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 .
