Effortless spa maintenance with the Sundance Microclean I Throwaway Absorption Filter 6540-502

Meet a small, single-use filter designed to simplify your routine spa care. The Sundance Microclean I lives up to its name by offering a straightforward, no-hassle approach to filtration. Its compact 8.5-inch diameter fits select Sundance housing, and the disposable design means a fresh filter each time you swap it in—no soaking, no scrubbing, and no guesswork about cleaners or conditioners. For many spa owners, that simplicity translates into more time enjoying the water and less time attending to equipment.

Beyond convenience, this filter supports consistent water clarity by providing a fresh barrier between the spa’s circulating water and the filtration system. While it is not a guarantee of results, the one-way, disposable design aligns with a simple maintenance rhythm: replace on a schedule and keep the water flowing freely. It’s built for use with Sundance Spas in the 850 and 780 Series families, making compatibility a straightforward part of your spa setup.
