Score: 85/100Rankings

The Aquasana AQ-5300.55 is a 3-stage under-sink filter using Claryum technology to remove 99.99% of contaminants while retaining beneficial minerals. It is certified to multiple NSF/ANSI standards and offers a significantly faster flow rate than pitcher filters. It is best suited for households seeking rigorous contaminant reduction without the complexity of reverse osmosis.

The Frizzlife MK99 is a compact, NSF-certified under-sink filter that offers rapid installation and replacement with a high 2.0 GPM flow rate. It effectively removes lead, chlorine, and heavy metals while retaining beneficial minerals. Its main limitation is the inability to remove bacteria or viruses, making it less comprehensive than RO systems. It is best suited for households seeking affordable, easy-to-maintain filtration.
