Waterdrop WD-G3 Reverse Osmosis RO water filter: Price, Performance & Installation

Waterdrop WD-G3 RO water purifier (Price, Performance & Installation)

If you’ve done some research on reverse osmosis water filters or have one at your home, you already know some of the weak points.

The most familiar of those is the product water to the reject water ratio. Some cheap RO purifiers would take 9 gallons of tap water to serve you only 1 gallon of purified water.

So, those waste a lot of water. As a result, many people nowadays look for a RO water filter that has a better waste and product water ratio.

In this article, we’ll be introducing you with a RO purifier that is currently the most efficient in utilizing tap water. The name of the product is the Waterdrop WD-G3 RO purifier.

We’ll be covering all the aspects of the filter- why it is so efficient, how you can install it, how much maintenance it requires, and so on. So, stay tuned.

A little introduction with the Waterdrop brand

Before we begin talking about the product, you should get some basic knowledge about the brand.

Since its inception, the Waterdrop brand is working relentlessly to provide its consumers with quality water products. It has over 100 patents on its water-based researches.

That’s not all. With these many patents, they have a variety of innovative products available for you. But, the most prominent of those is its RO filtration systems.

With elegant and smart design, they have quickly become one of the big players in the water filter industry. The Waterdrop WD-G3 bears the testimony of its versatile product list.

By now, you have a little introduction to the brand. So, let’s take a look at the product itself.

Highlighted Features of the Waterdrop WD-G3 RO water filter

What are the components of the Waterdrop WD-G3 RO water purifier?

Now, let’s start by talking more about the features the product offers. But, let’s first check out what will be inside the package.

  • System Housing
  • Activated Carbon Filter
  • Pre-sediment and Carbon block filter
  • Reverse Osmosis membrane filter
  • RO faucet
  • Feedwater adaptor
  • Power adapter
  • Drain water saddle
  • Tubings and clips

How many stages are inside the Waterdrop WD-G3 water filter?

The Waterdrop WD-G3 Reverse osmosis water filter comes with seven stages of filtration combining three different types.

The first stage is the carbon block filter. It consists of blocks of activated carbon that will reduce the organic wastes from the water.

The supply water consists of pollutants like odor, Chlorine, Chloramine, and other organic and inorganic particles. The Carbon block filter gets rid of those.

Then, the water will enter the sediment filter. If the tap water carries any clay, sand, or pieces of debris, the sediment filter will remove those.

After that, water will go into the RO membrane. It will remove most of the dissolved solids from your drinking water. 

So, you see, the composite filtration technology gives you pure and fresh water, reducing 99% of the contaminants and 94% TDS.

Why does the Waterdrop WD-G3 water purifier have no tank?

The Waterdrop RO purifier comes with an internal booster pump, which increases the flow rate inside the device. As purification happens fast, it doesn’t need a tank to store water.

What we see in most conventional RO purifiers is the presence of the tank. The tank is vital as filtering through the RO membrane takes time.

Therefore, the purifier stores pure water in the tank. And, as soon as you open the faucet, water comes out of the tank.

The booster pump of the WD-G3 filter ensures that water passes through the RO membrane fast. Due to the high pressure, it can serve you pure water without storing it beforehand.

The good thing about not having a tank is that it gives you more space. Also, as water will get out directly, there can be no further pollution from the tank.

How much water does the Waterdrop WD-G3 waste?

The Waterdrop WD-G3 RO water filter has a drain to output pure water ratio of 1:1. It means it will only waste 1 gallon of water to produce you 1 gallon of pure water.

The RO purifiers are notorious for wasting a lot of tap water. Most reverse osmosis systems would waste 6-7 glasses of water to give you only one glass of pure water.

So, you see, the product can significantly save you a lot of your tap water costs. With the booster pump, it will provide you a glass of water within only 12 seconds.

Why does the Waterdrop WD-G3 water filter use electricity?

The internal booster pump of this model of Waterdrop RO purifiers requires electricity to boost your incoming water pressure.

You may have already observed most of the conventional RO purifiers don’t need any electricity. They only use the inline tap water pressure to purify the water.

As a result, purification takes a lot of time. Moreover, if the input water pressure is low, the flow rate at the faucet will not be enough to pour you a glass of water. 

But, none of this would happen in the Waterdrop WD-G3 purifier. If the water pressure is low, the pump will produce enough pressure head, so you get water in a few seconds.

In addition to all these, the product has a built-in TDS sensor to check your water quality. Also, you will find a filter life indicator. All these consist of electronic circuits.

How often should replace the cartridges of the Waterdrop WD-G3 RO filter?

Now, let’s talk about the maintenance of your Waterdrop WD-G3 Water purifier. 

Like all the RO purifiers, you will need to change the cartridges from time to time.  That’s because the filters get jammed after working for a certain period.

For example, the first activated carbon filter will perform well for one year at a stretch. After that, it will lose some functionalities.

As a result, the TDS level might go up, and the filter might not be able to get rid of all the pollutants. 

Similarly, the pre-sediment filter and reverse osmosis membrane can last for six months and two years, respectively.

You see, the maintenance schedule can be hectic to remember. Don’t worry. There are indicators to remind you when it’s time to change the filters.

Initially, you can take a look at the indicator on the faucet. It will change color when the time comes to change any of the three filters.

Then, you should take a look at the individual filter life indicator to identify which one is running out.

To reduce your hassle, we’ve compiled a table showing you the replacement filters of the Waterdrop WD-G3 RO water filter. Take a look.
