Swimming pool filters are essential for proper water quality and swimmer safety. Even more importantly, it's essential to select the correct size filter for your pool to adequately turn the water. To choose the correct size, select a pool filter with a flow rate that's higher than the size of the gallons per minute (GPM) the pool pump produces.Swimming pool filters trap dust, dirt and sand particles that pass through the skimmer basket and the hair and lint pot. Some are even powerful enough to remove bacteria and particles smaller than the naked eye. It's essential to invest in a high quality filter to achieve consistent, efficient performance year after year. The pool filters at Pool Express come with solid features like advanced programming technology, durable housing that withstands harsh environments, and environmentally friendly performance. Keep in mind to always choose a filter based on the micron rating: The lower the micron rating, the smaller the particles it can remove from your water.
