APEC Water Systems 10ft High Purity PH+ Calcium Carbonate Alkaline

In this review of the APEC Water Systems 10' High Purity PH+ Calcium Carbonate Alkaline Filter, the bottom line is straightforward: this is a targeted add-on for reverse osmosis systems designed to raise and stabilize water pH by adding calcium carbonate back into the water. It is best for homeowners who already have an RO system and want an uncomplicated, mineral-based way to neutralize acidity and improve taste. Installation is meant to be quick and leak-free, and the filter's construction focuses on purity and a reliable seal.

Key Features

• pH improvement: Adds high purity calcium carbonate to raise and stabilize water pH for less acidic, more palatable drinking water.
• US-made media: Uses 100% US-made high purity calcium carbonate to reduce impurities and maintain consistent mineral quality.
• Solid construction: Friction-welded housing avoids glues or binders so the filter aims to provide a durable, no-leak seal under normal conditions.
• Quick connect fittings: Includes 1/4 in quick connection fittings intended to make installation fast and minimize the need for special tools.
• RO compatibility: Designed as an add-on for existing or new reverse osmosis drinking water systems so it integrates with most standard setups.

Who It's For

This filter is a good choice for RO system owners who want to restore a small amount of natural minerals and raise pH without switching to a completely different filtration approach. It suits homeowners focused on taste improvement and mild alkalinity rather than heavy remineralization.

Those needing large changes in water chemistry, precise pH control for aquarium use, or a multi-mineral remineralization stage should look elsewhere. Also, buyers who must avoid any risk of connector issues should be prepared to check fittings and seals during installation.

Pros & Cons

Pros

• Improves flavor by adding calcium carbonate, delivering a cleaner, more refreshing taste for many users.
• Uses 100% US-made high purity media, which supports consistent performance and fewer impurities in the added mineral.
• Friction-welded construction aims to eliminate glues and binders, reducing potential sources of leaks or contamination.
• Quick connect 1/4 in fittings make it straightforward to add to most under-sink RO systems.

Cons

• Some customers report mixed results on pH increase, so expect modest changes rather than dramatic alkalinity shifts.
• A few users noted sealability or quick connect female connector issues, so extra care at installation may be required.
