We offer universal sizing (2521, 2540, 4021 and 4040, 8040) to help ensure easy replacement for existing systems if the model number is compatible. May I provide you with a PDF data sheet about that membrane?
We are not in a position to "recommend" a specific filter, just to help them find the correct replacement if we have it.
