Jacuzzi 6473-157J Spa Filter Cartridge 40 Sq Ft – Replacement for J-400 & J-500 Series

Experience clear, balanced spa water with the Jacuzzi 6473-157J Spa Filter Cartridge. Designed as a replacement for J-400 and J-500 Series hot tubs (including J-495, J-425, J-480), this high-performance cartridge packs a 40 sq ft filtration area into a compact, reusable package.

Why this filter matters

With dual-stage filtration, the cartridge captures oils, sediments, and fine particles before they can circulate back into your spa. The result is water that looks brighter, feels cleaner, and supports steady water chemistry—without the guesswork.

• Dual-stage filtration targets a wide range of impurities for clearer water.
• Premium washable materials resist wear, enabling multiple rinses without sacrificing strength.

Key features in everyday use

The slide-in design makes installation tool-free, so you can swap filters quickly between soaks. Compatible with popular spa setups, it works as a straightforward replacement filter to keep your hot tub ready for guests or a private evening soak.

• Easy installation and operation help you maintain steady water flow.
• Durable Reemay pleated fabric stands up to repeated rinses, offering long-lasting filtration performance.

Benefits you may notice

Cleaner water often means less pump strain and smoother filtration cycles, which may contribute to longer equipment life and more consistent spa experiences. While results vary, many users report a noticeable difference in clarity and balance after a filter change.

To maximize life, rinse the cartridge with a garden hose between uses and let it air dry before reinstalling. When time comes for replacement, this cartridge provides a direct, reliable fit for compatible Jacuzzi models.
