725 sq.ft² Cartridge Pool Filter Valve 21207GPH Swimming Pool Filtration System

The 725 sq. ft² filter has a rated filtration capacity of 36 m³/h. It is recommended to use a 3HP~5.5HP water pump to drive the filter.

The 725 sq.ft² filter has an hourly filtration capacity of about 9,000 gallons. With a 4-hour circulation cycle, it can meet the needs of a 36,000-cubic-meter swimming pool. If yours is a small pool and large pool share one circulation system, we believe the 725 sq.ft² filter can fully meet the requirements.

The 725 sq.ft² filter comes with the internal filter cartridges included at the time of purchase, 8 in total.

The filter the user enquired about is the GL720, which has a large filtration area, slow flow rate, and high filtration precision. A filtration precision of 50 microns is quite scientific, and currently, all the ones available for sale are 50 microns.

The 725 square foot filter has a rated filtration capacity of 9500 gallons per hour, but the variable speed pump with a maximum flow rate of 6000 gallons per hour may have insufficient power. Could you provide the pool water capacity data so that we can recommend a suitable filter?
