Product details

The SuperPro FC-9845 is a replacement D.E. filter grid measuring 16-1/2 inches by 18 inches. It is sold individually, so check how many grids of this size sit in your element set before ordering.

What the grid does

A D.E. filter does not trap dirt in the grid itself. The grid is a fabric covered frame that holds a coat of diatomaceous earth, and it is that powder layer doing the filtering. When the fabric splits, pulls away from the frame or blinds over with oils and scale, the powder washes through instead of holding, and the pool gets cloudy while D.E. blows back through the returns.

Before you order

Measure the grid you are replacing. Element sets commonly combine several full height grids with one or two shorter partial grids, and only the ones matching 16-1/2 by 18 inches are covered by this part. If the set is original to the filter, plan on doing the whole set at once rather than opening the tank again in a season.

Questions and answers

What people ask about this product, answered by our pool techs.

How many of these does my filter take?
That depends on the filter model. Count the grids of this size in your element set, since most D.E. filters mix full size and partial grids.
How do I know a grid has failed?
D.E. powder coming back into the pool through the returns after a fresh charge usually means a grid is torn or the fabric has separated from the frame.
Should I replace one grid or all of them?
If the set is original and one grid has failed from age, the rest are close behind. Replacing the whole set saves taking the filter apart twice.
What size is this grid?
16-1/2 inches by 18 inches.
