Built for homeowners or renters dealing with hard municipal water who need a set-it-and-forget-it filtration system. Not for those who move frequently, as the 11-stage plumbing setup is a permanent commitment to your under-sink real estate.
Curator's pick: PentaPure 11 Stage RO Plant
While multi-stage systems can be a headache to maintain, the remineralization on this unit actually makes the water taste like water again rather than that flat, 'stripped' taste you get from basic 5-stage setups. Just be ready for the footprint; the tank and housing together take up more cabinet space than you expect.
⚠ Worth knowing: The cost of ownership spikes at the 12-month mark because you aren't just swapping one filter, but a whole suite of cartridges to keep that 11-stage purity claim valid. If you aren't disciplined about labeling your install dates, the pressure drop from clogged membranes will eventually strain your plumbing joints.

How to use this together
1
Install the PentaPure 11-Stage RO Plant
Begin by installing the main PentaPure 11-Stage RO Plant under your sink, connecting it to your cold water supply and drain. This is the core of your filtration system, and proper connection here ensures efficient contaminant removal before the water proceeds to subsequent stages.
2
Connect the Inline Mineral and Alkaline Filters
After the main purification, integrate the Inline Mineral Filter Cartridge and the Alkaline Water Filter Replacement in sequence. These are crucial for reintroducing beneficial minerals and adjusting the water's pH, ensuring that your purified water is not only clean but also healthy and great-tasting.
3
Install the Storage Tank and Faucet
Connect the Reverse Osmosis Storage Tank 3.2 Gallon to the system and install the dedicated faucet on your sink. The storage tank ensures you have a continuous supply of purified water readily available without waiting for filtration, and the faucet provides easy access to your clean drinking water.
4
Monitor Water Quality Regularly
Use the Digital TDS Water Quality Tester to regularly check the Total Dissolved Solids (TDS) levels before and after filtration. This step is vital for monitoring the system's effectiveness and knowing when to replace the Replacement RO Membrane 75 GPD and other filters to maintain peak performance.
