Product Overview

The Sundance® 680™ Series 45 Sq Ft Filter Cartridge (part #373043S) is a genuine OEM pleated replacement filter built for the dual‑stage MicroClean® system used on Burlington models from 2008 through 2012, and Hartford and Hawthorne models from 2007 through 2014. Its high‑density pleated Reemay® media is sized to maximize debris removal while keeping pump performance strong over time.

The cartridge measures approximately 6 inches in diameter by 9⅛ inches in length, with a 1½″ MPT threaded bottom connection sized for OEM fit, and a top handle that makes lifting it in and out of the housing straightforward. It's cross‑referenced to common aftermarket equivalents Pleatco PTL47W‑P, Unicel 6CH‑35, and Filbur FC‑0320, so if your existing filter carries one of those numbers, this is the correct OEM match.

Installation is tool‑free: thread the cartridge into the housing using the 1½″ MPT connection, and it's ready to filter. Rinsing the pleated media regularly between full replacements helps maintain flow and extends the time before a full cartridge swap is needed.

  • Power off the spa and open the filter compartment.

    Remove the old cartridge by unthreading it from the housing.

    Thread the new cartridge (#373043S) into the housing using the 1½" MPT connection.

    Secure the lid and restore spa power.

    Rinse regularly and replace every 12-18 months.
