Comparing Waterdrop D6 and G3

Waterdrop is well-known in the water treatment industry for its impressive range of modern, space-saving, forward-thinking countertop and under-sink reverse osmosis systems.

Two of Waterdrop’s most popular products are the Waterdrop D6 and the Waterdrop G3.

In this guide, we’ve compared these water purification systems, discussing their features, pricing, benefits, and setbacks, to help you decide which (if any) is best for you.

The Waterdrop D6 is a 600 GPD under-sink RO system that uses 6 stages of filtration to purify tap water.

The Waterdrop G3 is a 400 GPD under-rink RO system that purifies tap water with 8 stages of filtration.

The Watdrop D6 can remove “most pollutants”, including chlorine, lead, nitrates, benzene, PFAS, chromium, and more.

What Contaminants Do They Remove?

Waterdrop doesn’t give an estimated TDS reduction for this system, which is a shame, because it does tell us that (based on testing) the Waterdrop G3 has an average TDS reduction rate of 91.9%.

The biggest performance benefit of the D6 is that it has a faster flow rate than the G3, so you can fill a glass of filtered water around 4 seconds faster.
