Who should buy which
Renters who can't plumb under-sink, buyers skeptical of RO mineral stripping, families wanting a redundant power-off-resilient system, anyone outside the US where municipal water has heavy chlorination but acceptable mineral content.
Your tap water has tested high for nitrates, total dissolved solids over 500 ppm, or persistent heavy-metal contamination above EPA action levels, those scenarios actually warrant RO, not ceramic.
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.
