In the second part of this series, we’ll continue to take a look at hot tub problems that can disrupt your experience and what to do if they happen to you. Hot tub filters remove impurities and particles to ensure your system keeps working efficiently. Continually checking and maintaining your hot tub filter can help avoid filter problems. Taking care of your water is important to avoid potential skin rashes. Being aware of how to take care of your hot tub filters and what constitutes a damaged filter can help you take care of your tub water.


Potential problems with your filter

As a hot tub owner, there’s more than just one potential issue that can tell you it’s time for a filter change. Here’s a few ways to tell that it’s time for new filters:

  • Your spa filter is brown, gray or green, or stays yellow even after cleaning
  • The filtering element (pleated part) becomes flat and loses its fibrous sheen, starts to shred, or come apart
  • The core of the filter is clogged with debris
  • Top or bottom of the filter has a crack or is split
  • Holes in the spa filter or fuzzy filters


Cleaning and replacing hot tub filters

We recommended cleaning your hot tub filters every 4 weeks, regardless of the frequency of use. As well always clean your hot tub filters when you drain and refill the hot tub for the best water quality. It’s recommended to have a spare set of filters on hand so that you have uninterrupted use of your hot tub.

When you have to remove the filters, be sure to shut off the power to the hot tub first. Then check for anything hiding in the outlet area and other objects or debris that may be floating around the spa that could get sucked down into the pipes below. The main goal of hot tub maintenance, specifically filter care, is to have clean, clear water with a minimum amount of chemicals and optimal water flow throughout the hot tub. Replacing your hot tub filters every 2-3 years can help avoid hot tub problems.

Generally speaking, the best way to clean your filters is to use a hot tub filter cleaning product diluted with water.

  • Let your filter(s) soak in the solution overnight or 24 hours in a clean bucket or pail
  • Thoroughly rinse with water prior to placing them back in your hot tub
