Spa Filters For Your Hot Tub

[image_with_animation image_url=”6420″ alignment=”center” animation=”Fade In”]

Your hot tub filters are the first and most important measure of protection for your home spa. Without them, you wouldn’t be able to maintain clean water or hygienic conditions to soak in. When you replace them regularly, you also increase the performance and life of your hot tub systems and decrease the amount of money you spend on maintenance down the line.

Before you even begin filling, you can reduce the total dissolved solids (TDS), like dirt and other minerals, with a Microfiber Spa Pre-Filter. Disposable and easy to attach to a garden hose, these convenient pre-filters help to purify the water by sifting out rust, calcium, and sediment before it hits the tub.

Other available options include Microclean™ Ultra and Microclean™ Plus spa filters for the freshest water. Ultra features an interlocking system, the first in the industry, for dual filtration where finer particles are trapped in a second filter after bypassing an outer filter, which has caught the larger particles. Three pleated layers comprise Plus (only for the 880™ Series). This filter has the added ability to trap and remove oils and lotions for extra clean water.

Our 780™ collection of hot tubs and spas uses the Microfiber Filter (top portion) and Microclean™ I Filter (bottom portion) to keep your water crystal clear. They work together to keep everything sanitary, so you can focus on relaxing.

Visit one of our local Sundance® Spa dealers for cleaning supplies, spa covers, and other accessories that will keep your investment in excellent condition for years to come.
