Pleatco Swimming Pool Filter Cartridge

Check your existing filter for a part number or measure the dimensions of your current cartridge. This model is a direct replacement for Unicel C-7471 and Filbur FC-1977, and it fits systems requiring a 7-inch diameter, 26-inch length, and 3-inch top and bottom openings.

The Free-Flow Core is engineered to allow water to pass through the filter more easily. This reduces the operating pressure on your pool pump, which helps the system run more efficiently and can extend the lifespan of your pump motor.

Yes, the anti-microbial end caps are designed to inhibit the growth of bacteria and algae on the filter itself. While it doesn't replace the need for proper chemical balancing, it helps prevent the filter from becoming a breeding ground for contaminants, leading to cleaner water overall.

While the spun-bonded polyester media is durable, you should rinse the pleats with a garden hose whenever your system's pressure gauge rises 8-10 PSI above the starting level. Depending on your pool's usage and environment, you can typically expect to replace the cartridge entirely every 12 to 18 months.

These bands are crucial because they keep the pleats evenly spaced during operation. When pleats collapse or bunch together, they lose surface area and filtration efficiency; the bands ensure the entire 105 square feet of media remains active and effective.
