Waterdrop G2 RO Water Filter Review

The Waterdrop G2 has a three-stage filtration process that removes all impurities. First, the carbon block and pre-sediment filter use a combination to become a 3-in-1 water filter. There are highly activated carbon granules inside the carbon filter.

Also, there is no water tank like you find in the traditional RO filters. It uses a new technology that takes advantage of composite filters that do not require a water storage tank.

Therefore, the RO filter uses a design that equals more than a 3-stage filtration system. Hence, you can get an idea about the quality of drinking water using it. Let’s take a look at its features.


The Filters

There are the pre-sediment, carbon block, and RO filters for the Waterdrop G2 filter system. The first stage is the 3-in-1 pre-sediment and carbon filter. Also, these remove dirt, sand, hair, TDS, and other waste particles from tap water.

The carbon block filter removes herbicides, pesticides, chemicals, chlorine and improves the taste of water. There are high-quality activated carbon granules, and it uses a natural coconut shell. After these filtration stages, the tap water passes through the RO filter.

So, the reverse osmosis layer removes up to 0.0001 microns of impurities. Plus, it uses composite filters that do not require replacement after every six months.


The filter composition technology ensures the compactness and effectiveness of the system. So, the advanced composite filters are integrated in such a way that the filter remains compact. Plus, these filters are effective in removing water pollutants from the tap or municipal water. There is a CF filter that utilizes the sediment PP membrane and activated carbon filter. Therefore, it reduces large particles, colloids, limescale, and rust. These filters also soften water for better taste and smell. Another benefit of this Composite System is the MRO filter that also uses a sediment membrane. Thus, there will be no TDS or heavy metals in the freshwater.


The Design

There is no tank for the Waterdrop G2 water filtration system. That is the reason why it is only 5.9 inches wide. So, it takes a little space under the sink. You can install it within a few minutes because of its easy-to-install design. It will save almost 70% of space under the sink.

Most of the RO systems take a lot of space. They do not have composite filters. Thus, there is the benefit of its compact design. There are notification lights that will notify about safe usage. Also, there are filter life indicators to indicate filter service. All of the materials and construction uses a lead-free design.



The Waterdrop G2 RO filter comes with a built-in pump. Thus, the filters and the internal pump provide a fast water flow rate of 400 GPD. You can get a glass of pure water within 12 seconds. That is why it saves time. There is a stable water flow rate, unlike other RO systems. Most of the RO filters provide drinking water for up to 2 minutes.

However, it will deliver fresh water constantly. The design is compact and easy to install within half an hour. Removing the filters is easy because of the twist and pull design. You also do not have to replace the filter every six months.


Because of the composite water filter, the G2 RO filter saves space and delivers high-quality drinking water. The flow rate is up to 400 gallons daily. So, it is enough for a medium-sized family or office. All of the materials are lead-free and safe to use. It removes colloids, heavy metals, chemicals, and all other water pollutants.

Installation is easy, and the filter cartridges last more than a year. However, it is best for tap or municipal water. Plus, you cannot use it for well water. There are NSF and ASNSI certifications for the system. It is also environmentally friendly.
