Who should buy which
Homeowners who want filtered water at every tap, care about shower and bathing water as much as drinking water, and are willing to do a point-of-entry install for whole-home coverage.
You rent, cannot plumb a point-of-entry system, or only want to improve drinking water, in which case a countertop or under-sink filter is the right scope.
Households on municipal water who specifically want whole-house lead, cyst, and PFOA/PFOS reduction with published paperwork behind the claims, and who will pay the specialist premium.
You mainly want chlorine, taste, and scale handled, where the Kind E-3000 at $2,094.10 covers the job for less, or your home's peak demand outruns 4.52 GPM service flow and the 4+ bathroom pricing stings.
