What is the flow rate for cartridge filters?

The flow rate for cartridge filters is typically established at 0.375 gallons per minute per square foot (gpm/ft²). This flow rate is based on the optimal performance range designed to ensure efficient filtering while preventing excessive loading of particulates, which could lead to clogging or reduced effectiveness of the filters.

Maintaining this specific flow rate helps extend the lifespan of the cartridges and enhances the overall filtration process by allowing adequate contact time between the water and the filtration medium. This ensures that contaminants can be effectively trapped by the filter material, providing better water quality.

While other flow rates can be applicable in different contexts or systems, 0.375 gpm/ft² is a standard that aligns well with many cartridge filter applications, making it the correct choice in this context.
