## Why we chose it

The Capella RC250 earns its place over the iSpring for buyers who want the WQA Gold Seal applied to the full P473 PFAS certification in an RO system, and a compact tankless design that fits in tighter under-sink spaces. NSF/ANSI 58 (RO), 42, 53, 401 (emerging contaminants), and P473 (PFAS) are all independently certified by WQA, not just claimed. The $99/yr filter cost sits between the Coral UC300 and the Claryum. Brondell publishes specific filter change volumes rather than just annual guidelines.
