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.
Emergency preparedness, off-grid living, and travel where grid water cannot be trusted and you need true virus-level purification, not just bacteria filtration.
You need a continuous high-flow household supply, an NSF/ANSI-numbered certification on paper, or an ultralight backpacking filter (the Sagan XStream straw is the lighter pick there).
