Score: 85/100
Waterdrop TSA
Score: 82/100Rankings
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.
The Waterdrop TSA is a compact, 8-stage under-sink filtration system designed to reduce over 100 contaminants while retaining beneficial minerals. It lacks TDS reduction capabilities and is limited to cold municipal water. It is best suited for renters or DIYers wanting a quick, low-maintenance upgrade for taste and safety.
