Excellent water filter. I did a fair amount of research and ended up buying the G2 P600 tankless RO system from Waterdrop. Couldn’t be more pleased with my decision. Quality is of the highest order, from packaging to product to instructions. If Apple made water filters they would be be Waterdrop. Our municipal water has a TDS of around 340, with a distinct unpleasant odor, and it doesn’t taste so good. After filtering, there’s a night and day difference in taste, and no odor (I don’t have a TDS meter so I can’t provide that data point). Simply amazing! I tested the flow rate and get 0.51 gal/min, higher than the advertised rate of 0.42 gal/min (our water pressure is about 82 psi). I’ve even noticed the scale buildup in my electric hot water pot is gone after using filtered water for a month. Buy, you won’t be disappointed.
