APEC ROES-50 Essence
1 source$182.73as of Oct 7

The APEC ROES-50 Essence is the reliable workhorse of RO systems, a WQA Gold Seal NSF/ANSI 58 certified 5-stage unit that TechGearLab scored 94 out of 100, the highest tested score in this roundup. Lab testing brought every critical contaminant, lead, arsenic, uranium, PFNA, to undetectable levels. There's no remineralization and the tank eats space. As a proven, durable, high-performing pure-RO system at a fair price, it's outstanding.

Strengths
  • — WQA Gold Seal certified to NSF/ANSI 58 for TDS reduction
  • — Reliable 5-stage filtration removing up to 99% of contaminants
  • — Proven, durable design from a long-established RO brand
Watch-outs
  • — No remineralization stage, so beneficial minerals are removed
  • — Tank takes up significant under-sink space, as TechGearLab notes
  • — Filter changes are less convenient than some rivals; RO-System.org notes swapping the housings can be a little messy

Waterdrop G3P800
Ranked #2 in Best Reverse Osmosis Systems
Waterdrop G3P800
1 source$759as of Sep 25

The Waterdrop G3P800 is a tankless 800 GPD unit that's NSF/ANSI 42, 53, 58 and 372 certified and dispenses fast with no storage tank. It posted one of the best efficiency ratios of any tankless RO tested at 3:1 pure-to-drain, and lab testing confirmed 93-95% TDS reduction. Its only real gaps are price and the missing built-in remineralization, which Waterdrop sells separately.

Strengths
  • — NSF/ANSI 42, 53, 58 and 372 certified, covering taste, health contaminants, TDS and lead-free materials
  • — Tankless 800 GPD design dispenses fast and saves under-sink space
  • — Excellent 3:1 pure-to-drain efficiency, among the best of any tankless RO tested
Watch-outs
  • — No built-in remineralization; water can taste flat without the add-on
  • — Requires electricity and a drain connection
