Waterdrop Under-Sink & Countertop Filtration WD-G3P800-W Editorial Review
The Waterdrop G3P800 Reverse Osmosis System has received positive feedback from customers who have been using it for a month or more, commenting that the installation guide was easy to follow and the taste of the water it produces was great. However, there were some negative comments regarding the noise level of the unit and some users had issues with the tubing leaving an undesirable "hose" taste. In terms of filtration performance, the TDS levels in the water were significantly reduced. It is certified by NSF/ANSI 58 and 372 and has a 3:1 pure to drain ratio. As for the differences between Waterdrop's G3P800 and KJ600 RO systems, the G3P800 can only filter cold water, whereas KJ600 can dispense hot water. More so, there are 3 filters in total for G3P800, and only one filter for KJ600. G3P800 can be connected to the refrigerator, while KJ600 cannot. However, the G3P800 is Considered expensive and the automatic flush feature is noisy and wastes 4 cups of water with each flush.
