The present pool filtering system provides an elongated fine mesh filter with a large surface area; which can be removed and inserted through a standard filter access port found on pool decks. Because the filter assembly length is at least twice the diameter measurement, a large surface area is possible while remaining compact. The filter assembly includes a cylindrical porous filter basket that is completely lined with a filter bag. The filter bag can filter particulate matter as fine as three hundred microns or less. The present filtering system can provide preliminary filtering before water is delivered for further conditioning by secondary filters, heater, or the like. The present filter permits fine filtering without constant clogging or maintenance. When maintenance is required, there is easy access for cleaning and replacement. The elongated weir housing and weir door allows for a greater operating range of pool water level.
