Dirty, and clogged hot tub filter cartridges make the water difficult to maintain and can really put a strain on your spa pump. Here are a few simple steps to clean them up.

How to deep clean your hot tub filter in a few simple steps

Even when the filters look clean, they can often be coated with oils, lotions and soaps that can clog and reduce the water flow in your spa. Rinsing it with a garden hose every few weeks can keep larger debris at bay, but a deep clean is required at least every water change. If you use your hot tub frequently or have more use by guests, you may want to deep-clean your filters monthly instead of every 3 to 4 months.

Colorado Springs Hot Tubs can help with the right products to get that deep clean to keep your hot tub’s optimal performance.

Here’s your simple deep-clean method:

  1. Turn the power off to the hot tub and remove the filter. Fill a large plastic bucket (5 gallon works best) with hot or cold water and add your product according to directions on label. Hot water cleans faster, but cold can work, too.
  2. Spray the filter with a garden hose, preferably with a sprayer nozzle for better pressure. Clear off any large debris by spraying at a 45° angle.
  3. Place the filter in the solution, making sure that it is fully submerged. Two or more small filters can soak together in the same bucket.
  4. Soak for at least an hour if you used hot water, and up to overnight for cold water or for very dirty filters.
  5. Rinse the filter again with the hose to remove any leftover residue from the solution.
  6. Finally, replace the filter in the hot tub and you’re done!

If the filters are over a year old, it is recommended to replace them. Deep-cleaning cleans a dirty filter, but it does not make an old filter new.

You can make this process even easier by keeping an extra set of tub filters and rotating them out at each drain and refill or filter cleaning. Then you can set the freshly cleaned filters out to dry and always have a fresh filter to install in it’s place.
