Product Description

Time to Replace Your DE Grids?

Our DE Grids are used on the most common pool filters including American Products, Pentair, Hayward & Pac-Fab. Most DE Filters will require 7 Full Grids and 1 Partial Grid. Typically DE grids last about 5 years so if it has been longer than 5 years than now is the time to replace your DE grids.

Things to Consider When Replacing Your DE Grids

  • Most DE Filters Require 7 Full Grids & 1 Partial Grid
  • DE Grids Normally Last 5 Years
  • Commonly Used on Hayward, Pentair, Pac-Fab and American Products

Note: Collar has open slot (2 notches). Length is measured from one end of the grid to the other (collar not included).

I have an old Hayward Micro Clear D.E Filter model IS-DE2400-95 I need to know what filter element I need to replace all my element. There are 24 Sq. ft. or the 36 Sq. ft. ? Which one will fit my filter? I need to replace all of them. I do not want to replace just one or two and in one or two years or next clean up I another one to replace. Thank you in advance.

Hi, Bob. Based on your model number, the 24 Sq. Ft. Grid Pack (7 Full & 1 Partial) - FG1002PACK is the correct grids. However, to be sure you can follow the steps provided in our How to determine D.E. Filter Grid Size guide.

Hello, could you check the model of your filter or send us some pictures to better help you identify what type of Hayward filter you have?

at the top of the 8 filter grids, there's a cloth attachment in the shape of a tiny banana, or dick. What is this part. It's at the top of the grid assembly for DE filters. Mine has a hole in it and allows DE to enter pool Shaped like a pecker

Hi Mark, We will need to know the model of your filter or the p/n of the manifold in order to locate the correct air bleed sock.
