I live in branchburg and looking to install a water Softner although Costco gave a quote of $6k and ultra pure gave a quote of $4250, wondering if those selling whole systems for around 1500 are good enough?

Both of these packages included, a whole house filter and a RO system at the water sink in kitchen. Have a hardness of 9, CL of 0.9, and most of the companies recommended a carbon filter is that needed of chlorine is only 0.9?
