Choosing the right Reverse Osmosis system for you and your family is not easy with so many factors to consider and so many good options available. So, we leveraged our extensive experience in water filtration systems to create this article with an in-depth review of the Waterdrop G3 Reverse Osmosis system, to help you decide if this is the right choice for you.
In our view, the Waterdrop G3 Reverse Osmosis is the best RO system available and is our top recommendation, as this NSF-certified RO system combines great design features with a powerful and efficient filtration process.
In this comprehensive Waterdrop G3 Reverse Osmosis review we will analyze the filtration capabilities, the system design features, its performance, its capacity, the installation & maintenance process, discuss customer reviews, and potential alternatives for this Reverse Osmosis system.
Let’s get started!
Waterdrop G3 Reverse Osmosis System Overview
The Waterdrop G3 Reverse Osmosis is a point-of-use (POU) system capable of reducing up to 99% of TDS (total dissolved solids) removing all the contaminants from your water. This RO system is installed under the sink to give you clean water to drink and cook in your kitchen faucet.
The Waterdrop G3 Reverse Osmosis is a top RO system because it combines several great features:
- It has NSF certifications to prove that was independently tested to remove contaminants as described
- Its tankless design allows an easier installation and maintenance, and also saves space under-the-sink
- It has one of the lowest waste water ratio for Reverse Osmosis systems, so you won’t waste as much water as you would with other comparable systems
- It combines 7-stages of filtration removing 99% of harmful contaminants from the water
- It can produce up to 400 gallons of filtered water per day, so you will have enough filtered water for you and your family
- It has many in-built smart monitoring capabilities to let you know the purity of the water, the status of the filters, and help preventing any incidents with the system
So, if you are looking for a Reverse Osmosis system, the Waterdrop G3 is one of the best choices you can make.
Waterdrop G3 Reverse Osmosis Filtration Capabilities
The Waterdrop G3 RO system has two NSF certifications:
- NSF 58: this certification is for TDS reduction, ensuring that the system can effectively reduce TDS in water and remove most contaminants such as fluoride, heavy metals, and many others
- NSF 372: this certification ensures that the system is made of lead-free materials
This system is capable of removing so many contaminants because it combines 7-stages of filtration split into three different filters, using advanced composite filter technology to combine different filter materials into one, reducing the frequency of filter replacements.
The composition of the Waterdrop G3 Reverse Osmosis system is the following:
- CF Filter: The first filter provides the initial 3 stages of filtration through a PP-cotton layer, an activated carbon layer with 0.8-micron pore size, and a second PP-cotton layer
- RO Filter: An huge 3-layer RO membrane of 0.0001-micron pore size
- CB Filter. A final post activated carbon filter with 0.5-micron pore size, used to improve water taste
This powerful filtration process ensures that more than 1.000 harmful contaminants are removed from your water, like chlorine, chloramine, bad taste and odor, sand, rust, heavy metals, limescale, bacteria, viruses, fluoride, asbestos, benzene, lindane, phenytoin, nitrate/nitrite, trichloromethane, chlordane, PFOA & PFOS, etc.
Waterdrop G3 Reverse Osmosis Design Features
The Waterdrop G3 Reverse Osmosis system has several design features, which, in our opinion, differentiate this system from the competition.
Its tankless design not only saves space under the sink but also avoids bacteria formation, ensuring better water quality.
The Smart Designer Faucet looks nice and includes a smart life indicator to let you know when the filters need to be replaced. The blue light on the faucet means that the filters are good, a yellow light indicates that they need to be replaced soon, and a red light indicates that they need to be replaced now.
The Waterdrop G3 RO systems TDS monitoring panel displays in real-time the quality of the water, showing the TDS (total dissolved solids) count of the water that is being filtered.
This RO system also includes automatic flushing which is great to extend the life expectancy of the filters. Basically, when the system reaches a cumulative of 2 hours of usage, the system automatically flushes its filters.
And its holiday mode ensures that you always have access to fresh water when using the machine because it detects no usage for 24 hours, it automatically flushes for 1 minute.
The Waterdrop G3 includes an overworked reminder in which the device starts beeping for 3 minutes if the system has been working continuously for 30 minutes, and after the 3 minutes the system automatically turns off. So, if you let your faucet open by mistake, the system will let you know and protect you from it.
Another safety feature is the starting and stopping frequently reminder, that when the booster pump starts and stops multiple times in a 20 minute period, will beep 5 times and stop producing filtered water.
And the leakage protection functionality will automatically shut off, buzz, and display an error message if a leak is detected, ensuring the safety of the surrounding area.
Waterdrop G3 Reverse Osmosis Performance
Waterdrop G3 Reverse Osmosis performance is top when compared with other RO systems. This device has a 1:1 low drain ratio, which means that only produces 1 gallon of waste water for each gallon of water filtered.
The common waste water ratio of a good Reverse Osmosis system is 1:3, so Waterdrop G3 has a 300% better efficiency performance than the average.
This not only saves water and reduces your water bill, but also protects the environment because you are wasting less water than expected.
Waterdrop G3 Reverse Osmosis Capacity
The Waterdrop G3 Reverse Osmosis system can filter up to 400 gallons of water in a day (GPD), much better than the average 75 GPD of a typical RO system.
And due to its tankless design, the water is filtered at the moment, so you don’t have to wait for the tank to fill.
To ensure a great capacity, this RO system uses an internal pump that produces a faster water flow that can fill a cup of water in just 12 seconds.
Even if you have a large family, lacking enough filtered water won’t be a problem with this RO system.
Waterdrop G3 Reverse Osmosis Installation & Maintenance
Installing a RO system is not as easy as installing other types of water filters, because you will need to drill a hole in your sink (some sinks already have a pre-drilled hole) and connect your pipes to the system.
But due to its tankless design, small size, and because it comes partially pre-assembled, the Waterdrop G3 RO system is easy to install, and on average can be installed in less than 30 minutes (unless you have to open a hole in the sink).
You should follow the manufacturer’s instructions to connect the system to the water line, drain, and faucet. This last part can be the most difficult if an extra pre-drilled holed is not available. In that case, if you don’t like DYI activities, it might be better to call an expert to do the installation for you.
After installing the Waterdrop G3 Reverse Osmosis system you need to flush it for 30 minutes. While flushing the blue light will flash blue and once the process is completed it will stop flashing, to let you know when it’s done. It is a good idea to collect and use this water to water plants or something like that because you should not drink this water.
Regarding maintenance, the Waterdrop G3 makes it really simple. All the smart features mentioned before will automatically take care of the system for you, and the only thing that you need to do manually is to change the filters.
But the system is designed to make this really quick and easy: in just a few seconds you should be able to change the filter as you only need to turn it in to remove and insert the new one.
