OnliPure Edition Replacement filter set for Zero Installation Purifier Countertop Reverse Osmosis System.

• FIRST STAGE FILTRATION: 5-micron Prefilter removes Sediment, Rust and other large particles.
• SECOND STAGE FILTRATION: Carbon Block Filter removes Chlorine and other Disinfection by-products. NEW Option for Anti-Scale Carbon Prefilter. Use the Anti-Scale bundle option only when experiencing a short reverse osmosis membrane lifespan (under two years). NOTE: A brand new reverse osmosis membrane is also required when switching to the Anti-Scale bundle.
• FOURTH STAGE: OnliPure ION EXCHANGE POST FILTER. Polishing OnliPure Post Filter reduces any leftover contaminants after the Reverse Osmosis process to zero TDS. Measure and confirm from your home with a simple TDS meter.

Note: Third Stage Purification - 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 OnliPure Bundle option with Anti-Scale Carbon prefilter.

Note: If converting from AlcaPure Edition to OnliPure Edition by using this filter bundle, then larger attachment clips are required.
