How to Know it’s Time to Clean Your Filter

You probably already know that cleaning your hot tub filter is very important, but did you know that there are ways to tell when it’s time to keep it clean? You might already be on something of a cleaning schedule, but it can be difficult to remember to keep your filter clean, especially if you don’t keep track of the last time you gave it a good soak or rinse. Follow the tips below and you’ll be able to recognize when it’s time to clean your hot tub filter easily.

  • Do you feel itchy or dry after soaking in your hot tub? Many times, when you need to clean your filter, you’ll notice the water is no longer smooth and comfortable to soak in. If you feel uncomfortable after getting out of your hot tub, it might be time to clean the filter.
  • Has it been more than a month since your last rinsing? If so, check your filter. There might be grime or dirt building up that you can rinse off easily with your garden hose.
  • Has it been more than three months since your last cleaning? If so, remove your filter and soak it in a cleaning solution. Rinse it off well before you install it once again.
  • Has it been more than a year since you changed your filter? If so, it’s probably time for a new one. Most filters can’t be used for more than a year without needing to be replaced. They usually start to get too dirty after this amount of time or may start to weaken from overuse.

Other Hot Tub Tips

Although cleanliness and water sanitization are some of the most important aspects of hot tub maintenance and upkeep, there are a few other things you should keep in mind in order to have a safe and pleasant hot tub experience at all times. Remember these tips and you should have no trouble improving the quality of your overall hot tub water so that you, your family, and your friends can have a great time with plenty of excellent soaks in your future.

  • pH – Treating your water with regular pH treatments can help cut back on nitrates that can build up in water over time. This can also make the water much more comfortable for you to use, and can even cut back on potential allergic reactions you might experience from frequent exposure to unbalanced water. Test your water’s pH often with test strips from your pool supply store.
  • Alkalinity – Water of a certain pH level is too alkaline and can cause damage to your plumbing as well as to your body, depending on how sensitive you are. Treat your water for alkalinity regularly if this is the case.
  • Water hardness – Hardness is when water has too much calcium present. When this happens, your pipes can develop build-up easily, and you can experience discomfort when using your hot tub. Treating water hardness can be difficult, but you should be able to get it under control with the right chemicals.
  • Bacteria – Last but not least, you should always be aware of the potential for bacteria in your hot tub water. The temperature of hot tub water has a lot to do with bacteria, so monitor that temperature regularly with a hot tub thermometer. Be sure to treat with chlorine to keep your water as free from bacteria as possible.
