The Waterdrop RO water filtration system, Product Overview

Everybody pretty much uses water, whether for drinking, cleaning, or taking a bath. There is a saying, “Aqua (water) is life.” This statement is partially true because not all water is right for you.

The human body is made up of 60% water, and water is vital to your existence. Drinking water from a contaminated system can lead to many health problems such as cancer, kidney and liver problems, skin irritation, and unpleasant taste /odor. Is your water free from contaminations?

The waterdrop RO drinking water filtration system uses a Reverse Osmosis advanced technology to provide your home drinking water that is safe and free from contaminations, unpleasant taste, and odors.

It is NSF Certified, smart faucet, 400 GPD fast flow, tankless, reduces TDS, compact, 1:1 drain ratio, UL listed power, USA technology, WD-G3-W.

It is a unique system, and I will be walking you through every detail of the Waterdrop RO Drinking Water Filter within this review.

Unquestionable, it’s an Expensive Filter, But the Cost Savings Are Incredible

In the past, I used to buy bottled water regularly because I didn’t like how tap water tastes. Initially, it didn’t look like much spending a couple of dollars every month, but after getting married, having two kids, and watching them grow, I realized that things get add up. On averages, I was spending $100+ per month on bottled water.

So, I decided to try something new and different to save some money and still drink healthy water. I started first by buying a PUR Classic Faucet Mount Filter, probably for $20 for my home sink faucet, worked effectively initially, but didn’t last long.

I later bought one of those popular refrigerators that gives you filtered water with regular replacement filters. Lastly, I start looking at a reliable faucet filter because my expensive fridge (over $2000) suddenly broke down after the warranty expired.

According to Dr. Steve Czys’s recommendation, every home should be using “Reverse Osmosis System (ROS) in the faucet to ensure 100% free home water contamination from pharmaceuticals, chemicals, and pesticides our water supply.

So, I started doing my research on which brand to buy but ended up very confused because of the numerous and conflicting information about the various ROS products. I noticed something interesting about all the products that made me decided to write a review on every single brand of water filter, starting with Waterdrop ROS.

Yes, it is expensive, but the benefits outweigh the risk of not having it or having some ineffective and cheap brand. If this price is above your budget, I suggest you take a look at the company’s other versions of similar products that are less expensive.

My findings:

Although review shows over 1000s of customers have reviewed a product coming from the United States, and the rating was saying 4.0 or more over 5.0, DOES NOT mean that the product is right. To make the best decision possible, you have followed these tips below if you are on amazon.com.

  1. Scroll to the bottom page where you have the product, technical, and additional information. Look for the best ranking based on categories. It will give your idea of the frequency that people are buying a particular product.
  2. Next, click on the reviews that are between 1.0-3.0. The goal is to read and understand why the customers rate the product low. The reasons are many; it could be that product got damaged during delivery. Customers are bought by other competitors to damage product credibility, or the product didn’t meet claims before the end of the warranty or consumer just complaining because the product failed after many years passed warranty.
  3. Lastly, change the icon that says “Top review” to “Recent review” to see what comments the people recently bought the product have written. The reason being that you can tell if recent customers find the product useful or not. 

Additionally, the other health benefits of having an NSF certified home water filter is unimaginable. You might want to be tempted to buy some of the cheap products in the market, but they are not NSF certified, which means you can’t trust whatever claims their labels have.

Just like I warned in my article about checking the NSF Certified rating before buying any water filter, I was able to locate the waterdrop RO system NSF certification after visiting the company website.

· The RO membrane has 0.0001μm pore sizes, which effectively eliminates over 94% of serious matters, such as heavy metals (lead, mercury, arsenic), and total dissolved solids (TDS), fluoride, limescale. Enjoy healthy and tasty water.

Though it says 99% on the Amazon site, I got 94% of the product’s official website. (one of the reasons to beware of websites with no integrity).

· The installation processes only take a few minutes to complete and 3 seconds for filter replacement via twisting.

What I don’t like about the Waterdrop RO filters?

The warranty: 30-Day Money-Back Guarantee: Though they promise a full refund, what happens if the system breaks down after 30 days expired?

That, to me, is not good, although there are different types of filters with different warranties such as six months (NICF), a year (N3CB), and two years (N2RO).

Another disadvantage is that most RO systems can’t be used for houses that rely on a well water source. The manufacturer warned that most RO systems do NOT recommend using well water as a source.

But if you have to use well water, they suggested you add a pre-filtration system. Because massive particles in well water will clog the filters quickly and shorten filter life. Also, well water may not reach the feed water pressure.

What about the Maintenance? 


This product is straightforward to maintain. Replacement of the filter takes a couple of seconds. To replace the filter, you can choose from three available choices of filters. They include:

  •  WD-G3-N1CF Filter for WD-G3-W Reverse Osmosis System with 6 Months Lifetime
  •  WD-G3-N3CB Filter for WD-G3-W Reverse Osmosis System with 1 Year Lifetime
  •  WD-G3-N2RO Filter for WD-G3-W Reverse Osmosis System with 2 Years Lifetime
  • Other versions do have their own filters.

Like I mentioned before, my only concern is the warranty issue of 30-Day Guarantee 100% money back.

What is my Verdict? Waterdrop RO filter Rocks


After looking at the various advantages of the waterdrop RO system, I will say it has more to offer than other competitions. Comparing the positive and negative reviews of real consumers, and most importantly, the excellent customer service and easy returns/refunds of full money, unlike the other products,

I will RECOMMEND the Waterdrop RO water filtration system. I am a true believer in Reverse Osmosis System in general, and I know many others that LOVE their WATERDROP RO FILTERS.

One downside is the initial investment cost in a water filter of this quality, but you get what you pay for in this case. The filters come backed with a 30-Day warranty, and it is not a throwaway like the $20 water filter or bottled water.

For the sake of your health and that of your families’ health and safety, drinking water that is 100% safe and free from most deadly contaminations is only going to do your health a favor.

Plus, your water is free of taste and odors. What do you have to lose by picking one today? If you don’t like it or don’t do what it claims to do, return it and get your full refund with ease.

I will prefer buying from a retailer like Amazon.com and waterdropfilter.com because they put their Customer Satisfaction as their number priority and have a high degree of honest reviews because of the mixture.


The product website (waterdropfilter.com) has it on sale for $539, and almost 100% of the reviews are 5.0 ratings. Now, you have many options to buy your RO water filter.

If you are a big online shopper like me, Waterdropfilter.com (cheapest, free shipping, excellent customer services, directly from the manufacturer) and Amazon.com (also two days free shipping with Prime, high chance of honest reviews, and almost similar benefits) will be your best belt on this ROS water filter.

  1. I have been considering getting a water filtration system and this looks like it might be just the right thing. Can I ask you about the installation. Is this something I could do on my own or should I hire a professional?

    • Hi Catherine,
      Thanks for visiting and taking the time to leave a comment.
      That’s a great question because I asked myself the same thing and went to check all the negative reviews about the products on Amazon.com, and there was no complaint about having an issue with installation. If you follow the instruction manual correctly, I don’t think you will have any problem with the installation or need to hire a professional. I hope this helps.


  2. I agree with you, not all water is good for us. I was looking at these filtration systems but I couldn’t find a good review. That is, until now. Thanks for sharing your review of Waterdrop water filtration system. It is a bit pricey, but you can put a price on clean water. Thanks again, and keep up the good work!
