Spa Filter Cartridge for 76136 - Replaces Filbur FC-3960, 71827

Overview

Keep your Hot Spring spa water silky-smooth and crystal clear with the Poolzilla PZ-8465 replacement filter cartridge, purpose-built for Watkins Hot Spring 65 spa systems. With a generous 65 square foot pleated polyester filtration surface, this cartridge captures body oils, lotions, fine sediment, and debris that cloud spa water and dull its sparkle — leaving you with the kind of clean, inviting soak you bought your hot tub for in the first place. Measuring 8.5 inches in outer diameter, 10.5 inches in length, and featuring a 3-inch center hole, the PZ-8465 is engineered to drop right into your Hot Spring filter housing without shims, adapters, or any modifications. Heavy-duty molded end caps create a leak-proof seal so every drop of water passes through the pleats — not around them — meaning more dirt trapped, less work for your pump, and consistently beautiful water week after week.

Hot tub filters work harder than pool filters because the water volume is small and bather loads are high, so plan to rinse your PZ-8465 every two to four weeks with a garden hose and replace it every 12 to 15 months — or sooner if you notice cloudy water that won't clear up after shocking, or if your pump pressure starts running higher than usual. A fresh filter keeps your sanitizer working efficiently, protects your circulation pump from strain, and ensures every soak feels as clean as the first. When replacement day comes, the swap takes about two minutes: power down the spa, unscrew the old cartridge, twist the new Poolzilla filter into place, and you're back to bubbling bliss. Order your PZ-8465 today — and grab a backup while you're at it, so you're always ready for that spontaneous evening soak under the stars.
