Who should buy which
Buyers who rank independent certification first, preparedness households that want water with no plumbing or power, and Berkey owners who need compatible replacement elements.
You want RO-level dissolved-solids removal or on-demand flow from a tap, where an undersink system like the $329.45 RKIN Flash is the better tool for the job.
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.
