About This

• Genuine Aqua Flo Filters — Engineered Exclusively for the 475QC-3 System – These are authentic Aqua Flo 475 filters built to exact specifications for the 475QC-3 ultrafiltration system. Purpose-built cartridges seat, seal, and perform correctly in every stage — no adapters, no compatibility guesswork, no workarounds. Using genuine Aqua Flo filters protects your system and ensures consistent filtration performance at every service interval.
• The 6-Month Service Kit for Your Aqua Flo 475QC-3 Ultrafiltration System – Genuine Aqua Flo filters designed specifically for the 3-stage 475QC-3 ultrafiltration system. This kit includes the two filters due at your mid-year service interval: Stage 1 – Sediment Pre-Filter (65010086, replace every 6 months); Stage 2 – Carbon Block Filter (65010088, replace every 6 months). UF membrane not included — it's replaced separately on its annual schedule.
• Save Money by Not Replacing the UF Membrane Early – The manufacturer recommends replacing the sediment and carbon filters every 6 months and the UF-10 ultrafiltration membrane every 12 months. Since the membrane stays in place at the 6-month mark, this genuine Aqua Flo kit gives you exactly the two filters you need without paying for a membrane you don't. For your annual 12-month service including the UF membrane, see the Aqua Flo 475QC-3 3-filter annual kit (sold separately).
• Reduces Chlorine, VOCs, THMs, Taste, Odor & Sediment – The 5-micron sediment pre-filter traps dirt, sand, and rust to protect your UF membrane and extend its service life. The coconut-shell carbon block filter reduces chlorine, VOCs (pesticides, herbicides, chemicals), THMs, taste, and odor — keeping your water fresh and great-tasting between annual full-kit replacements.
• Tool-Free Quick-Change Design – Every genuine Aqua Flo filter in this kit uses the twist-lock quick-change system. Swap both filters 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 — guide each cartridge into the correct stage every time.
