48 Sq.Ft FS-2004 DE Grid Pool Filter Set - Effective 7+1 Replacement

In this review of the 48 Sq.Ft FS-2004 DE grid pool filter set, the bottom line is practical: it is a straightforward, compatible replacement for owners of specific 48 sq.ft. DE tanks who want reliable filtration without buying an OEM cartridge. The reviewer found the set best for pool owners using Unicel FS-2004 style cartridges or Hayward Pro-Grid DE4820 style housings, since the set matches the required 48 sq.ft. area and the 24 in height. The single biggest reason to buy is performance per dollar: robust ABS construction and dense nylon mesh deliver clear water and long life at a lower cost than many branded originals.

Key Features

• Compatibility: Designed to fit Unicel FS-2004 and several equivalent models so buyers can replace a tired grid without retooling the entire filter system.
• Complete set: Includes seven full grids and one partial grid so the full 48 sq.ft. pack covers a full cartridge assembly for immediate swap-in.
• Durable materials: Hard ABS frames and high-density nylon mesh resist wear and maintain filtration performance over many cleaning cycles.
• Fine filtration: The grids trap debris down to about 2-5 microns, capturing hair, sand and fine particles for visibly clearer water.
• Easy maintenance: Grids rinse clean with a hose and air dry quickly, making routine care simple and fast.

Who It's For

This replacement grid set is aimed at residential pool owners or maintenance professionals who already have a DE filter housing that takes 48 sq.ft. of grid area, such as units specified for FS-2004 or Hayward Pro-Grid DE4820. It is a practical option for people who want a value replacement that matches original dimensions and filtration area.

It is not for owners of 36, 60 or 72 sq.ft. systems or those unsure of their model; buyers should confirm the FS-2004 or equivalent model number before ordering. If someone needs a custom or nonstandard size, they should look for the exact square-foot match rather than this 48 sq.ft. set.

Pros & Cons

Pros

• Good fit for compatible housings, so installation is usually straightforward for the correct model.
• High filtration efficiency from the dense mesh produces noticeably clear water.
• Durable ABS frames and heavy stitching extend service life and reduce replacement frequency.

Cons

• Only fits 48 sq.ft. systems; will not work for 36, 60 or 72 sq.ft. units.
• Some users reported mixed experiences with ease of installation, so novice installers may need patience or assistance.
