How To Identify A Replacement Filter Grid

Finding the correct DE grids for your filter can be done using the filter's information tag, measuring your old grids, or using the various part numbers on the filter components to identify your model. Here are some tips to help you find the information you are looking for.

1. Identify Your Filter Model and Size.

Read your filter’s information tag to find the model name and model number. All filters are labeled with an information tag on the tank. This label contains the manufacturer name, model series, and the model number of your particular unit. Most tank information tags will list the entire line for that model, with your specific unit’s size being marked or highlighted in some way.

The most current DE filter model numbers include the square footage of the grids

For example:

The Pentair FNS Plus, 60 Sq Ft, uses a model number variance of FNSP-60.

2. Measure the grids.

If you want to be sure you choose the right grids, you can measure them. Measure the grid's length(not including the port pipe at the top) to identify the square footage of your filter. The pool industry’s standard curved grids come in 5 different sizes 24, 36,48,60, and 72 square feet; their respective lengths are 12, 18, 24, 30, and 36 inches.

Most DE filters use a grid pack of 8, which includes seven full grids, and one partial.
