Bring balanced minerals back to your RO water

The Waterdrop MNR35-2 remineralization filter is designed to slot into many undersink reverse osmosis setups using a 1/4-inch quick-connect. Instead of sending water through filtration alone, this filter adds back natural minerals, using PCC technology to activate crystalline mineral structures and simulate the mineral-rich experience of spring water. It is a practical upgrade for households that want enhanced mineral content without changing their entire filtration system.

Key benefits and everyday use cases

  • Mineral restoration: calcium, magnesium, sodium, potassium and other natural minerals are reintroduced after RO filtration, helping to balance palate and mouthfeel.
  • Versatile installation: compatible with most RO configurations via 1/4-inch quick-connect tubing; works with under-sink setups and can be connected to refrigerators or other purifiers.
  • Long-lasting performance: designed to operate for 9–12 months or up to 1,100 gallons per filter, whichever comes first.
  • Cost-conscious choice: reduces reliance on bottled mineral water, with the potential to save on ongoing purchases over time.
  • Practical and user-friendly: straightforward, tool-free tubing connections make filter changes manageable and quick.

How it works

The PCC mineral activation process crystallizes minerals to mimic the natural mineral environment found in springs. This approach aims to reintroduce a balanced mineral profile to water after it leaves the RO stage, without altering the core filtration performance of your system.

Natural minerals you may taste

  • Calcium and magnesium for a fuller mouthfeel
  • Sodium and potassium for balanced mineral content
  • Selected natural minerals chosen to complement common RO filtration outcomes

Real-life scenarios

  • Daily tap water that feels crisper and more balanced for drinking and cooking
  • Under-sink installation without changing existing RO routes
  • Connecting to compatible refrigerators or additionalRO purifiers for mineral-rich dispense

Important notes and maintenance

  • This filter is not compatible with Waterdrop X-series RO systems.
  • Do not connect to hot water pipes; install for cold water lines only.
  • When the filter nears end-of-life, replace to maintain mineral restoration performance.
