Filter Media

Swimming Pool Filter Media is the material used within a pool filter to trap impurities, debris, and fine particles, helping maintain crystal-clear water. The type of filter media you choose significantly impacts water quality, filtration efficiency, and maintenance requirements. Common filter media types include sand, glass, diatomaceous earth (DE), and cartridges, each with unique benefits tailored to different filtration needs. Sand is the traditional choice and works by capturing particles as small as 20-30 microns. As water flows through the sand, dirt and debris get trapped within the sand particles, allowing clean water to return to the pool. Sand filters are easy to maintain and can last several years before replacement, with periodic backwashing required to flush out accumulated dirt. Glass media is an eco-friendly alternative to sand, made from recycled glass. It has a finer filtration capacity, trapping particles as small as 5 microns. Glass media also resists compaction and biofilm formation, reducing the need for backwashing and saving water. Its longevity often surpasses that of sand, making it a cost-effective and environmentally friendly option. Diatomaceous earth (DE) is a powdery material derived from fossilized aquatic organisms. DE provides the finest filtration available, capturing particles as small as 3 microns, making it ideal for pools where exceptionally clear water is desired. However, DE filters require regular maintenance and careful handling due to the powder’s composition, which some users may find more demanding. Cartridge media consists of pleated polyester cartridges that filter particles down to 10 microns. Cartridge filters are low-maintenance and do not require backwashing; instead, they can be cleaned by rinsing the cartridge, making them highly water-efficient. Cartridge media works well in smaller pools or spas and offers a straightforward and easy-to-use filtration option. Choosing the right filter media depends on pool size, maintenance preferences, and desired water clarity. Properly selected and maintained, swimming pool filter media plays a crucial role in keeping pool water clean, safe, and inviting, allowing swimmers to enjoy a sparkling pool all season long.
