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.
Preparedness-minded buyers, travelers, RV and off-grid users, and anyone who wants a power-free, plumbing-free way to make almost any freshwater source drinkable when the tap is unavailable or unsafe.
Your only concern is everyday home drinking water from a working municipal tap: a permanent under-sink RO or whole-house filter is the right tier for that, and the AquaBrick does not treat saltwater.
