The cartridge pool filter is just about the least expensive form of pool filter there is and also the easiest to maintain. It’s because it was quite unpopular with service guys in the early 80’s. The older cartridge pool filters had dozens of little cartridges and frankly they were a nuisance to clean. Today’s cartridge pool filters generally have 4 or fewer cartridges and boast a total filter area of 300 to 500 square feet, thus requiring cleaning less often. Today’s cartridge pool filters filter more finely because the flow rate per square foot of pool filter material is much less. The slower the water flows through the pool filter media, the better it will filter. Cartridge pool filters remove particulate down to about 20 microns in size.
