Overview

APEC Essence ROES-PH75 6-Stage Under-Sink Alkaline Reverse Osmosis System

Engineered and tested in the USA, the APEC Essence ROES-PH75 combines laboratory-grade 6-stage reverse osmosis purification with natural alkaline remineralization. Unlike conventional reverse osmosis units that leave water slightly acidic and stripped of all minerals, the ROES-PH75 utilizes food-grade calcium carbonate in its sixth stage to enhance water alkalinity to a healthy pH of 8.5–9.0, producing crisp, refreshing, mountain-spring quality drinking water right at your kitchen sink. The system eliminates up to 99% of over 1,000 hazardous contaminants—including lead, chlorine, fluoride, toxic heavy metals, arsenic, nitrates, microplastics, and total dissolved solids (TDS). Complete with quick-connect JG push-in fittings, color-coded food-grade tubing, a 4-gallon pressurized storage reservoir, and a solid lead-free brushed nickel designer faucet, it delivers effortless DIY installation and years of trouble-free domestic operation.

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.

TDS dropped from 380 down to 14 ppm — pure bottled quality

Our municipal tap water here in Arizona has a strong mineral and chlorine bite. Installed the Apec Roes Ph75 Essence Reverse Osmosis System under our kitchen sink in about an hour and a half. The quick-connect fittings made plumbing straightforward with zero leaks. Flow rate from the dedicated faucet is strong and fills a large glass in seconds. Tea, coffee, and ice taste completely pure now.

Tankless design saves so much under-sink storage space

Replaced an old bulky tank system with this Apec Roes Ph75 Essence Reverse Osmosis System. Having full access to our cleaning supplies under the sink again is fantastic. The real-time filter life indicator is very convenient, and the water tastes noticeably crisper than standard pitcher filters.

Packaged securely, fast delivery and crystal clear ice cubes

Arrived in double-boxed commercial packaging with all adapters and color-coded tubing included. Hooked it to both the sink faucet and our refrigerator ice maker. Ice cubes are crystal clear and there is no plastic aftertaste.

Questions and answers

Can’t find what you need? Send us a message and we’ll get back to you.

How often do the filters need to be replaced?

Pre-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.

Can this system connect to my refrigerator or ice maker?

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.

What water pressure is required to operate?

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.

Does this system require an electrical outlet?

No. The ROES-PH75 operates entirely on household mechanical water line pressure without electricity, eliminating motor hum and electric standby power consumption.

How much waste water does the system produce?

The system operates at a standard high-efficiency 3:1 ratio under average household water pressure, significantly lower than older legacy RO machines.

What is the return and warranty coverage?

Groundmark provides a 30-day money-back guarantee, free residential delivery, and a 1-year manufacturer warranty with lifetime US customer service.

How does delivery work?

Delivery is free to residential addresses. Orders ship from our Dallas, TX warehouse, and larger items arrive by freight with a liftgate drop at your curb or driveway. You get a tracking number by email as soon as the carrier picks up your order.
