Cryspool 04026 Spa Filter Cartridge – 19 sq ft, 2 Pack, Compatible with 4CH-21/PTL18/PTL18P4/FC-0121

Introducing Cryspool 04026, a premium spa filter cartridge designed to fit a range of popular models and deliver dependable water cleanliness between maintenance checks. With an 8 inch length and an outer diameter of 4-5/8 inches, this cartridge features a cone-style top handle and a bottom 1-1/2 inch MPT connection, making replacement straightforward for many spa systems. The 19 square feet of filtration area is engineered to balance efficient flow with thorough particle capture, helping you maintain spa clarity without frequent filter changes. Cryspool is an independent brand, and this filter is designed to work smoothly with the listed models to support your spa routine with ease.

The 04026 model uses advanced trilobal fiber material, a step above standard point-bond fabrics, to increase filtration capacity and durability. This means more robust performance in real-life use, whether you’re relaxing after a long day or rinsing off after a bouncy pool session. The filtration structure is designed to encourage deep penetration of impurities into the pleats, while still allowing for effective cleaning when you service the unit. A well-maintained filter can help keep water moving freely, which may contribute to a steadier flow and cleaner results over time.
