ROES-PH75 6-Stage Alkaline RO System

Score: 8.6/10 | The APEC ROES-PH75 solves the "RO removes everything" problem by adding a sixth stage that restores beneficial minerals and raises pH to alkaline levels. With over 10,000 five-star reviews, WQA certification, and US-based lifetime support, this is the RO system I recommend for families who want pure water without the flat taste and mineral concerns.

This review uses R3's Water Filter Methodology v1.1.0.

The Water Quality Association has tested and certified the ROES-PH75 for contaminant removal. WQA certification ensures the system meets industry standards with third-party verification.

1. Stage 1 - Sediment Filter: Removes particles, dust, rust
2. Stage 2 - Carbon Block: Removes chlorine, taste, odor
3. Stage 3 - Carbon Block: Additional chemical removal
4. Stage 4 - RO Membrane: 99% TDS removal including lead, arsenic, fluoride
5. Stage 5 - Coconut Carbon Post-Filter: Final polish for pure taste
6. Stage 6 - Alkaline Remineralization: Adds calcium and magnesium, raises pH

Standard RO effectiveness:

• Total dissolved solids (TDS): 99%
• Lead: 99%
• Arsenic: 99%
• Fluoride: 95%+
• Chromium 6: 99%
• Bacteria and viruses: 99%+

APEC assembles systems in California with US and imported components. This provides quality control advantages and supports domestic manufacturing.

75 gallons per day production exceeds most families' drinking water needs. The 4-gallon storage tank ensures ample supply for cooking and filling water bottles.

The sixth stage passes RO-purified water through natural mineral stones containing calcium and magnesium. This:

• Raises pH from acidic (~6) to alkaline (~7.5-8.5)
• Adds back beneficial minerals
• Improves taste compared to pure RO water

The "flat" taste common to RO water is eliminated while maintaining purity.

• Pre-filters: 6-12 months
• RO membrane: 2-3 years
• Post-filter and alkaline: 2-3 years

Annual filter cost is relatively low given stage count.

The included lead-free chrome faucet provides a dedicated clean water tap. Installation requires drilling a hole in the sink or countertop.

Excellent value for a 6-stage system:

• Budget 5-stage RO: $150-200
• APEC ROES-PH75 6-stage alkaline: $299
• Premium tankless RO: $400-600

The alkaline stage addition costs approximately $50-75 over basic systems.

• Pre-filter set (3 filters): $50-60 annually
• RO membrane: $50 every 2-3 years
• Post-filter + alkaline: $30 every 2-3 years

Annual average: approximately $70-90

APEC provides free lifetime phone support from US-based technicians - a significant value for complex systems. Call with installation questions, troubleshooting, or maintenance guidance anytime.

Double the typical 1-year RO warranty, with the option to extend.

6-stage systems have more components than basic RO. Plan 2-3 hours for first-time installers. APEC provides detailed video tutorials and phone support if needed.

Requires significant under-sink space for 6 filter canisters plus the 4-gallon tank. Measure carefully before purchasing.

Quick-connect fittings make filter replacement straightforward. No tools required once system is installed.

The ROES-PH75 uses traditional RO technology with approximately 3:1 waste ratio. Less efficient than the Brondell Circle (1:1) but standard for the price point.

APEC suggests collecting waste water for non-drinking uses. Many families connect the drain line to irrigation or use buckets for cleaning.

The APEC ROES-PH75 is the best value alkaline RO system for families wanting pure water without the mineral loss and flat taste of standard RO. The 6-stage design with remineralization addresses RO's primary criticism while maintaining 99% contaminant removal. With lifetime US support and a 2-year warranty, this is a confidence-inspiring purchase for families new to RO filtration.

If water efficiency is your priority, consider the Brondell Circle despite its higher price. For budget-only consideration, basic 5-stage APEC systems start around $200.
