Clear Carafe: Water Filters by Problem

Field notes

The homepage uses a symptom-to-cause-to-filtration workflow rather than beginning with product categories. Its comparisons include practical constraints such as drilling, wastewater, available space, annual media changes, and grains per gallon. The site reports zero in-house units tested and instead describes a source-based process built from certification listings, manufacturer performance sheets, EPA and NSF standards, and cost-per-gallon calculations.
