Poolzilla Replacement Pool and Spa Filter for 6541-397, Sundance MicroClean Ultra, Sundance 6541-397, AK-6541397, UFC-397

Overview

Bring back the spa days you love with the Poolzilla replacement filter cartridge (SKU 02-03-033), a premium-fit cartridge designed specifically for Sundance spas and larger residential hot tubs. Standing 19 inches tall with a generous 8.375-inch outer diameter, this oversized cartridge provides substantially more pleated filtration surface than smaller spa filters — and more surface area means more dirt capacity, fewer cleanings, and consistently clearer water between rinses. The durable pleated polyester media traps body oils, lotions, hair, and microscopic debris that cloud spa water and irritate skin, while reinforced end caps lock the cartridge securely in place to prevent bypass leaks. The result? Silky, sparkling water that's ready whenever you are, with maintenance that takes minutes instead of headaches.

For best results, rinse this cartridge every four to six weeks with a garden hose to flush out trapped debris, and plan to replace it every 12 to 15 months under normal residential use — or sooner if you notice reduced jet pressure, persistent cloudiness even after shocking, or a chemical balance that won't hold steady. A fresh filter doesn't just clear the water; it reduces strain on your spa pump, lowers chemical consumption, and keeps the water your family soaks in genuinely clean. Swapping it out takes under two minutes: power down the spa, unscrew the old cartridge, thread in your new Poolzilla filter, and you're ready to soak. Order today and keep a spare on the shelf so your spa is always just one quick swap away from crystal-clear comfort.
