Filter Grids

  • A D.E. (diatomaceous earth) filter contains filter grids inside using D.E. as a filter media to coat the grids. This provides the most in filtration capability out of all the filters used for pools. Like sand filters, they also require backwashing. This flushes out the dirt and debris that the coated grids collected. Then after you complete a backwash, you need to replenish the D.E. filter media to cover the grids inside again.
  • When replacing DE filter grids, the easiest way to identify which size grids to get is to measure the height of the grid. For example, if the height of the grid is 24 inches tall, that indicates the filter is a 48 Sq Ft D.E. filter. So if you multiply the height of the grid by two, you get the square footage of filtration of the DE filter.
      • Typically, a complete grid set consists of eight total grids including one partially sized and seven full grids. The full and partial grid names refer to the width of the grids and not the height. The reason why one grid is a partial size is so that the cluster of DE grids will be able to accommodate for the standpipe that’s in the bottom filter tank. There are other designs of filter grids where they are all the same size, so it’s important to know the manufacturer and model of your D.E. filter.
          • Grids are sold individually in full and partial sizes, sold as sets of 7 full and one partial, and if offered by the manufacturer sold as a complete grid pack.
