We’ve developed our own line of premium-grade filters for your Sundance Spas™ brand hot tub. Our filters are fully-compatible, fully-effective, and fully-guaranteed. About the only thing that isn’t full is the markup—ours saves you about 20% compared to a Sundance filter. Our spun-polymer microfilter traps tiny bits of sand, pollen, and dust, so your water stays clear and healthy.

The handy two-pack saves you money and helps you keep a steady supply of microfilters. The Hot Tub Things 6540-502 filter will become visibly dingy when it is time to replace it. The filter works with bromine, chlorine, UV-ray, and the SunPurity mineral sanitizer (sold separately). Whatever chemistry you use to keep your spa healthy, this filter can help.

Please note that this filter must be used in combination with the long-lasting Hot Tub Things 6540-501 filter or compatible Sundance filter, sold separately.
