Waterdrop Reverse Osmosis G2 vs G3: Special Features and Benefits
Both models share similar features and offer some of the same benefits. Here are some of them:
400GPD
Both G2 and G3 purify 400 Gallons Per Day. That’s .28 GPM (gallons per minute). This allows you to get immediate filtration. They can purify one cup of water in 12 seconds. Waterdrop RO filters faster and at a consistent rate. Meanwhile, other filtration systems have a fast flow only within the first 2 minutes.
Drain Ratio of 1:1
Both models of water purifiers conserve water. All reverse osmosis water purifiers produce concentrated water to discharge impurities. Each produce less concentrated water than regular RO filters. This saves you 300% more water.
Easy Installation and Quick Filter Change
Similar to the Waterdrop WD-FC-01 NSF model, you may find the same Waterdrop design in Waterdrop reverse osmosis G3 and G2. You can install any of these units at 30 minutes or less. You don’t need any special tools to set up this Waterdrop RO filtering system. The water filter replacement only takes 3 seconds. You just twist-and-pull. Then, replace it with a new one.
Filter Life Monitoring
Take the guesswork out of filter replacements. Both models have easy filter life monitoring.
G3’s Smart Designer Faucet feature color codes. Blue means optimum filtration. Yellow means you have to replace it soon, within 15 days ideally. And, red means you should replace it immediately.
With G2’s Smart Filter Reminder, Blue light means optimum quality. Purple means replace soon. And, red means replace now.
Tankless Design
Both feature a no-tank design. This prevents bacteria growth and avoids re-contamination. G3’s tankless build saves 50% under-sink space while G2’s build saves 70% under-sink space. This gives you more storage space for other kitchen aids.
Safety Features (Sound Reminders)
Both products use special protection technology. They use insulated materials. They have integrated waterways. So there’s no risk of leakage.
There’s a booster pump overworked reminder. You will hear a beep for 3 minutes straight when the unit has been working for 30 minutes continuously. Water filtering will stop and the power will turn off.
Another reminder will warn you when the booster pump frequently starts and stops within 20 minutes. You will hear a beep 5 times. Then, both filtering indicator light and the power indicator light will turn off.
What Are Some Differences Between Waterdrop G2 and G3?
To help you decide which model is right for you, we give you this list of differences between G2 and G3 Reverse Osmosis water filters.
