A Guide on Hot Tub Filters: Hot Tub Maintenance For Beginners

Hot Tub Filters

While hot tubs are designed for relaxation, they do require a bit of upkeep to ensure that the water is clean and safe for users. One of the most important components of the system that requires regular attention are hot tub filters. However, cleaning hot tub filters is fairly easy, and the method will depend on the type of filter used.

Common Hot Tub Filter Types

There are hot tub filter types, but these four are the most commonly utilized in modern spas today.

Cartridge Filters: By far the most popular choice of hot tub owners, cartridge filters are typically crafted of paper, fabric or plastic. These feature pleated material housed within a plastic cartridge and simply slide inside the filter housing space inside the spa.

Ceramic Filters: Similar in design to cartridge filters, these are built with a resilient ceramic that generally outlives all other types of filters. With regular maintenance, ceramic filters can last for several years before requiring replacement.

Sand Filters: Sand filters are typically spherical containers filled with sand that removes unwanted substances. They commonly sit outside of the hot tub and require frequent cleaning.

Diatomaceous Earth Filters: Eco-friendly diatomaceous earth filters use fossilized diatoms in lieu of activated carbon, but they work just like cartridge filters.

How to Clean a Hot Tub Filter

The best way to ensure good water quality and increase the longevity of your hot tub is by cleaning the filters regularly. Regardless of the method you perform, it’s imperative to only use a hot tub filter cleaner that is recommended for your model of spa. If you’re wondering how to clean hot tub filters, don’t worry, we have you covered. Here are three recommended cleaning methods for cartridge-style hot tub filters.

  1. Weekly Quick Rinse—Once a week, remove the hot tub filter and give it a good rinse with fresh water, taking time to spread out the pleats and remove any debris or residue. Rinse the filter again, and allow it to air dry before replacing it into the tub.
  2. Monthly Chemical Rinse—Remove the filter once per month and generously spray it down with proper hot tub filter cleaner, which usually comes in a spray bottle. Allow the solution to sit for 15 minutes or as directed on the cleaner. Thoroughly rinse and replace into the spa unit.
  3. Chemical Soaking—Every three or four months it’s advised to perform an overnight chemical soaking of filters, and this is an ideal task to schedule when changing the hot tub’s water. Completely submerge the filter into a hot tub filter cleaning solution diluted according to the instructions and allow it to sit overnight. Rinse thoroughly, allow it to dry and replace the filter.

When to Change Hot Tub Filters

Most manufacturers recommend replacing hot tub filters once a year, with exception to ceramic cartridges that can last for several years. If the cartridge becomes damaged in any way such as bent or ripped media or brittle end caps, it’s essential to replace the unit right away. Operating the spa with dirty or worn out filters is not only hazardous to user’s health, but it can also cause damage to the hot tub itself, for this reason we advise keeping replacement filters on hand. In fact, operating the device with dirty filters may even void the warranty.
