APEC Water ROES-PH75 Essence Series (Alkaline Mineral pH+, 75 GPD, 6-Stage)

How does the alkaline mineral enhancement work?

The 6th stage uses a premium calcium carbonate filter that adds back beneficial minerals after the reverse osmosis process. Unlike other systems that use unknown mineral sources, this system specifically adds high-purity calcium carbonate from trusted sources. This raises the water's pH to create naturally alkaline water whilst improving taste and providing a smooth, fresh texture that enhances beverages.

What contaminants does this system remove?

The system removes up to 99% of contaminants including chlorine, taste, odour, fluoride, arsenic, lead, chromium, radium, heavy metals and over 1000 other impurities. The high-rejection TFC membrane effectively reduces total dissolved solids up to 2000 PPM. It also removes sediment, rust, particles and volatile organic compounds through its multi-stage filtration process.

How much water does it produce daily?

The system produces 75 gallons per day (GPD) of purified water, which is sufficient for average household drinking and cooking needs. The actual production rate depends on water pressure (requires 40-85 PSI), temperature (40-100°F) and incoming water quality. The included storage tank ensures you have clean water available on demand.

What maintenance is required and how often?

Replace stages 1-3 (sediment and carbon filters) every 6-12 months depending on water quality and usage. The RO membrane (stage 4) typically lasts 2-3 years, whilst the post-carbon and alkaline filters (stages 5-6) need replacing every 12 months. The system uses standard 10" x 2.5" filters that are widely available and cost-effective to maintain.

Is professional installation required?

No, the system includes comprehensive instructions and all necessary tools for DIY installation. Most homeowners can complete installation in 2-3 hours. You'll need basic tools and skills to connect to your cold water supply, install the drain saddle, mount the system under your sink and drill a hole for the dedicated faucet. Professional installation is available if preferred.

Will this system work with well water?

Yes, the system effectively treats both tap and well water. However, well water should be tested first as it may contain higher levels of sediment, iron or bacteria that could require pre-treatment or more frequent filter changes. The system handles up to 2000 PPM total dissolved solids, but extremely hard water may reduce filter life and require additional pre-filtration.

How much space is needed under the sink?

The system measures 40.6cm length x 13.3cm width x 45.7cm height and weighs 12.2kg when empty. You'll need adequate space for the main unit plus the 3.2-gallon storage tank. Most standard kitchen cabinets accommodate the system, but measure your space first. The compact design fits most under-sink installations whilst leaving room for other items.

What certifications does this system have?

The system holds WQA Gold Seal certification and meets NSF/ANSI 58 standards for reverse osmosis drinking water treatment systems. These certifications verify the system's contaminant removal claims and ensure it meets strict safety and performance standards. APEC is America's number one rated water filter brand with 20 years of proven expertise in reverse osmosis technology.
