Sundance 880Ultra MicroClean Interior filter

To make your spa water even more sparkling, this filter fits inside a specially-designed outer filter. It catches particles measuring only one micron (one thousandth of a millimeter), which is thirty times smaller than a pleated hot tub filter.

The disadvantage of the micro-filter is that it cannot be cleaned, and its lifespan is therefore relatively short (between 1 and 4 months, depending on usage).
