Brand: Swimara

Color: Blue & White

Features:

• Perfect Fit for Hot Tub & Spa Systems: Seamlessly replaces PRB25-IN hot tub filter units across various spa systems. Precision-molded end caps and 2-1/8" open cores ensure leak-free sealing and perfect hydraulic alignment for smooth water flow and stable pressure in standard filter housings.
• Advanced Filtration with 3oz Heavy-Duty Media: Built from 3oz trilobal spunbond polyester, this spa filter cartridge captures particles as small as 10 microns while maintaining high flow efficiency. The pleated design maximizes surface area, extends dirt-holding capacity, and reduces cleaning frequency for consistently clear water.
• Durable Construction for Long Service Life: The reinforced PVC core and thermally bonded end caps resist corrosion and deformation under pressure. Fully washable and reusable, each cartridge provides 6–12 months of reliable performance under typical residential or seasonal commercial spa use.
• Precise Dimensions & Optimized Flow Design: Measures 13-5/16" length × 5" outer diameter × 2-1/8" open ends, engineered within ±0.1" tolerance for a secure, leak-free fit. Each filter delivers 25 sq.ft of filtration area (50 sq.ft total for 2-Pack) to maintain laminar water flow and steady filtration performance.
