remineralization, for the 1.5:1 drain ratio instead of the better 2:1 and the fact that filter replacement is done from the back and can be a headache.

Great buy. Right choice!!

Installation was relatively easy. There was one step to put the lock on the tubes which was a little tricky. The locks were so small to quickly perform. The taste of water is great. No metal taste or color. Looks sleek, quiet and effective. Very happy with the purchase. I have recommended to many of my friends already.

Waterdrop RO Reverse Osmosis Water Filtration System

Easy to install. Water taste great. The compact size of the unit makes for reducing space needed to install. Mostly uses vertical space, the horizontal footprint is quite small for what it does. The pump isn't completely silent but is much quieter than I imagined it would be. I can barely hear it while the cabinet doors are closed, and it also only runs while the faucet is on.
