PentaPure 9 Stage Reverse Osmosis Water Filter System

This bundle features components for a PentaPure 9-stage reverse osmosis system, providing advanced water purification. It is for homeowners seeking to install or maintain a comprehensive water filtration system for improved drinking water quality. These products collectively help achieve clean, purified, and potentially remineralized water through a multi-stage filtration process.

Curated by The Shelf Curator · Updated June 2026

Built for homeowners with high total dissolved solids (TDS) who need a set-it-and-forget-it solution for drinking water. Not for those on low-pressure well systems where a standard storage tank won't fill without additional hardware—this shop focuses on the 2024 updated main unit and its core components.

Curator's pick: Alkaline Remineralization Filter Cartridge

Standard RO water is often too acidic and flat; this specific cartridge is the only reason to choose a 9-stage system over a basic 5-stage setup because it restores the mineral profile and balances the pH to a drinkable level.

⚠ Worth knowing: The 75 GPD rating is a laboratory maximum, not a real-world speed. Expect significantly slower output if your incoming water temperature is cold or if your household goes through more than 3 gallons of water in a single sitting, as the tank recovery time is the bottleneck.

  • Regular replacement of filters and the RO membrane is necessary, which adds to the long-term running cost and maintenance schedule.

How to use this together

  1. 1

    Install the Core System

    First, mount the 9 Stage Reverse Osmosis Water Purification System under your sink. Connect it to your cold water line, ensuring all connections are secure. If you have low water pressure (below 40 PSI), integrate the RO Booster Pump 24V into the incoming water line to optimize performance and water production for the system.

  2. 2

    Connect Membrane and Storage

    Next, carefully insert the 75 GPD Reverse Osmosis Membrane into its housing within the main system. Then, connect the 3.2 Gallon Water Storage Pressure Tank to the purified water outlet of the RO system, ensuring it's positioned to hold water effectively once filtered.

  3. 3

    Add Special Filters & Faucet

    Finally, connect the Alkaline Remineralization Filter Cartridge in sequence after the RO membrane but before the storage tank, as specified in the RO system's instructions. Drill a hole in your sink or countertop for the Luxury Goose Neck Chrome Faucet and connect it to the purified water line from the storage tank for easy access to your freshly filtered, mineral-enhanced water.
