Who should buy which
Renters, dorm dwellers, and RV owners who want genuine reverse osmosis with zero plumbing and the filter budget settled for roughly three years upfront.
You want hot and cold dispensing or app monitoring, where RKIN's own U1-W at $749 is the step up, or you buy strictly on independently confirmed certification listings.
Renters and small households who want true reverse osmosis with hot and cold dispensing and zero plumbing, and who accept brand-stated (unpublished) test results in place of NSF certification.
You want NSF-certified reduction claims (Boroux leads there), you need high-volume water for a large family, or wastewater bothers you (RO discards roughly half of each fill).
