Alkaline remineralization filter(TAM): This filter restores natural minerals lost during the filtration process, balances the alkalinity of the water and adjusts PH to more than 7.5. It also helps to reduce bad taste and odor.

On the other hand , Waterdrop G3 also filters water in 7 stages. It uses 3 filters as well filters but unfortunately, no remineralization filter to restore the lost essential minerals.

The filters include of G3 Waterdrop:

The pre-sediment and carbon-block filter: This is a 3 in 1 filter that functions as 3 filters combined. It’s responsible for removing large particles such as salt, sand, silt and other chemicals that interfere with the taste of your water.

RO membrane filter: The RO filter comes in an innovative design, and its efficiency equals more than 3 stages of filtration. It’s also extensive, with a height of 15 inches and 4.3 inches across.

Activated carbon block filter: This filter aims to return the beneficial minerals to your water. It also helps to minimize the acidity of the water and improve the taste.

  • Water Flow Rate

Water flow is fast and stable, and the unit can fill a 330ml cup in about 10 seconds.

The G3, on the other hand, produces 400 gallons of water per day and can filter a glass of water in 12 seconds. Since it produces water fast, the system can meet the needs of your entire family or a small company.

  • Drain Ratio

PD600 uses an advanced water-saving technology that maximizes its efficiency. It has a low drain ratio of 1.5:1 and can save your water by up to 450% compared with conventional RO systems.

It is both economical and environmental-friendly and can make your water bills more affordable.

The G3 has a super low drain ratio of 1:1 and saves water waste by 300%. With this system, you’ll cut on your water bills as well. Over the life of this system, the Waterdrop G3 filter pays for itself in water savings.

  • Smart Features

  • System Protection Features

The Waterdrop model comes with several protection features that ensure that your unit stays in good shape for the longest time possible.

It has a built-in leakage protection system that notifies you with a buzzer in case of water leaks. And to rectify this problem, all you need to do is pull out a water container, clean it and reinstall it back.

To extend the pump’s life and reduce all risks caused by forgetting to close the faucet, the unit alerts and malfunction indicate E03. The buzzer will also beep for 3 minutes if the faucet keeps dispensing water for over 30 minutes. If it exceeds 33 minutes, it will automatically stop.

Also, there’s corresponding protection where the system is frequently started and stopped by improper operation. If this happens, the malfunction indicates E04, the buzzer beeps five times, alerts and automatically stops dispensing water.

Such features are not there in Frizzlife PD 600.

  • Automatic Flushing

If the G3 works accumulatively for over 2 hours, the surface of the reverse osmosis membrane gets flushed automatically for 20 seconds. And should the unit stop dispensing water for 24 hours (goes on holiday mode), the system is automatically flushed for 1 minute.

Flushing the system helps prevent breeding and ensure that your water remains fresh and safe at all times.

There’s no automatic flushing in PD 600.
