WIRED compares three stainless-steel, gravity-fed countertop water filters—Boroux Legacy, Culligan MaxClear and Rorra—focusing on their filtration performance, plastic exposure, ease of use and supporting certifications. The comparison reflects growing consumer concern about microplastics, particularly among people seeking alternatives to plastic water pitchers and bottled water.

Boroux is recommended as the best option for most people, while Culligan is judged the strongest overall for certified filtration performance despite slow flow rates and costly replacement filters. Rorra is presented as the most convenient, with water- and filter-level sensors, but carries the highest price; the article also notes that Boroux emerged after former Berkey distributors were affected by Berkey’s regulatory disputes.
