## Description

Waterdrop D6 reverse osmosis system: 𝟔𝟎𝟎 𝐆𝐏𝐃 & 𝟐:𝟏 𝐥𝐨𝐰 𝐝𝐫𝐚𝐢𝐧 𝐫𝐚𝐭𝐢𝐨 & 𝐒𝐦𝐚𝐫𝐭 𝐟𝐚𝐮𝐜𝐞𝐭 & 𝐓𝐚𝐧𝐤𝐥𝐞𝐬𝐬 Design & E𝐚𝐬𝐲 𝐢𝐧𝐬𝐭𝐚𝐥𝐥𝐚𝐭𝐢𝐨𝐧 & N𝐨 𝐥𝐞𝐚𝐤𝐬 𝟔-𝐬𝐭𝐚𝐠𝐞 𝐜𝐨𝐦𝐩𝐨𝐬𝐢𝐭𝐞 𝐟𝐢𝐥𝐭𝐞𝐫 & 𝐞𝐟𝐟𝐞𝐜𝐭𝐢𝐯𝐞 𝐟𝐢𝐥𝐭𝐫𝐚𝐭𝐢𝐨𝐧: Waterdrop D6 water reverse osmosis filter system adopts 6-stage filtration system. The filtration accuracy of reverse osmosis membrane is 0.0001μm. The 6-stage filter reduces pollutants from water, including TDS, lead, chlorine, salt, nitrates, PFAS, lead, sodium, chromium, benzene, etc. The activated carbon block is made from natural coconut shells. Please confirm whether you are allergic to it. 𝟔𝟎𝟎 𝐆𝐏𝐃 & 𝟐:𝟏 𝐥𝐨𝐰 𝐝𝐫𝐚𝐢𝐧 𝐫𝐚𝐭𝐢𝐨: Waterdrop reverse osmosis water system is upgraded to have a flow rate of 600 GPD. With an innovative internal pump and a larger filter surface, you can fill a cup of water in 8 seconds. A low drain ratio of 2:1 means that dispensing 2 cups of pure water produces only 1 cup of wastewater. You can use the wastewater to mop the floor or wash the car. 𝐒𝐦𝐚𝐫𝐭 𝐝𝐞𝐬𝐢𝐠𝐧𝐞𝐫 𝐟𝐚𝐮𝐜𝐞𝐭: The tankless reverse osmosis system comes with a smart designer faucet that has a high-end screen. The screen shows the real-time TDS level and the remaining life of the filter. It is waterproof, so you do not have to worry about electrical leakage. Together with the filter life indicator on the control panel, D6 reverse osmosis filter system saves you time and effort by monitoring these for you. 𝐓𝐚𝐧𝐤𝐥𝐞𝐬𝐬 & 𝐞𝐚𝐬𝐲 𝐢𝐧𝐬𝐭𝐚𝐥𝐥𝐚𝐭𝐢𝐨𝐧: The D6 RO water filter system employs a tankless design and a composite RO filter. Compact D6 RO system saves 70% of your under-sink space and prevents recontamination than traditional system. DIY installation can be completed within 30 minutes. NOTE: An electrical outlet is required to operate the RO system.

Review: This masterfully designed water purifying system is amazing, compact, & relatively easy install. However, you must have access to 110 Volt outlet for it to function, since there's a built-in pump system that generates water flow out of the spigot, far greater than the "water flow, multistage filter system provides. An LED face provides info of water flow, condition of the Uni-Cartridge System, so you know when to replace it... it's a ONE & DONE replacement system... SO EASY! The electrical input lights the LED face as well as pumps water into glass, bottles or pots, and it's flow is remarkably better than the water pressure design. This system takes brilliantly & thoroughly takes out all the chlorine, bromine, particulates, etc., leaving crystal clear drinking & cooking water, that tastes as good or better than purified bottled waters on the market. This system also is most useful to us due to having a very large tropical fish tank, so we use the filter for water addition & water replacement. All the fish literally swim up to get their freshwater bath each week. It does cost a little more than the average Osmosis Pressure Water Purifier but us far more water, faster, more consistently and plentifully. A must if your tap water tastes off, or even terrible. Your family will want to drink more water & less soda with system in your kitchen, wet bar, or even a bathroom sink.
Review: We got this system because my town is currently upgrading its 130y/o pipes and since they started the project, we taste a significant increase in chlorine and other disinfectant chemicals. Also several of my plants began to die as a result of watering them with our tap water. My husband and I are only moderately handy and we installed this system ourselves in 1.5 hours. Super easy install, but I strongly recommend watching a YouTube install video to familiarize yourself first. You'll need a power outlet under your sink, but this system should not interfere with your dishwasher. If you have a garbage disposal on a wall switch, that may create an electrical dilemma for you (we didn't have that issue tho). You'll need a drill with a bit to make a small hole in your drain pipe, and maybe on your countertop if you don't already have a hole for the additional faucet. If you're not about that DIY drill life, then I recommend you get a professional to do install. The quality of the water is OUTSTANDING, like for real I'm not even joking it's the closest we've ever gotten to drinking Icelandic water (if you know you know). The machine that goes under the kitchen sink does take up a bit of space (especially if you have a small cabinet) and it makes a little bit of noise but we just sat it atop an old foam kneeling pad we had and I can barely hear it now. We tried to put the machine in the basement and run the hoses down, but beware the water pressure may suffer for that, we ultimately put it back in the cabinet. The water pressure output from their included faucet is slower than my impatient self likes, but again, the water quality is so superior that I will gladly wait 3 seconds longer to fill my glass. Not sure yet if the 6-12mo filter life is accurate, I'll be back to update on that next year! But for now, one of the best purchases I've made, the price is totally worth the value!

## Questions & Answers

**Q: You have conflicting answers -- 1 says this filters uranium, the other does not. Does this filter uranium?**
A: Hi,
Thanks for your interest in our D6 RO system.
In theory, yes, as a benefit of the RO membrane (filtration accuracy: 0.0001μm), this product should be able to remove uranium from the source water. But please note that it has not been tested in the labor yet.

**Q: What is the downside to not using the remineralization cartridge, and if you do what is the hardness of the output?**
A: I haven’t experienced any “downside “ as the taste of the water is very good. If there’s a need by a consumer for minerals replaced in the water there is a filter to achieve that goal.

**Q: What typw guarantee do you have on this item?**
A: Hi,
Thanks for your interest in our D6 RO system.
Please rest assured that the warranty is 1-year after receipt, and you can return the product within 30 days for a full refund.

*by L***R on 2 May 2021*

(Old Review; scroll down to updated 1/13/2021): Love the taste, so many advantages as others have said. The life of the filter, not so much though so far. Live in Manhattan (NYC) where TDS in around 225, TDS out after 30 seconds anywhere between 4-7 which is remarkable. Purchased the Waterdrop Tankless 600GPD on Jan 27, 2021 and having used it daily for 90 days, making about 2-3 gallons per day for two people, plants and humidifiers. The "life of the filter" indicator light has 6 levels, and now it's down to level 1, indicating the life of the filter is almost over? Not sure if there is an error or problem, but I don't think TDS 225 or NYC water is that dirty. Will contact Waterdrop to confirm. But their estimates were 1 year or 1000 gallons which ever comes first. I'm estimating that we've made 250 gallons so far. While the product's water taste is phenomenal, the annual cost, plus as the filter becomes less efficient more quickly over time producing more waste water and the annual 'filter goes into landfill' waste becomes concerning O_o. Will contact Waterdrop and see what they have to say, will update this review. Updated 1/13/2021: I increased the rating to 5 stars. Why? Well, Waterdrop did get back to me, and gave me a 2nd filter to try. Over the spring, summer, and fall, our use was much less (not feeding the humidifiers) and the filter is down to 3 out of 6 bars. Since the most likely use case for 2 people is probably not to feed humidifiers, I think that about a year or 10-12 months use depending on rate of use is about right. If you feed humidifiers (in total this makes the filter pass probably 2-3x as much water as is used by two people drinking alone in the same time period), expect to pay a lot more. TDS drops from low 200's to low teens after 20-30 seconds and single digits after running the filter for a minute or more and the RO water tastes so clean (not muddy as per my neighbors complaint). We use it for coffee and the soda stream (adding back CO2, is it clean I wonder?). Have there been any malfunctions? Only once early in the use of the filter I had some water leaking around the base, not sure where it was coming from. I just retightened the fittings/couplings and it never leaked again, aside from a little water when I replaced the filter. It wouldn't hurt to get a tray for the unit. I'll estimate that filter replacements of $100 annually for two people using it for personal drinking and occasional cooking is about right. Our use case, we water plants, and fill TWO humidfiers in the north east winters, so will replace the $100 filter twice annually at least. You know what? It's totally worth it. I won't hesitate to install one of these at home again. Enjoying drinking fresh clean water, cooking with it, making coffee and tea with it, and having clean humidifiers without calcification has transformed life. Not paid promotion, I bought this unit off Amz. Hopefully this review continues to help people. This system is great, and I won't hesitate to continue support the company and its products.
