About This

• Complete Annual Replacement in One Kit – Includes all 4 genuine Aqua Flo filters for a full service of your Aqua Flo 475QC-4 system: Stage 1 – Sediment Pre-Filter (65010086, replace every 6–12 months); Stage 2 – Carbon Block Pre-Filter (65010088, replace every 6–12 months); Stage 3 – 75 GPD RO Membrane (70010014, replace every 12 months); Stage 4 – Carbon Block Post-Filter (65010088, replace every 6–12 months). No guessing what to order – everything ships together for a full annual service.
• Tool-Free Quick-Change Design – Every filter in this kit uses Aqua Flo's twist-lock quick-change system. Swap all four stages in minutes with no wrenches, no plumbing, and no need to shut off the water supply. Color-coded caps (blue for sediment, purple for carbon) make it easy to drop the right filter into the right stage every time.
• Removes Sediment, Chlorine, and Up to 95% of Total Dissolved Solids – The 5-micron sediment filter traps dirt, sand, and rust. Dual coconut-shell carbon filters reduce chlorine, taste, and odor. The thin-film composite Aqua Flo 475 RO membrane removes up to 95% of TDS, including heavy metals, nitrates, and fluoride for crisp, great-tasting drinking water.
• Engineered for the Aqua Flo 475QC-4 RO System – These Aqua Flo 475 reverse osmosis filters are the exact replacement kit for the 475QC-4 four-stage under-sink system. Color-coded, purpose-built cartridges seat and seal correctly in every stage – no adapters or workarounds needed.
• Annual Kit with a Mid-Year Service Reminder – The sediment and carbon Aqua Flo 475 filters are rated for up to 900–1,500 gallons (approx. 6 months). The RO membrane lasts 12 months under normal use. For mid-year maintenance around 6 months, pair with the Aqua Flo 475QC-3 filter pack (sold separately, without membrane) to keep your system performing between full annual replacements.
