Why it matters
The Discount Pool Mart DE4820 DE Grid Set is a replacement pool filter grid set that its listing says replaces dex4800da dex4800ds pg-1904 fc-9440 fc-9340 fg-1004, with 48 sq ft of media.
Match the part number on your old cartridge or filter housing first; if it has worn off, measure length, outside diameter and both center holes. A cartridge that is close but not exact can let dirty water bypass its seals.
