The AquaFX 20 Micron Pleated Sediment Filter is a pre-filter cartridge designed to protect your primary reverse osmosis system from large particulate matter. It effectively removes sand, silt, rust, and other coarse sediment from your source water before it reaches the more sensitive stages of your RO/DI unit. This initial filtration step is crucial for improving the efficiency and longevity of your entire water purification setup, ensuring you start with the cleanest possible water for your aquarium.

This 20-inch filter features a pleated design which increases its surface area for greater dirt-holding capacity and lower pressure drop. A key feature is its washability, allowing for reuse and significantly reducing long-term operational costs. With a 20-micron rating, it's specifically engineered to capture larger particles that would otherwise quickly clog finer, more expensive filters, such as 1-micron sediment cartridges and carbon blocks, saving you both time and money on replacements.

This sediment filter is an excellent and highly recommended addition for any aquarist dealing with high levels of sediment in their tap or well water. By installing this unit prior to your main RO system, you provide a robust first line of defense that safeguards your investment. It is the ideal solution for reefers looking to lower maintenance costs and extend the service intervals of their essential water purification equipment, leading to more consistent and reliable pure water production.
