How we checked
The APEC manufacturer page (apecwater.com/products/roes-50, SKU ROES-50) confirmed the exact model — "ROES-50 - Essence 5-stage 50 GPD Reverse Osmosis Water System" — and provided the US price ("Sale price $230.99 USD"), 5-stage count, 50 GPD @ 60 psi capacity, a 4-gallon tank, WQA certification, and line-pressure operation (40-85 psi feed, no pump). The Amazon retailer page corroborated model identity (Model Name/Number/Part Number all "ROES-50", brand APEC WATER, "Essence Series Top Tier 5-Stage") plus under-sink install type and "NSF Certified 372 & 58"; its comparison table explicitly marks the ROES-50 column "pH Enhancement ✘" (no remineralization). pure-to-drain ratio, a TDS-specific reduction percent, a single membrane-life figure, and an annual filter cost in USD were not stated for this model on either page, so those are left blank.
