Pool Filters for Your Pool

Pool Cartridge filters take advantage of pleated cartridges by maximizing the square footage of the filter. The larger the surface area, the more dirt particles you can filter out. Cartridge filters can capture debris as small as 10-15 microns. In terms of efficiency, cartridge filters fall in the middle.

When the pool filter cartridges are dirty or the pressure in your filter rises, it is time to clean them. Depending on the water chemistry, most pool owners clean their cartridges every six months. Cleaning is as easy as using a garden hose to rinse them off. There is no need to backwash a cartridge filter.

Pool filter cartridges work best at slow flow rates. An overly-sized pool pump has the potential to push the water straight through the cartridge filter and bypass the filtering stage altogether. It is important not to oversize your pool pump, especially when using cartridge filters. However, this also makes cartridge filters more efficient. Cartridge filters utilize and waste less water. Unlike sand filters, using a cartridge filter saves you money on chemicals and water.
