A. O. Smith Single-Stage
Score: 78/100Rankings

The AO Smith Single-Stage Whole House Water Filter is a low-maintenance, activated carbon system designed to reduce chlorine taste and odor with a 6-year filter life. It does not remove sediment, bacteria, or PFAS, making it unsuitable for well water with high sediment. It is best suited for households of 4 or more with city water supplies seeking to improve chlorine taste and odor.

The Culligan HF-360A is a standard-duty whole-house sediment filter designed for basic pre-filtration on 3/4-inch main water lines. Its primary limitation is the lack of chemical or lead reduction capabilities, restricting it to sediment protection. It is best suited for rural properties or homes with well water high in sand, rust, or dirt.
