Sundance Spas MicroClean® Filter PN 6540-502

Sundance® Spas MicroClean® Filter – OEM Part #6540-502

Keep your Sundance® Spa water clean, clear, and properly filtered with the Sundance® Spas MicroClean® Filter #6540-502. This disposable depth-loading filter is an important part of the Sundance® MicroClean two-stage filtration system and is designed to capture extremely fine contaminants that may pass through a conventional pleated hot tub filter.

Unlike a traditional pleated filter that can be rinsed and reused, the 6540-502 MicroClean filter is designed to be disposable. Its specialized microfiber media traps fine particles and contaminants throughout the filter material, providing an additional level of filtration for cleaner, clearer spa water.

For best performance, replace the MicroClean filter approximately every 3–4 months.

What Makes the Sundance® MicroClean® Filter Different?

A conventional pleated hot tub filter primarily captures debris on the surface of its filter media and can typically be rinsed and reused.

The Sundance® MicroClean® 6540-502 filter works differently.

Its specialized depth-loading microfiber media captures much finer contaminants throughout the filter material. This allows the MicroClean system to provide an additional stage of filtration beyond what the primary pleated filter can accomplish by itself.

The two filters work together: the larger pleated cartridge handles larger debris and can be periodically cleaned, while the MicroClean filter captures much finer contaminants and is replaced rather than cleaned.

⚠️ Do Not Clean the 6540-502 MicroClean® Filter

The Sundance® 6540-502 MicroClean filter is disposable and should not be cleaned or reused.

Do not:

• Spray it with a garden hose
• Pressure wash it
• Soak it in filter cleaner
• Attempt to scrub or rinse the filter media

Cleaning can damage the specialized filter material and reduce its effectiveness.

Instead, simply remove and replace the MicroClean filter approximately every 3–4 months.

💡 MicroClean® Maintenance Tip

An easy way to maintain your Sundance® MicroClean filtration system is to put the disposable filter on a regular replacement schedule.

While the larger pleated filter should be removed and cleaned periodically, the 6540-502 MicroClean filter should simply be replaced.

Don’t rely only on its appearance to determine when replacement is necessary. Because fine contaminants are captured throughout the depth of the filter media, the cartridge can become loaded even when the outside doesn’t look excessively dirty.
