How to choose
UV stage and stage counts
A UV stage sits after the RO membrane: the iSpring, Bluevua, APEC, ecoviva and Geekpure each state a UV filter or UV light. Stage counts run from 6 to 9: the Geekpure has 6 stages, the iSpring, Bluevua and APEC have 7 stages each, and the ecoviva has 9 stages. Compare UV and stage count together, and check the GPD rating separately.
GPD, tanks and countertops
GPD means gallons per day: the iSpring is rated at 200 GPD, and the APEC and Geekpure at 75 GPD each. Tank systems store filtered water, while countertop units like the Bluevua and ecoviva sit on the counter with a carafe or pitcher. Under-sink units need space below the sink, while countertop units need counter space and an outlet.
Remineralization and warranties
Remineralization adds minerals back after filtration: the iSpring, Bluevua, APEC and ecoviva each state remineralization or an alkaline stage. Warranties differ: the ecoviva carries a 5-year warranty and the Geekpure a 1-year manufacturer warranty. Check the warranty term and the filter life together before choosing.
