Spa Filter Cartridge for Pleatco PWK30 - Replaces Unicel C-6430, APCC7095

Overview

Bring back that just-installed clarity to your hot tub with the Poolzilla replacement filter for the Watkins Hot Spring 30. Built with deeply pleated polyester media, this cartridge captures the oils, lotions, hair, and fine particles that turn spa water cloudy — so every soak feels as fresh as the first one. Measuring 10⅜ inches tall with a 5⅞-inch outer diameter and a 1 15/16-inch center hole, it's sized to drop precisely into your existing Hot Spring filter housing with no shimming, trimming, or adapters. Sturdy molded end caps create a leak-tight seal that prevents dirty water from slipping past, and the high-surface-area pleats mean your filter traps more debris between rinses — which translates to clearer water, less chemical use, and a spa that's always ready for company.

Because hot tubs run warmer water with heavier bather loads than pools, plan to rinse this cartridge every two to four weeks and replace it every three to four months with regular year-round use (or about every six months for lighter, seasonal soaking). Watch for the telltale signs it's time for a fresh one: water that stays cloudy even after shocking, foam that won't quit, or a noticeable jump in pump pressure. A worn-out filter forces your pump to work harder, throws off your chemistry, and shortens the lifespan of your spa equipment — all easily prevented with a quick swap. Order your Poolzilla Hot Spring 30 replacement today, and consider grabbing a spare while you're at it so you can rotate cartridges and keep your spa crystal clear all year long.
