Frizzlife SK99
Score: 88/100Rankings

The Frizzlife SK99 NEW is a highly rated, NSF-certified under-sink filter that offers a direct-connect installation and a high 2 GPM flow rate. It excels in contaminant removal, including PFAS and lead, while retaining beneficial minerals. The main limitations are its sensitivity to water hardness and temperature, and it does not reduce TDS. It is ideal for families seeking premium protection without renovation costs.

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.
