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
Note: Collar has open slot (2 notches). Length is measured from one end of the grid to the other (collar not included).
I am changing the grids in the pool filter . the open slot in the filter is in the bottom not on top .would it work .please let me know ,appreciate your assistance .thanks
Hi, Ed. These are not the correct grids for your filter. if you can provide us with the model number to your filter we can locate the correct replacement grids.
who makes this grid?
The manufacturer is Unicel.
I have a Hayward DE 480 S . would your 48 DE grids fit this filter?
Hi Craig, this 48 sqft full grid will fit the Hayward DE 48 filter. If you need to replace all 8 grids you can purchase the 48 Sq. Ft. Grid Pack (FG1004PACK).
will the FG1004 and FG1048 interchange? Will they install in the base?
Hi Jim, The FG1004 and FG1048 are not interchangeable.
I have a 15 yr old Nautilus INS Pac Fab 48 DE filter. Works great. Also own new set of fins for it. After last cleaning now dripping from lower piping assembly underneath/within the skirt/housing below the tank. I think it is probably just o rings etc on that lower piping assembly. 1. What would I need to purchase? Try this first? OR 2. If I buy a new Pentair FNS Plus D.E. Filter, will I be able to use the whole new set of fins I already have for the Nautilus INS Pac Fab 48 DE filter
Hi Rick, I would first start off by replacing key # 26, 31 and 32 located on the Pac Fab Nautilus INS Parts Break Down Page. If you do end up going with a complete FNS Plus 48 Filter then the individual grids will work from the INS to the FNS Plus but the top and bottom manifold are different. So if you have a pre-assembled grid pack you will need to remove the grids.
Is this the right part for the filter formerly called the Nautilus FNS 48
Hi David, Yes this is the proper replacement DE Grid Pack for your Nautilus FNS 48 Filter. We also have a Video on How to Replace your DE Grids which you may find helpful.
I have a Hayward PRO-GRID D.E. Filter DE4820 and need to replace all of the filters inside. What all do i need to order?

Hi Bob, We have specific grids for different filters, if you can provide us with the model of your filter we can verify which grids you need.

I was wondering if these grids will fit my filter. Waterway Crystal Water Filter, DE 48 Sq Ft, Model: 570-0048 Thanks
These are not the correct grids for the Waterway Crystal Water D.E. filter model 570-0048. There is a smaller 48 sq. ft. grid part number 4742-100 and the larger grid part number 4742-103. This model takes 7 of the large grids and 1 of the smaller grid.
I have a Pac-Fab Nautilus FNS 24 filter. Which of the grids will replace the current grids?
How do the FG1004PACK grids compare to the grids that originally came with my filter?
The FG1004PACK are just as good as the grids that come with the filter. Filter manufacturers don't make the grids, they are actually made by either Unicel or Pleatco.
I need to order replacement grids for my d.e filter but I'm not sure which ones to order. How do I know which one is the right one?
The easiest way to figure out the correct grid would be to measure the length and width and compare it to the measurements we have listed on the product page.

All Unicel elements & grids have a 20 Micron Rating.

When I removed the old grid assembly it was totally caked with old DE dirt. Even after back washing. This is the first time disassembling. Brought home about a year ago. Ordered new grid due to DE dirt being pumped back into pool. Wish you offered a complete kit with all 8 grids. Did not understand what a partial grid was until I disassembled the filter unit. Partial means one of the grids a smaller. So I did not order the partial grid. Will have to order this part and disassembly filter again to install this part. Could not find clear instruction on reassembly of grids. Figured it out after about 1/2 an hour. Need to assemble it upside down. And the grids need to start outside of the bottom filter locator circle. There is this molded in circle in the filter locator. The tips of the filter need to be outside of this circle. For the grid to fit properly.
(5 out of 5 stars) D.E. Filter Grids: OEM, great price, on time

Pros: On time, OEM, super price
To be honest I had some trepidation because of some less than stellar reviews. But the price was irresistible. The fileters were shipped same day as promised, arrived within 5 business to Calif. as promised (with the FREE shipping), and were OEM filters in perfect condition. And I saved a boatload of money over other online sellers and my local pool supply. I will definitely use them again.
(5 out of 5 stars) Great Grid

All of our grids were old and tore and it was difficult to keep the pool clean. It was great to receive these grids and we are having an easier time in keeping the pool clean. The on-line ordering was easy and product was received within the time specified.
