The APEC Water Systems Essence ROES-PH75 is a premier 6-stage under-sink reverse osmosis drinking water filter engineered in the USA. Designed with top-tier 100% US-made filtration media, it removes up to 99% of contaminants—including lead, chlorine, fluoride, arsenic, heavy metals, bacteria, and TDS—while enriching purified water with wholesome calcium carbonate to raise pH to a healthy 8.5–9.0 alkaline balance. Features a lead-free brushed nickel designer faucet, 4-gallon storage tank, and quick-connect push-in fittings.
6-Stage Complete Purification: High-capacity sediment, dual carbon blocks, 75 GPD RO membrane, continuous alkaline remineralization, and TCR coconut shell polishing filter. Mineral Remineralization Stage: Infuses purified water with essential dietary calcium minerals, balancing pH to 8.5–9.0 and restoring crisp, natural flavor.
WQA Gold Seal Certified Media: Tested and verified against NSF/ANSI standards for structural integrity, contaminant reduction, and chemical safety. Designer Lead-Free Faucet: Heavy-duty solid metal brushed nickel high-arc faucet included with 360° swivel spout and drip-free ceramic disc cartridge.
Leak-Stop Push-Connect Fittings: Precision John Guest quick-connect fittings ensure secure, vibration-proof connections without needing special plumbing tools.

Contact usPre-filters (Stages 1–3) are changed every 6 to 12 months. The 6th stage alkaline mineral filter and TCR post-carbon filter last 12 months, and the central 75 GPD RO membrane lasts 2 to 3 years depending on local municipal water hardness.
Yes. You can run 1/4" tubing from the post-carbon tee to your refrigerator ice maker and water dispenser for crystal-clear ice and chilled alkaline water.
Standard household water pressure between 40 and 85 PSI is required. If your incoming water pressure is under 40 PSI, an auxiliary booster pump is recommended.
No. The ROES-PH75 operates entirely on household mechanical water line pressure without electricity, eliminating motor hum and electric standby power consumption.
The system operates at a standard high-efficiency 3:1 ratio under average household water pressure, significantly lower than older legacy RO machines.
