The Crystal Quest High Flow Whole House Water Filtration is a point-of-entry filtration system designed for larger homes that need stronger service flow than standard residential systems. It is available in 15 GPM, 20 GPM, and 35 GPM system options, with sizing guidance for homes ranging from 1-3 bathrooms to 6+ bathrooms. Buyers can choose SMART or Eagle media types, along with standalone, anti-scale, or water softener configurations depending on water conditions and treatment goals. The system uses heavy-duty composite fiberglass tanks, high-flow distributors, timer control valves, and adjustable backwash-cycle controls on applicable configurations. For larger properties, estates, and high-demand households, this high flow whole house water filter offers a higher-flow filtration platform than compact or lower-flow cartridge systems.
This Crystal Quest system is built for homes that require higher water demand across multiple fixtures, bathrooms, and daily use points. The 15, 20, and 35 GPM options give buyers a clearer way to match filtration capacity to household size and flow requirements.
The High Flow system is available with SMART or Eagle media options. SMART media uses coconut-shell granular activated carbon, Eagle Redox Alloys, and ion exchange resin, while Eagle media includes activated carbon and Eagle Redox Alloy media with alkalizing and ionizer support.
Buyers can choose the standalone filtration system, add salt-free anti-scale support, or select a water softener configuration. The anti-scale and softener options should be selected based on water hardness, plumbing goals, and whether the property needs conditioning or traditional softening.
With composite fiberglass tanks, high-flow distributors, timer control valves, and adjustable backwash-cycle controls on applicable configurations, this system is designed for larger whole-house applications. Optional accessories and add-on treatment systems should be confirmed against the selected configuration before ordering.
This high-flow system is designed for larger homes where water demand can exceed the capacity of smaller residential filters. It supports whole-house filtration needs across kitchens, bathrooms, laundry, and other daily water-use points.
Choose the flow rate, media type, and configuration that fit your property. Standalone, anti-scale, and softener options give homeowners more flexibility when matching filtration to water conditions and plumbing goals.
