Specs & FAQs
Quick reference specifications and answers for this product.
The RO stages purify the water first. A separate finishing stage then adds selected minerals back and adjusts the finished water toward a pH 7.5+ profile.
The system is rated at 1000 GPD / 0.69 GPM for direct-flow RO water.
The RO filter is rated for up to 3 years and the PCF filter for up to 1 year under stated conditions. Actual life depends on source-water quality and household use.
The Electrolux app lets you review TDS, water use and filter-life information.
Measure the available cabinet space, pipes, outlet and tubing clearance before purchase. The tankless body is 5.2 inches wide.
