APEC ROES-PH75 Alkaline Mineral pH+ 75 GPD Reverse Osmosis System

In this review of the APEC ROES-PH75, the bottom line is simple: this 6-stage, 75 GPD reverse osmosis system is for households that want thoroughly filtered drinking water with a mild alkaline boost and dependable long-term operation. The reviewer found the system removes a wide range of impurities while adding high-purity calcium carbonate for improved taste and alkalinity, making it a good choice for people shifting from bottled mineral water to tap-based purified water. Installation is approachable for a handy homeowner and the system feels engineered for lasting use.

Key Features

• 6-Stage Filtration: Multi-stage filtering removes chlorine, taste, odor and many contaminants so water tastes clean and is safer for everyday drinking.
• 75 GPD Capacity: Sufficient flow for most families, supplying unlimited clean drinking water without frequent filter changes under normal household use.
• Alkaline Mineral Cartridge: Adds premium-grade calcium carbonate to gently raise pH and restore pleasant, mineral-like taste without uncertain mineral sources.
• High Contaminant Removal: Designed to reduce fluoride, arsenic, lead, heavy metals and over 1000 impurities for noticeably clearer water quality.
• Durable Construction: Built with premium components intended for long service life and quiet, trouble-free operation in a home under-sink installation.
• WQA Certified: Certification gives added confidence that the system meets recognized performance and safety standards.

Who It's For

This system suits families and households who want near-complete contaminant reduction combined with a modest pH increase from a known mineral source; it is ideal for people who prefer the taste of mineral water but want it produced at home. It also fits those with tap or well water up to fairly high TDS levels who need a robust, certified unit that will run quietly and reliably.

Those who should look elsewhere include users who require higher daily output than 75 GPD for heavy commercial use, or people who want a multi-mineral remineralization blend rather than primarily calcium carbonate. Also consider professional installation if you are not comfortable with under-sink plumbing work.

Pros & Cons

Pros

• High contaminant reduction delivers noticeably improved water quality and taste.
• The premium mineral cartridge uses certified calcium carbonate to safely raise pH and enhance flavor.
• Clear instructions and pictured guides make installation approachable for many DIYers.
• WQA certification and premium components support long-term, quiet operation.

Cons

• Some users report occasional leakage issues, so careful installation and periodic checks are advisable.
• 75 GPD is adequate for most homes but may be limiting for very large households or heavy point-of-use demand.
