Tips for Cleaning and Replacing Hot Tub Filters

Hot tubs offer maximum enjoyment for minimal maintenance. The primary maintenance chore is making sure that the water stays clean and fresh. When it comes to health and safety, routine water treatments are critical, but it’s important to make sure that the spa’s equipment is regularly checked and cleaned as well. Although though hot tub parts are designed to provide hours of relaxation for many years to come, filters need to be regularly cleaned and occasionally replaced.

Most spa filters are made with paper or polyester cloth encased in a removable cartridge. As water flows through the product, dirt and particulates are sifted out. Routine cleaning is not only required to make sure that the collected debris doesn’t clog the cartridge, but to extend the life of the cartridge as well. When properly maintained, many cartridge models can last for several years.

Hot Spring filters include cartridges made with ceramic rather than with polyester or paper. Ceramic cartridges not only allow twice as much water flow per minute as conventional models, but require less frequent cleaning than conventional products as well. Hot Spring spas are manufactured by the Watkins Manufacturing Corporation. A subsidiary of the Masco Corporation, Watkins also produces spas under the Watkins, Caldera and Tiger River brands. Depending upon the year, make and model, Caldera and Watkins spa filters as well as Tiger River spa parts may be interchangeable with Hot Spring parts.

The product’s name and model is usually imprinted on the cartridge. If the part number of a particular cartridge isn’t known, spa owners may wish to measure the product’s dimensions before placing an order for a new product. Measurements should be taken of the outside diameter of the end caps, the length from end cap to end cap, the inside top diameter and the bottom inside diameter.

Cleaning tasks include spraying the filter with a garden hose to dislodge debris. To ensure that products like lotions and oils are completely removed, spa manufacturers often recommend soaking the filter in various cleansers as well, including dishwashing liquid, trisodium phosphate solutions and commercial cleaners. A solution that includes muriatic acid is helpful in rinsing out substances like algae, calcium carbonate and various minerals.

To prevent stretching, the filter should be allowed to dry completely before reinserting into the hot tub. Having an extra filter on hand allows users to continue to enjoy the spa while undertaking cleaning tasks.
