Here Are Our Waterdrop G2 Review Findings

With its tankless, compact design, the G2 water filter offers reverse osmosis filtration for an affordable cost. The integrated build combines electrical and water circuits to reduce water waste and improve filtration so that you receive 99% pure water.

The Waterdrop G2 system is a bit smaller than the newer G3 model. Called the G2 Reverse Osmosis Water Filtration System, this filter is meant for small families and households that need a little less water. However, the G2 is still almost as powerful as the Waterdrop G3 models due to its 400 GPD flow rate and comparable filtration.

What We Liked

The Waterdrop G2 is powerful, yet it’s designed to be small and sleek. The best part about this filter is the effective reverse osmosis filtration, which removes the most contaminants from your drinking water. It also fits right under your sink and takes up very little space.

After testing the water quality before and after filtration, we found that it removes almost all contaminants, and this system is faster than many others we’ve tested. For an under sink water filter, you don’t have to wait long to get pure drinking water.

The G2 system uses a TORAY-brand semi-permeable membrane that removes 99% of all toxins. Most water filters don’t even remove 95% of all contaminants. We found that this system removed:

While this is an older model from Waterdrop, the G2 still gets a flow rate of 400 GPD and has a 1 to 1 drain rate. That means that it operates more efficiently with less wasted water. This cuts down on the overall cost of using a water filter, and let’s you fill up your entire drinking glass in less than 12 seconds.

  • Fluoride
  • Chlorine
  • Chloramine
  • Detergents
  • Pesticides
  • Lead
  • Nitrates
  • Sulfates
  • Arsenic

The multi-stage filtration is important to note for the value. Water flows through several filters before it’s dispensed and ready to drink. The composite filter technology is a newer system for water filters. It combines carbon filters and reverse osmosis filtration to remove more than 1,000 contaminants from your water.

The system uses both a CF filter and MRO filter. The CF filter removes sediment, rust, large particles, chlorine, bad tastes, and odors. The MRO filter removes the majority of other contaminants, including micro-toxins. For example, you’ll find that this system can remove bacteria, limescale, and microscopic organic matter that can infect your water. It produces a clean result that tastes incredibly smooth and pure.

Waterdrop also includes multiple warranties to cover the filters and system. This one includes a one-year manufacturer warranty and lifetime customer support. We also found that the customer support system is quick and responsive to any questions that you have. We were able to contact support for installation help and instantly received a walk-through to make set up quick and breezy.

What We Don’t Like

There are some things you can’t avoid with water filters. For example, it requires installation, which takes time to set up. Like all under sink water filtration systems, the Waterdrop G2 needs a second faucet installed. You may also need to drill a small hole into the drainpipe in order to filter out the wastewater.

In addition, the G2 is like any other system that requires you to replace water filters. With this system, you luckily only have to do so once per year.

Note: The design is incredibly easy to work with because of its lightweight and compact design. You’ll only need a few minutes to get set up. However, all of the tools aren’t provided, which is why we think you should take a look at instruction videos for installation beforehand. If you’re not comfortable with plumbing installation, then these videos can clear up a lot of questions.

Benefits of Waterdrop Filters

Tankless Design

Most water filtration devices have one tank or more for separating water from toxins. Reverse osmosis filters with tanks waste more water and lead to more expensive water bills. This is why you always want to look at tankless water filtration first.

The tankless design is part of the savings with the G2 models. Without a tank, you don’t have to worry about cleaning out the tank to maintain water purity. It also saves space under the sink. This single feature also sets it apart from many other reverse osmosis systems on the market.

In addition, the tankless design is innovative, and it’s still hard to find a system that has this compact, sleek look. Without a tank, this system also provides faster water flow for a fast glass of pure drinking water.

Filter Life

With multi-stage filtration and a reverse osmosis membrane, the Waterdrop G2 RO was designed to be very safe and easy to use. The filter life indicator lets you know automatically when you need to change the filter. Since the G2 is a reverse osmosis filtration system, it uses superior filter media to get the most filtration.

Still, you will need to replace the carbon block filters each year, and the RO membrane will likely last 2 to 3 years before it needs to be replaced. While some systems are rated for longer time in between filter replacements, the filter replacement process is very simple, making it easy to replace filters in under a minute.

Quick Installation

As an undersink water filtration system, you don’t have to do much to install the Waterdrop G2. Lightweight, compact, and simple to plug in, you can hook up the G2 in less than 10 minutes and have pure drinking water right to your kitchen faucet.

One of the most important factors to consider is that you’ll need to install a second faucet with this system. The faucet is included with the system. All of the required water lines and hardware come with the installation kit. While you will need the proper tools to install the faucet, it’s pretty straightforward and connects perfectly to all water lines.

Easy Maintenance

You don’t have to worry about cleaning the G2 because it doesn’t have a tank. While you still want to wipe down the filter and possibly the inside during a filter replacement, you don’t need to worry about the tank or filters becoming corroded or having other issues with mold. The system was designed to prevent these problems.

In addition, customers say that it’s easy to get inside of the case to replace filters and simply use a microfiber cloth to wipe down. The most you’ll have to worry about is tightening newly-inserted filters enough to prevent small leaks.

Excellent Product Support and Warranty

Finally, we experienced zero issues with the G2, but we still had questions for customer support. We found that Waterdrop makes it easy to contact their customer service team online or by phone. You can easily resolve issues and talk to their warranty support team.

There are multiple warranties included that cover the filters separately from the system. The CF filter is covered for one year, while the MRO filter has a two-year warranty.

Final Verdict

The Waterdrop G2 RO filter is best suited for smaller families and homes, but it can also work with small offices. With a composite integrated filter and reverse osmosis system, the G2 provides more than effective filtration. It removes 99% of all contaminants and it works almost as well as Waterdrop’s newer filter, the Waterdrop G3. In comparison to the G3, you still get a fast flow rate of 400 GPD and a 1-to-1 drain ratio.

We think you’ll love this little water filter if you’re looking for pure drinking water right in your kitchen for a fraction of the price of bigger under sink RO filtration systems.
