Score: 85/100
SimPure Y7P
Score: 88/100Rankings
The SimPure Y7P-BW is a high-efficiency countertop RO system featuring UV sterilization and a superior 4:1 water recycling ratio. While it offers fast dispensing and excellent contaminant removal, it lacks comprehensive independent certification for all claims and has a plastic build. It is best suited for renters and eco-conscious users who prioritize water savings and ease of use.
The Big Berkey is a gravity-fed countertop water filtration system constructed from surgical-grade stainless steel, designed to remove over 200 contaminants without requiring electricity. It offers a 2.25-gallon capacity suitable for small households or emergency preparedness, featuring expandable filtration options and a durable, nestable design. While praised for robust contaminant removal, the slow filtration speed and lack of official certification are notable trade-offs.
