Sta-Rite D.E. Module

The best way to verify compatibility is to check the label on your existing filter tank or refer to your owner's manual for the required square footage. This module is specifically designed for systems requiring a 72-square-foot D.E. grid assembly, so matching that exact specification is critical for proper fit and filtration performance.

This is a complete D.E. filter module, which includes the grids and the internal assembly structure. It is designed to be a drop-in replacement, meaning you can swap out your old, worn-out module for this new one without needing to assemble individual grids.

D.E. (Diatomaceous Earth) filters are widely considered the gold standard for water clarity because they can trap much smaller particles—down to 3-5 microns—than standard cartridge or sand filters. This module restores that high-level filtration capability, ensuring your pool water remains exceptionally clear.

This module is designed as a direct replacement component and typically arrives ready to install into your existing tank. You should retain your original tank hardware, such as the clamp band and O-rings, as this module focuses on the internal filtration assembly itself.

While the lifespan depends on your pool's usage, water chemistry, and maintenance habits, a well-maintained D.E. module can last several years. You should consider replacing it if you notice the grids are damaged, if the filter pressure remains high after a thorough backwash, or if you see D.E. powder returning to the pool.
