Frizzlife PD600-TAM3 vs. Waterdrop WD-G3-W

And now, let’s dig deep into the features that distinguish the 2 products.

1. Design

Frizzlife PD600-TAM3 comes in a tankless design. It is a compact and sleek system with a small and convenient footprint that takes up less space.

Waterdrop WD-G3-W boasts a tankless design as well. It is an innovative, all-in-one intelligent water filtration system.

 It is also compact and space-saving.

The tankless design of the 2 systems helps to avoid secondary pollution and enables users to enjoy more storage space in the kitchen.

2. Drain Ratio

Thanks to advanced water-saving technology, PD600 has a super low drain ratio of 1.5:1. As a result, it maximizes the efficiency and saves water up to 450% compared to traditional RO systems.

This system is both economic and environmentally friendly. It also makes your water bills more affordable.

Waterdrop G3 has a low drain ratio as well. In fact, better than the PD600. It has pure water to waste water ratio of 1:1. Compared to conventional systems, it saves waste water by 300%.

With either of the models, you get to save on your water bills.

3. Water Flow Rate

PD600 boasts a built-in pump and can produce 600 gallons of water per day. With this high capacity, this system can serve all the daily water needs of any large family.

The unit’s water flow is fast and stable and can fill a 330ml glass of water in about 10 minutes.

And just like the PD600, the G3 boasts a built-in pump. And thanks to this pump, the RO system offers a fast water flow of 400 gallons per day. It can also filter a cup of water in about 12 seconds.

4. Filtration Performance

PD600 RO system uses a high-grade RO with 0.0001 micron filtration accuracy. It uses 3 filters to purify water with 7 filtration layers.

  • Filter 1 – Composite filter(ASR211)

This filter blocks debris and removes particles such as rust, sand, silt, and insoluble impurities. It also conditions the water and prolongs the life of the RO membrane.

  • Filter 2 – High-grade 0.0001 MRO membrane(ASR212)

The filter eliminates 99.9% of harmful contaminants in the water, including fluoride, chlorine, heavy metals, lead, mercury, VOCs, chloramine, and arsenic.

  • Filter 3 – Alkaline remineralization filter(TAM3)

The filter restores all essential minerals to the water, balances the alkalinity of the water, and adjusts it PH to around 7.5. It removes odor, bad taste and polishes the flavor of your water.

Just like with the PD600, Waterdrop G3 uses 3 filters in a 7-stage filtration process to purify your water. However, unlike the PD600, it doesn’t have a remineralization stage.

The filters include

  • Pre sediment and carbon block filter

This is a 3 in 1 filter that functions as 3 filters combined. It removes large particles from the water, including salt, sand, rust, and other chemicals that can affect the taste of the water. It can actually intercept over 1,000 contaminants.

  • RO membrane filter

This filter is probably more efficient in this system than any other. Reason. It’s very large with a height of 15” and 4.3” across. It filters water effectively with the help of the built-in pump that prevents backflow.

  • Activated carbon block filter

This filter is made from natural coconut shells and returns the beneficial minerals to the water. This helps to minimize the acidity of the water, remove odor and enhance the taste.

5. Smart Features

PD600 boasts a smart TDS meter located on the front faceplate. This meter measures all particles present in your water. The meter also notifies you when the filters are due for replacement.

Waterdrop G3, on the other hand, boasts a smart pressure pump that detects the pressure of incoming water and adjusts appropriately. It also has a smart lead-free faucet with an LED light that turns on when in use.

6. Safety Features

Waterdrop G3 boasts several safety features. For instance, if the system works continuously for over 2 hours, the surface of the RO membrane gets flushed automatically for 20 seconds. Likewise, where the machine fails to dispense water for 24 hours, the system is automatically flushed for 1 minute to inhibit breeding.

In case of a leak, the buzzer keeps beeping until the malfunction is rectified. Also, to extend the pump’s lifetime, the malfunction buzzer beeps for 3 minutes if the system keeps dispensing water for over 30 minutes. If over 33 minutes, it automatically stops dispensing the water.

There’s also corresponding protection if your machine is frequently started and stopped by an improper operation. In case of such a malfunction, the buzzer beeps 5 times. After that, it automatically stops dispensing water.

Such safety features aren’t available with Frizzlife PD600.

7. Installation and Maintenance

Both systems are quite easy to install and maintain. With general DIY skills, you can put the PD600 in less than an hour. The package also comes with extras that make the installation process pretty easy.

As aforementioned, installing the Waterdrop G3 is also a breeze. Actually, this system comes partially assembled, and putting up the rest should take you less than an hour.

After installation, you need to flush the G3 with water for 30 minutes. And since the flushed water isn’t suitable for drinking, you can use it for other purposes like watering plants.

Both systems are also easy to maintain. Since they’re tankless, cleaning and additional sanitization may be unnecessary. All you should do is replace the filters when due, usually after 6 months, a year, or 2 years.

8. Certifications

Waterdrop G3 is NSF 372 for lead-free material and NSF 58 certified for TDS reduction. It has also passed 400+ chemical lab tests proving that it doesn’t contain 400+ chemical substances.

There are no certifications for Frizzlife PD600 as of now.
