Who should buy which
Homeowners who have run a Tap Score test (or know their municipal water has flagged contaminants) and want to fix the upstream water-quality layer with a permanent RO installation. Also buyers maintaining existing RO systems who need replacement filters at competitive prices.
You are renting and cannot install under-sink hardware (countertop systems work but produce limited volume). Or you have not yet tested your water and might find a $50 carbon pitcher solves your specific contaminant profile.
Homeowners on chlorinated municipal or hard well water who want filtered water at every tap - shower, skin, hair, laundry - not just the drinking glass. Pairs cleanly with an under-sink RO for drinking water to cover both the point-of-entry and point-of-use layers.
You are renting and cannot plumb the main water line (an under-sink RO is the right tier for you instead). Or you only care about drinking-water quality - a point-of-use RO is cheaper and sufficient for that single job.
