Waterdrop G2 Vs G3: Which One’s a Better Choice in 2023?

Waterdrop-G2-Vs-G3When we talk about reverse osmosis water filtration systems, Waterdrop is the only brand that stands out among the rest in terms of special features, water flow, and safety systems.

This article will help you determine the best features of both the Waterdrop G2 & G3 so that you can decide which one is better according to what you need for your household or commercial use.

Waterdrop G2 Vs G3– Which one’s a better choice?

Differences Between G2 And G3:

Flow Rate of Water:

Waterdrop G3 provides you a great water flow even in conditions where water pressure is low which means in just twelve seconds of time, you will get a glass of water. The G3 provides 400 gallons of water every day which is 0.28 per minute.

According to statistics, a normal family in the US uses about 40 litres of water every day, so if you have a large house with a lot of members or needs, this system is good enough to go.

The flow rate of Waterdrop G2 is comparably faster and more efficient, in just a minute, you can fill up 1.8 litres of purified water achieved through the RO process. The overall water filtration rate is 2271 litres of water per day which means you can either use it for home or offices.

Here’s a video on how to install Waterdrop filter systems:

The scale of Drainage:

The G2 Waterdrop filter is a tankless system which means that the drainage ratio is naturally lower than the tank reverse osmosis system. It has a one-to-three ratio meaning that with two parts of the water that is entered for filtration, one part goes is filtered, which is still a pretty good ratio. The wastewater goes through a different tube while the faucet provides clean and safe filtered water.

Comparatively, the G3 waterdrop filter reverse osmosis tankless system has a one-to-one ratio meaning that with each part of the water that is filtered, one part goes to waste, which is still a pretty good ratio.

Simple Setup & Guidelines: 

Both filter systems have an easy-to-maintain and install setup which anyone can follow through the Do-it-yourself guides present on their websites which means you do not have tons of money for professional installation. The installation manual is easy to follow as well.

Filtration Volume:


Both Waterdrop G2 & G3 remove up to 99.9 percent of bacteria, chemicals, harsh minerals, contaminants, sediments, chlorine, bad taste, and odour from the water resulting in pure and healthy drinking water.

Waterdrop G2 consists of three filters and all three of them come with 7 additional membranes to filter out effectively. The first filter is the composite filter where the impure water must cross through two layers of an activated carbon filter with a coconut shell and polypropylene cotton which effectively removes any total dissolved solids such as sediments, dirt, and chemicals, etc.

The 2nd filter is the RO (reverse osmosis) filter which has microscopic pores that do not allow harmful metals such as arsenic, chromium, and lead as well as different kinds of viruses and bacteria and more organic impurities. The last filter is the carbon block filter that makes sure that the water tastes as it is supposed to: clean, pure, and refreshing.

On the contrary, Waterdrop G3 consists of just two layers with two similar layers but one of them comes in a smaller size, making the filter system much smaller than the G3. The first filter is the same as G3, the composite filter but this one has a single layer of activated carbon filter with a coconut shell and polypropylene cotton,

The second layer is the MRO (membrane composite filter) which comes with its own three layers: the outermost is the polypropylene layer that gets rid of dirt and sediment, the middle layer is a porous DOW reverse osmosis membrane and the innermost core layer consists of carbon block to enhance the taste and smell of water.

Taste of Water:

The Waterdrop filter does not have a remineralizing step so what you receive is water in its purest distilled form which tastes great and healthy. If the minerals are added to water, they might affect its taste but since the Waterdrop filter only filters out impurities and does not use a chemical process, there is no need to worry about the change in taste.

If you want, you can always add an additional filter that adds back the minerals to the water. These minerals can also be replaced by following a proper diet.

Security Aspect:

The Waterdrop filter consists of a total dissolved solids display feature, also a feature that indicates the quality of water after being filtered, and an additional three-light system highlighting the remaining life of the filter cartridges.

There are three lights: red for danger, as in the last warning for replacement of the filter, yellow light for a warning of fifteen days before it goes to a low level, and lastly the blue light indicating the new life of the filter cartridge. Out of the three filters, you will need to replace the CF filter more frequently which means twice a year for the CF filter, the CB filter, and the Reverse osmosis filter both once a year.

The waterdrop filters also have a protective shut-off feature which saves the water from exceeding the waste limit which is around 30 minutes. It also has a flushing feature which helps get rid of any possible impurities or sediments that might clog the path of the filters.

Mainly, if the water quality is bad or harsh, your reverse osmosis water filter system will perform accordingly and will be filtered based on the impurities it has. Normally water is treated with chlorine, which means if it is already treated, it will be easier to purify.


What is the level of customer service satisfaction for both the water filters?

Both water filters provide 24 hours assistance and are quite helpful in terms of providing relevant answers to your problems so in case you have a problem with your product or installation process, just give them a call.

Final thoughts

In conclusion, the choice is yours as to which water filter you decide on, my job was to highlight the main features of both of the filters.

Both filters have great features and are better than most of their counterparts on the market. I would suggest going for the one which suits your needs but the Waterdrop G2 has much better features as compared to the G3.
