To convert gallons per minute to cubic feet per second, multiply the GPM by the conversion factor (0.133681) and then divide by 60.

Cubic feet per second (CFS) is a unit of flow rate that indicates the volume of fluid passing a point in a system per second. It is commonly used in hydrology, river engineering, and environmental engineering to measure the flow of water in rivers, streams, and other open channels.

Gallons per minute (GPM) is a unit of flow rate that indicates the number of gallons of liquid that flow out of a system in one minute. It is commonly used in the United States to measure the flow rate of water in plumbing systems, irrigation systems, and other fluid transport systems.

This filter kit contains pre and post filters only (membrane not included) and is intended for the semi-annual filters change-outs (between membrane replacements) or if the membrane is purchased separately.

For maximum performance, it is recommended to change all filter cartridges and post filter every 6 months, but replacement schedules will vary with water quality. Membrane elements (sold separately) are recommended to be replaced yearly.
