Review on ISpring RCC100P High Capacity 5-Stage Under Sink Water Filter Reverse Osmosis RO Drinking Water Filtration System, 100 GPD, Performance-Boosted by Julpikz Bellemy

The unit was easier to install than I expected. I had to drill a hole in the one inch thick granite counter top for the spigot and made a small stand from scrap lumber to make it easier to position and maintain. Other than those two items, it is pretty much plug and play to install and start-up. It did arrive with one of the filters damaged during shipping but that was quickly rectified with a new filter after contacting the manufacturer.I checked the performance with my TDS meter and found that that 97% of the salts (TDS) were sent to the waste stream. The unit produces about 6 gallons per hour due to higher home water pressure and a clean new RO membrane. We are very happy with it so far - you can definitely taste the difference in the water.
