A full set of replacement reverse osmosis system filters for the RKIN Flash undersink reverse osmosis system.

Recommended replacement every 12 months:

  • FIRST STAGE FILTRATION:
    5-micron Prefilter reduces Sediment, Rust, and other large particles.
  • SECOND and THIRD STAGE FILTRATION:
    Carbon Block Filter reduces Chlorine and other Disinfection by-products.
    • Option for a third stage filtration Anti-Scale Carbon Prefilter. Use this option only when experiencing a short reverse osmosis membrane lifespan (under 2 years).   
  • FIFTH STAGE OPTIONS:
    • AlcaPure ALKALINE POST FILTER. Polishing Alkaline Post Filter adds minerals, calcium and magnesium, back to filtered water for better taste. It also raises the water's pH to 7-8.
    • Or OnliPure ION EXCHANGE POST FILTER. Polishing OnliPure Post Filter reduces any leftover contaminants after the Reverse Osmosis process to zero TDS. Depending on local water quality and usage the OnliPure post filter might need to be replaced sooner to maintain 0 TDS.

Note: Third Stage Filtration - 75 Gallon Per Day Reverse Osmosis Membrane is NOT included with this bundle. This element needs to be replaced only every 2-4 years, or as-needed. If the reverse osmosis membrane is getting clogged due to high levels of hardness present in the water, please use the bundle option with an Anti-Scale Carbon prefilter.
