Score: 85/100Rankings
The APEC RO-PH90 is a robust 6-stage reverse osmosis system designed to remove over 1,000 impurities while remineralizing water for a natural spring-like taste. Its primary trade-off is a high waste water ratio of 3:1, which is typical for classic RO systems. It is best suited for households seeking high-quality, mineral-enhanced drinking water and are willing to manage maintenance.
The Express Water ROALK is a 10-stage reverse osmosis system that combines high-capacity filtration with alkaline remineralization to produce high-quality drinking water. Its main limitations are a very slow flow rate and a larger physical footprint that requires careful cabinet space planning. It is best suited for families seeking comprehensive contaminant removal and mineral enhancement with a DIY installation approach.
