Editorial judgments for Treated city water with free-chlorine taste; 6 GPM example peak demand; five-year ownership. These are not lab scores or customer ratings. A missing fact stays unscored; we do not fill it in with a guess.
- Treatment evidence Meets the brief
- Maker lists chlorine/chloramine treatment. We do not treat its broad chemical claims as a certified health-contaminant guarantee.Source
- Water and size fit Meets the brief
- CF1 is 9 GPM and 25–80 psi in both documents. The CF4 disagreement prevents extending that assessment to all sizes.SourceCompare document
- Setup Meets the brief
- Main-line installation, tank space and prefilter access. Include isolation/bypass plumbing in the quote.SourceCompare document
- Upkeep Needs confirmation
- Prefilter is listed at 6–9 months. Sales page says 10 years/1 million gallons for media; linked manual says 6 years/1 million.SourceCompare document
- Long-term cost Needs confirmation
- Five-year cost needs the selected tank, installation, prefilters and any media work. Conflicting service documents prevent a reliable long-term total.SourceCompare document
- Warranty and returns Tradeoff
- Detailed terms limit general returns to unused/uninstalled systems and apply fees. Installed returns require a defect determination; this is not a free installed trial.Source
Unresolved maker-document differences: 10 versus 6 years of media life, and CF4 12 versus 11 GPM. No overall rank until resolved.
Checked . Assessment applies to CF1 baseline; CF4/CF+ are different sizes.
