Unicel is American’s leading manufacturer of swimming pool filter replacement cartridges and D.E. filter grids.

Unicel curved vertical D.E grids slotted collar type – Pac Fab, American, Hayward, and Pentair, are interchangeable (assuming full size grids are replaced with full size and small grids with smalls). Unicel offers one all-purpose replacement series.

• Higher Yarn Count + Finer Denier + Higher Permeability
• Less Resistance to Water Flow
• Longer Cycle Runs Between Backwashes
• Better D.E Powder Caking Properties

The cloth used on Unicel’s D.E. grids is 100% Polypropylene. This fiber, a member of the Polyolefin family, has excellent resistance to acids, alkalis, and abrasion, in addition to being both rot and mildew resistant. The use of polypropylene cloth for swimming pool filtration was originally developed by Meissner Mfg. Co. (Unicel’s parent company) during the 1950s. Throughout the forty-year span that polypropylene cloth has been used in this application, this fabric has gone through several modifications. Improvements to critical properties such as yarn construction, weave pattern, and fabric finishing have allowed us to better control the fabric’s “permeability” in order to optimize the D.E. cake handling characteristics. Permeability is the cloth’s flow resistance, expressed in “cubic feet per minute” of airflow as measured with a Frazier permeability machine.

If D.E. grid cloth has too low a permeability, it will blind off quickly, resulting in short filter runs and frequent backwashing. On the other hand, if the material has too high permeability, D.E. can bleed back into the pool. For this reason, all polypropylene grid cloth used by Unicel (and Meissner Mfg.) is woven and finished to our exacting permeability specifications. As a result, we can assure the user the optimum in filtration efficiency, dirt holding, and cake release properties without D.E. kick back or short filter runs.

Usage in Singapore

Unicel elements are widely used in swimming pools at condominiums, hotels, resorts, and clubs in Singapore due to their superior filtration efficiency and durability. These high-performance filter cartridges, made from advanced synthetic materials, provide excellent dirt-holding capacity and require less frequent cleaning compared to traditional sand or DE filters. Their compact design makes them ideal for space-constrained urban settings, while their resistance to chemicals and UV degradation ensures long-lasting performance in Singapore’s tropical climate. Additionally, Unicel elements are eco-friendly, reducing water wastage during backwashing and lowering maintenance costs. Their reliability and ease of maintenance have made them a preferred choice for commercial and residential pools across the country, ensuring crystal-clear water quality for guests and residents alike.
