High-Flow Whole-House Water Filtration System
Powerful Filtration Designed for Larger Homes and Higher Water Demand
When multiple showers, appliances, and faucets run at the same time, many standard filtration systems struggle to keep up. Reduced water pressure and inconsistent filtration can quickly become a problem for larger households. The Crystal Quest High Flow SMART Whole House Water Filter is designed to solve this issue by delivering powerful filtration with strong water flow for the entire home. Built for homes with higher water usage, this system can maintain filtration performance while supporting multiple fixtures running simultaneously.Â
Engineered for High Water Demand
Unlike smaller filtration systems that may restrict water pressure, the High Flow system is built with large filtration tanks and high-capacity media to handle significant water usage.
-
15 GPM – suitable for homes with 1–3 bathrooms
-
20 GPM – ideal for homes with 4+ bathrooms
-
35 GPM – designed for large homes, multi-family properties, or light commercial use
This allows multiple fixtures such as showers, dishwashers, and washing machines to operate simultaneously without sacrificing water pressure or filtration performance.
