Big Berkey 2.25 Gallon
Score: 85/100
Culligan MaxClear Countertop Water Filter
Score: 78/100Rankings
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.
The Culligan MaxClear is a premium gravity-fed countertop water filter distinguished by its unique triple certification for microplastics, lead, and PFAS reduction. Its primary trade-off is an extremely slow filtration rate, requiring up to 8 hours to fill the 3-gallon capacity. It is best suited for health-conscious users who prioritize certified contaminant removal over speed and are willing to pay a premium for durable stainless steel construction.

Professional reviewers and editors praise the Big Berkey for its robust contaminant removal capabilities, noting that it exceeds NSF/ANSI Standard 53 in laboratory settings. Experts highlight its durable stainless steel build and versatility for various water sources. However, they criticize the slow filtration flow rates and the lack of official NSF certification for the complete system.
Everyday users generally praise the Big Berkey for its reliability, long filter life, and ability to purify water without electricity, making it a favorite for families and emergency preparedness. Common recurring complaints include the slow filtration speed, which can take over two hours to fill, and the hassle involved in priming the filters.
Choose MaxClear for certified contaminant reduction and compatibility with existing gravity systems; choose Berkey if standalone gravity filtration is preferred.
Professional reviewers give the MaxClear an overall score of 8.55 out of 10, praising its superior filtration media quality and unique triple certification. Experts consistently identify the 0.3 GPH filtration rate as the primary limitation.
Users who prioritize certified contaminant reduction accept the slow filtration rate as a necessary trade-off, while those seeking faster water availability may find the system impractical.
