Are you researching water filters to ensure your family drinks the healthiest water possible? Considering Waterdrop water filters for your home or an easy under-sink water filter? If you’re seeking the best Waterdrop water filter for your home and health, I’d like to share why I chose the Waterdrop under-sink water filtration system, specifically their reverse osmosis water filter that reintroduces minerals into your drinking water after filtration.

Before diving in, it’s important to note that I’m not an expert on water filters or DIY installations. I’m just a mom committed to living healthily and making informed choices, especially when it comes to water—a crucial aspect of wellness. I consume a significant amount of water myself and encourage my clients to do the same. Naturally, I want my family to lead healthy lives by drinking ample water!

Why an Under Sink Water Filtration System?

Are you concerned about the quality of your tap water? In my town, we deal with extremely hard water, which not only damages household appliances but also leaves a film in our toilets and showers and causes buildup in faucets. Although I know the water here is safe to drink, I began to question whether it was truly the best option for my family. There’s a difference between water being “safe” and being the “best” for consumption.Watching the documentary “Down to Earth” on Netflix last year, particularly the episode on water featuring Zac Effron and Darin Olien, was eye-opening. They discussed the importance of minerals in water, affecting flavor and potentially providing health benefits. This prompted me to start researching ways to upgrade our home water system.

Like many American households, our refrigerator has a filtered water dispenser. While it’s convenient for the occasional glass of water, it has its limitations. It’s messy and difficult to fill water bottles due to its design, and it dispenses water slowly—you have to stand there the whole time. Additionally, for safety reasons, it only dispenses about 20 ounces at a time, which was frustrating given how much water we go through in our house. We often resorted to using tap water to fill our water bottles.

I also feel extremely guilty about buying disposable plastic water bottles for convenience. Pre-packaged bottled water for daily use is a hard “no” for me. It’s not sustainable, and most bottled water has little oversight in terms of quality, often being no better than tap water. Buying a filter is not only better for you and the planet but also saves money in the long run.Let’s prioritize both our health and our environment by making informed choices about the water we consume. A good water filtration system can make a significant difference in the quality and taste of your drinking water, without the waste and environmental impact of single-use plastic bottles.

Why Chose Waterdrop


Since we really enjoy the taste of our fridge water, I decided to identify the filter brand inside—Waterdrop! Excitedly, I visited their website and discovered they offer numerous water filtration systems. Admittedly, the array of options felt a bit overwhelming.

My primary goals were clear: I wanted to filter contaminants from our tap water, have a dedicated faucet for dispensing filtered water (eliminating the mess and awkwardness at the fridge), add essential minerals back into the water, and ensure easy installation and maintenance without the need for professional assistance.Wanting to make an informed decision, I delved into Google and YouTube for research. After learning extensively, I consistently found myself drawn back to the Waterdrop system. Here’s why:

Waterdrop boasts an impressive 1:1 filtration-to-waste ratio, unlike other brands with a less efficient 3:1 ratio. This means minimal water wastage, translating to savings on the water bill and reduced environmental impact.

Waterdrop uses natural coconut shell in their activated carbon filters, prioritizing sustainability and effectiveness.

The Waterdrop system is exceptionally easy to install, with comprehensive instructional videos and directions, making it accessible to anyone with basic DIY skills and tools.

It’s the only remineralization system I found with such a straightforward setup and installation process.

The system includes a dedicated countertop faucet for filtered water, offering quick and efficient dispensing compared to our fridge filter.

Clear indicator lights notify you well in advance when it’s time to replace filters, which typically last 12-24 months depending on water quality.

The remineralization canister provides essential minerals for up to 12 months.

The system operates quietly and fits neatly underneath the cabinet, as shown in the images.

Waterdrop enjoys excellent reviews for product satisfaction and customer service.

We opted to install the system near our prep sink, conveniently located opposite the fridge for easy access to ice and water. We replaced the existing soap dispenser with the Waterdrop faucet, despite its mismatch with our other fixtures—though that’s a minor concern for me. If you don’t have a suitable existing hole, installation can be done DIY or by a professional depending on your countertop material.As a word of warning—kids will inevitably treat the faucet like a bubbler!

In the image, you can see the under-sink installation. While it may appear complex, following the provided directions makes the process straightforward. We needed an electric outlet, so we drilled a hole to access one on the other side of the cabinet since our sink is in the kitchen island. Typically, a main sink setup would have a readily available outlet.Before purchasing, I recommend thoroughly checking product dimensions and requirements to ensure compatibility with your space.The remineralization canister, installed on the cabinet wall outside the filtration system, reintroduces minerals into the water before it reaches the faucet for dispensing. I hope this

Waterdrop Reverse Osmosis System Review



The Waterdrop G3 is a robust NSF-certified undersink reverse osmosis system, delivering outstanding features, a sleek compact design, and ample clean, pure water for you and your family.

The Waterdrop G3 is a highly efficient system, producing approximately 1 gallon of waste water for every 2 gallons of pure water produced (2:1 ratio).The amount of water waste can vary based on the incoming water pressure, with higher pressure resulting in less waste. Wastewater is generated because reverse osmosis systems use pre-filtered water to clean the filter membranes.

The integrated pump in the Waterdrop G3 boosts the pressure, reducing waste and enhancing efficiency.Waterdrop’s commitment to the reverse osmosis filtration process is evident in their engineering of high-quality products aimed at maximizing performance and sustainability.


Tankless Design: The tankless design makes installation easier and saves space under the sink.

Easy Filter Installation: The filter design is user-friendly, preventing installation errors.

Integrated Feedback Systems: You receive real-time updates on filter status and water quality.

High Water Output: Produces up to 600 gallons of pure water per day, ensuring an ample supply.

Integrated Pump: Increases efficiency and reduces water wastage compared to traditional systems.

NSF/ANSI 58 Certified: Certified for TDS (Total Dissolved Solids) Reduction, a rare certification among RO systems.

These features make the Waterdrop G3 a standout choice for efficient and effective water purification.


Flow Rate: The flow from the faucet is not the fastest, although it is still very good for most household needs.

Lower Water Pressure for Refrigerator Connection: Connecting to a refrigerator may result in lower water pressure compared to what you’re accustomed to. Systems with pressurized storage tanks are typically better for ice makers.

Bonus Features

While the Waterdrop CoreRO system does not include a UV filtration stage, Waterdrop offers this feature in their G3 P800 system for added protection against bacteria and microorganisms in the water supply.
