How we compare a system

  1. We compare systems head-to-head — filtration stages, contaminant coverage, flow rate, filter life, and price, in one table.
  2. We check the certifications — every contaminant claim is verified against NSF International listings. No lab coats, no fake testing, and we say so.
  3. We read the fine print — warranty terms, installation requirements, maintenance schedules, and replacement filter costs, in plain English.
