Difference Between Waterdrop WD-G2P600-W and WD-G3-W

1. Water Flow Rate

Both WD-G2P600-W and WD-G3-W have a fast water flow rate of 400 gallons per day and 0.28 gallons per minute. On average, they can filter a glass of water in about 12 minutes. The two filter water fast than most competitors.

2. Filtered Water to Pure Water Ratio

The 2 models have pure water to waste water ratio of 1:1. Compared to other systems, this is by far the best outcome. For every gallon of water purified, only about a gallon goes to waste.

With other systems, this is never the case; the water that goes into the drain is always more than the purified quantity.

Waterdrop systems save at least 300% more water than standard RO systems hence highly efficient.

3. Design

Both come in a tankless design hence compact and lightweight. The G3 unit is, however, a little bigger than the G2 and only saves about 50% of your under-sink space.G2 saves 70% of the space.

The no-tank design also prevents bacteria growth and water re-contamination.

4. Filtration Stages & Process

WD-G3-W

To produce clear and tasty water, G3 uses 7 stages of filtration. The system uses 3 composite filters for deep filtration.

  • In stage 1 – Sediment PP membrane removes sand, rust, particulates, nematodes, and suspended substances.
  • In stage 2 – The premium carbon block filter removes bad taste, odor, chlorine, fluoride, limescale, and lead.
  • In stage 3 to 5 – 3 layers of RO membrane remove 99.9% of bacteria, heavy metals, and TDS.
  • In Stage 6 to 7 – The activated carbon block further purifies the water, infuses beneficial minerals back to the water, and enhances its taste.

WD-G2P600-W

Waterdrop G2 filters water in a 5-stage filtration process. The system uses 2 composite filters for a deep filtration process.

  • In stage 1 – The pre sediment membrane removes rust, particulates, sand, nematodes, and suspended substances.
  • In Stage 2 – Activated carbon block filter get rids of residual chlorine, large particles, and colloids.
  • In stage 3 – Water passes through a 2nd pre sediment membrane.
  • In stage 4 – The reverse osmosis membrane removes 1,000+ contaminants, heavy metals, bacteria and improves the taste of the water.
  • In stage 5 – Water goes through a 2nd activated carbon block composite filter, which enhances the taste.

5. Safety Features

Waterdrop G2 and G3 use superior protection technology such as insulated materials and integrated waterways to reduce the risk of leakage.

To extend the life expectancy of filters, the G3 can automatically initiate flushing when it works continuously for 2 hours. Also, when no water is dispensed for 24 hours, the G3’s system is automatically flushed to ensure that you get fresh and healthy drinking water at all times.

6. Installation and Maintenance

The 2 models are quite easy to install and maintain. You don’t need to seek professional help to get either of the systems up and running. And the good this is that the package comes with all the hardware need to complete the installation process.

It’ll take you about 45 minutes to set everything up. Also, replacing the filters is a breeze. It’ll take you seconds to get everything done. All you need to do is twist, pull out the old filter and then replace it with a new one.

And how do you tell that it’s time to replace the filters?

The G3 has a smart designer faucet that makes everything easier for you. For example, when the color of the display turns yellow, it indicates that you need to replace the filter soon enough. Likewise, when it turns red, replace the filter immediately.

The G2 has a color reminder as well. Purple indicates that you need to replace the filter soon, and red means that you need to replace them now.

7. Filter Replacement Schedule

AS aforementioned, you’ll need to replace your RO system filters after some time. For example, with the G3, the CF filter requires replacement after every 6 months, the CB filter after a year, and the RO after 2 years of continuous use.

For Waterdrop G2, the CF filter requires replacement after a year and the MRO filter after 2 years of use.

You, however, need to note that hard water conditions can change the timeframe of the filters. You, therefore, need to refer to the individual system’s filter life indicators to remind you when to replace the filters.

8. Certifications

The G3 is both tested and certified by NSF/ANSI standard 58, an authority that deals with the effective removal of different contaminants. G2 is FCC(Federal Communications Commission) compliant but still waiting for NSF certification.

9. Price

Waterdrop G3 comes with a higher price tag when compared to the G2. This is because it’s bigger and boasts more features than the G2.

If working on a budget or have limited space under the sink, the G2 makes the best choice.

10. Warranty

Waterdrop provides a warranty for the systems and filters. There’s a 1-year warranty for the composite filters and a 2-year warranty for the RO membrane filter.

Conclusion

Both the Waterdrop WD-G2P600-W and WD-G3-W have the same design and can remove 99.9% of contaminants in the water. The G3, however, has a 7-stage filtration process that is more thorough and removes more contaminants. As a result, water from this system is slightly smoother.

With the 2 systems, you won’t have to worry about maintenance, thanks to their tankless design. However, if you’re tight on budget, the G2 will work great for you. On the other hand, if smart convenience features are what you crave, get the G3.
