Absolutely as described by the manufacturer! Great system
I own a custom home construction company near Cleveland Ohio. Cleveland City water has a 7 ppm hardness which is really pretty mild. However just the 7 ppm etches glass and leaves hard water spots on tile and sinks over time. We installed Springwells large home system recently. It included a large carbon tank / filter to pre treat the city water and a large media filter that removes the hard water. The system is smart and uses only the salt wash needed. So far this system, after 3 months use has used 1 bag of salt. The smart software is really helpful for programming and monitoring the system usage.
Oh, one other thing about Springwell system is they do not affect water pressure or volume when size AND INSTALLED correctly. This system is quite remarkable for the price.
