The APEC ROCT-A1000ALK is APEC’s flagship tankless reverse osmosis system with built-in alkaline remineralization — combining premium RO water quality with the alkaline mineral profile that many drinking water enthusiasts prefer. The alkaline pH+ stage adds calcium, magnesium, and potassium minerals back into the purified water after RO removal, producing finished water with a pH around 8.0-9.0 instead of the slightly acidic pH that pure RO water typically delivers.
NSF 372 and 58 certified by IAPMO for filtration effectiveness across more than 1,000 impurities including TDS, Lead, Arsenic, Radium, Chlorine, Chromium, PFAS/PFOS, and pharmaceutical residues. The 2:1 pure-to-drain water ratio is significantly more efficient than competing RO systems (typical RO is 3:1 or 4:1 waste-to-pure), meaning less water wasted to drain. 1,000 GPD capacity fills a 16 oz cup in under 6 seconds — fast enough for normal household use without the lag traditional RO systems impose.
The compact tankless design with front-facing filter housings means quick cartridge changes without contorting under the sink. For premium-drinking-water households who want both RO purity and alkaline mineralization in a single system, this is the top-of-line option. APEC Water Systems is designed, engineered, and assembled in the USA at their California facility.
