Unicel FAQs
Helpful answers about Unicel filter cartridges, DE grids, dimensions, cleaning and replacement matching.
What replacement filtration products does Unicel make?
Unicel manufactures pool and spa replacement filter cartridges, vertical and rectangular DE grids, filter discs and selected spacers and adapters.
How do I identify the correct Unicel cartridge?
Start with the existing Unicel number or equipment model, then verify cartridge length, outside diameter, inside opening, end-cap style and any handle or thread.
Can I choose a filter cartridge by pool size alone?
No. The cartridge must fit the filter housing and match its required dimensions and configuration. Pool size does not determine physical compatibility.
What do the numbers in a Unicel cartridge listing mean?
The product code identifies a specific configuration, while listings may also show dimensions and approximate filtration area. Use the complete code and specifications.
How do I match a Unicel DE grid?
Verify the filter model, grid shape, length, width, manifold position and whether the grid is full or partial. Similar grid fabrics can have different frames.
How should a Unicel cartridge be cleaned?
Shut down and depressurize the system, remove loose debris with a gentle rinse and use a compatible filter cleaner when needed. Follow the filter and cartridge directions.
When should a Unicel filter element be replaced?
Replace it when cleaning no longer restores normal flow or when the media, pleats, end caps, frame or seals are damaged.
Are Unicel cartridges and DE grids universal replacements?
No. Dimensions, media, end configurations and frames vary. Cross-reference the exact equipment and replacement number.
What if my old cartridge label is unreadable?
Measure the element carefully and record the filter housing model, end-cap design and opening sizes. Unicel's replacement guide can narrow the match.
