FULLY COMPATIBLE | The replacement filter fits perfectly in Sundance Select series hot tubs, so you can purify your residential hot tub while saving money over name-brand Sundance filters. See below for a full list of compatible hot tubs that work with the 6540-501 series filter. Please note that this filter must be used in combination with the disposable 6540-502 filter or compatible filter, sold separately.
SUPERIOR FILTRATION | The pleated filtration fabric exposes the maximum surface area to your water flow. Our stiff and woven fabric screens out sediment, microbes, and particles as small as 10 microns in size, so your water stays clear and healthy.
SUITABLE FOR ALL CHEMISTRIES | The filter is compatible with bromine, chlorine, UV-ray, and the Sunpurity mineral sanitizer. Whatever chemistry you use to keep your spa healthy, this filter can help.
NON-SHEDDING | The spunbonded polyester fibers in our hot tub filters will not fray or shed, even in the high heat and increased water flow of modern Sundance hot tubs. Your spa filter should be part of the solution, not part of the problem.
WASHABLE AND REUSABLE | Our hot tub filters and filter cartridges can withstand repeated washings. With proper care and cleaning, one filter will last for a whole year, saving you even more money.

Maintain your water clarity and keep your water clean with a Unicel replacement filter element. Unicel as well as the OEM filter company’s use a spunbonded, 100 percent polyester material called Reemay as their filter medium. Reemay filter fabric is an FDA approved material for milk filtration and is a white material. Some low end manufacturers are using a yellowish material to reduce costs; this is also reducing quality and durability. The Unicel replacement filter elements are designed to the performance standards of the original filter manufacturer. To maximize the life of your filter cartridges and to save on shipping it is recommended to purchase two filters and alternate two sets of cartridges when cleaning.

Hot Tub Things 281 Microban Filter 2-pack (Compatible 10-00281, Wellspring 18 Coreless, Pleatco PBF17 PBF17-M)
$59.95
No reviews
Introducing the newest filter to join our Hot Tub Things family: the Hot Tub Things 10-00281 Filter!
With Bullfrog Spas® being renown for their advanced and revolutionary coreless design, we wanted to bring this type to all our current and new Bullfrog owners. What's the difference? The difference is solely the price-point. For a fraction of the price of replacement Wellspring 281 filters for Bullfrog Spas®, you receive the same high-quality filter technology. No need to sacrifice what that you have grown accustomed with regardless of it being weeks, months, or even years. This helps reduce plastic waste when the times comes to switch out filters. All this is possible with our the Hot Tub Things 10-00281 Filter.
Many have asked: why the blue filter pleats? Is this any different than the white pleats? Is it important?
Not only do we want the physical look of the filters to be a smooth transition for Bullfrog owners, we want the same filter capabilities. The blue pleats are Microban Antimicrobial pleats. With Microban technology, the filter is able to resist the growth of microbes such as bacteria, mold and mildew. Microban protection allows your filter to stay cleaner with longer longevity when compared to regular filter pleats.
