Once all of this is out of the way, we will look at the best hot tub filter cleaning products available today.

By the end of this article, you will know which hot tub filter cleaning products are best for your needs. This will include things like disinfectants, nozzle cleaners and more.

Let’s get started.

How to Know It’s Time to Clean Your Filter?

If you are reading this then you probably already know that cleaning your hot tub filter is very important.

Unfortunately, hardly any hot tub filters come with a countdown timer of when they need cleaning.

This is also a lot more tricky if you don’t always remember the last time you washed or thoroughly rinsed it.

So, here are some tips to know when it is time to clean your filters.

  • Is the water no longer smooth or pleasant against your skin? Do you feel itchy after using the hot tub? If yes, it might mean that the filters need changing.
  • Has it already been more than three months since your last clean? If so, give your filter a quick rinse through because chances are they need it. For the best results immerse your filter in a cleaning solution. Rinse thoroughly and let it dry before reinstalling.
  • Has it been more than a year since you changed your filter? If so, it is probably time for a new one – depending on your model and manufacturer’s instructions. Most filters will usually begin to get extremely dirty after a year or become weakened by excessive use. So even if the manufacturer says they last longer than a year still thoroughly clean them if you haven’t done so for a long time.

Hot Tub Maintenance

Maintaining the quality of your water is one of the most important aspects of keeping your hot tub healthy and operating at its best. To do this, I have made some suggestions of things you can take into account to make sure you always have a safe and enjoyable hot tub experience.

The tips below will help you improve the quality of your hot tub water and thereby also improving the overall longevity of the device.

3 Top Hot Tub Maintenance Tips

  • pH. Treating your water with regular pH treatments can reduce nitrates, which can accumulate in the water over time. A low level of pH will make the water acidic and therefore less pleasant to use. It can even increase some allergic reactions. To avoid this, regularly test the pH of your water with test strips so as to keep track of the ph level. A pH of 7.4 is neutral and anything below that means the water is acidic. If the pH is too low consider using pH neutralising treatments.
  • Water hardness. Hardness or “hard water” is when the water contains too many hard minerals like calcium. If this happens, your pipes can easily accumulate too much mineral deposits. This will mean that it will be harder for soap to foam and you may find the water unpleasant against your skin. Water hardness treatment can be difficult because you’ll need to treat all the water from the supply source. Your best bet is to get a water softener machine and treat all the water coming into your home. Although this is slightly expensive, you will reap the benefits throughout your home – not just your bath tub. This includes benefits in your kitchen and bathroom plumbing, pipes and appliance
  • Bacteria. You should always pay attention to the signs of potential of bacteria growth in your hot tub. Products like bleach may be able to treat this issue depending on where you find microorganisms such as mold. Also consider using chlorine to keep your water as bacteria-free as possible.
