Here Are Our Waterdrop G3 Review Findings

Looking for a no-fuss under sink water filter? Waterdrop probably comes up in the top searches for reverse osmosis under sink filters. With high ratings and excellent water quality scores, the G3 is NSF-certified and provides superior filtration.

Most under sink water filters have large storage tanks that take up tons of space and waste a lot of water. This is another reason that the Waterdrop G3 is so highly reviewed by customers. Measuring just 5.7 inches wide with a tankless design, the Waterdrop G3 takes up hardly any room under the sink.

However, the most important feature of all is the powerful filtration. Whole house filtration systems typically use reverse osmosis filtration because it’s the strongest membrane and can filter out 99% of all contaminants.

The Waterdrop G3 offers a multi-stage filtration system with carbon block filters as well as reverse osmosis membranes. This enables a better filter performance overall, even over the mighty Waterdrop G2. Click here to read the comparison review of the Waterdrop G2 vs G3.

Even with its premium price point, the Waterdrop G3 provides amazing value and saves you money, thanks to its design. It’s also one of the more affordable premium filtration systems to include a reverse osmosis design without a tank. With a 1:1 drain water ratio, you also won’t waste as much water as with other filtration systems.

What We Liked

We tested and reviewed the Waterdrop G3 filter extensively. We looked at its reverse osmosis tankless design and tests the results before and after installation. The Waterdrop G3 removed over 1,000 contaminants and delivered a pure, high-quality result.

However, in addition to these results, Waterdrop G3 includes a lot of premium features to make it so much easier to set up and use this under sink water filtration system. With its award-winning design, the Waterdrop G3 includes three different filters, an LED display that shows the water quality, and offers a flow rate of 400 GPD.

The G3 filtration system removes almost all contaminants, including lead, limescale, fluoride, heavy metals, chlorine, and many other harmful substances. Thanks to the multi-stage filtration design, your water is completely safe to drink right at the sink or use for cooking.

The Waterdrop G3 has a three-stage pre-filter using carbon block. This removes larger particles, sediment, and rust. After water moves through this pre-filter, it moves through another three-stage reverse osmosis filter that removes contaminants as miniscule as 0.0001ÎĽm. We found that it was able to remove 99% of all contaminants.

The activated carbon filter removes all bad odors and taste, leaving you with a refreshing glass of water.

In addition, water comes out swiftly and smoothly. In less than 12 seconds, you’ll have pure, clean water that tastes refreshing and has zero odors. We were very pleased with the results.

Best of all, there’s hardly any waste with this system, so if you are worried about utility bills, you don’t have to worry. The G3 has a 1:1 drain ratio, which means that it reduces waste water and saves up to 300% of water resources.

It also comes with an internal pump that increases the flow rate, making it possible to filter out 400 gallons of water per day. You can basically clean 0.27 gallons or about 1 liter of clean water per minute.

What We Don’t Like

Some drawbacks to this system include the second faucet installation and filter replacement. While Waterdrop makes the installation as easy as possible, it’s still requires about 10 to 15 minutes of your time to get set up before you can use the filter.

Compact and small in size, the G3 is easy to place under the sink, but you may need some tools to attach water lines and install the second faucet next to your kitchen sink.

Finally, filters will need to be replaced regularly. The specifications state that the carbon filters will need to be replaced each year, but the RO membrane can last for up to 3 years.

Benefits of Waterdrop Filters

Tankless Design

When you start researching under sink filtration systems, you’ll notice that many have large storage tanks. These take up a lot of room under the sink and make it difficult for you to store anything else but the water filter under your kitchen sink.

Waterdrop’s tankless designs get rid of these issues completely. The sleek and lightweight design is very minimal but smart, allowing you to place it in the back corner of your kitchen cabinet and forget about it.

The compact design is just 5.7 inches wide, saving tons of space but also removing any issues with tank maintenance and mildew. You also don’t need to mount this simple design, and it comes with a leak protector that automatically shuts off the filter if it detects an issue. This prevents any water damage or leaks from ruining your kitchen cabinets.

Filter Life

The Waterdrop G3 is one of the first designs to have a composite filter and reverse osmosis membrane. Both of these filters are included with the Waterdrop G3. However, you will need to replace the carbon block filters once per year. This is common with most water filters and actually shouldn’t be an issue, thanks to the way that the G3 is designed.

You simply watch the LED indicator to show you water quality and filter life, and once it notifies you that a filter needs to be changed, you pop open the case and replace the filter with a new one. It’s a simple plug and play design.

The RO membrane will likely have to be replaced after 2 to 3 years, although this depends on daily use. The LED indicator will let you know when the membrane has degraded and must be replaced.

Quick Installation

There’s nothing more frustrating than installing something you don’t know anything about, but Waterdrop makes it easy to connect the G3. You simply follow the instructions or take a look at the G3 water filter installation video below to install correctly. It takes about 15 minutes to complete, and you may need some additional tools to install the second faucet next to your sink.

Everything is included with the G3 package for a simpler installation, so you won’t need to buy any tubes, water lines, screws, or second faucet. All of this is provided in the G3 package.

Excellent Product Support and Warranty

When it comes to product warranties and support, Waterdrop doesn’t skimp on customer service. You can clearly find all of the warranty information in their product descriptions, and you can log on to their website for online support or call their support line for fast answers and repairs.

The warranty covers the filters and build for up to two years. If anything happens to these components, you can have them quickly replaced under Waterdrop’s policy.

Their customer support was friendly and helpful when questioned about installation. We were given a walkthrough and shown a video while also receiving quick answers to any questions that came up in the process.

Waterdrop G3 Review: Conclusion

With so many water filters on the market, it can be difficult to find one that’s simple and affordable to use. With its multi-stage filtration and smart features, the Waterdrop G3 is one of the top under sink filters on the market. It’s won awards and has a nearly perfect customer rating.

The Waterdrop G3 is worth the cost for absolutely pure drinking water that will keep you healthy, and thanks to its design, it works just as fast as your typical kitchen faucet and doesn’t waste any water. We think this makes it the perfect addition to any home or office looking for great-tasting, purified water for life.
