Don’t worry, this article is here to help.

In this post, I will provide you with a list of the best hot tub replacement filters available to purchase today. You can choose the one for your particular hot tub model and get it in no time (if you decide to buy it online that is).

So let’s get into some honest assessments of the best filter replacement products on the market to see which one can do the best job for you.

Why Are Hot Tub Filters Important?

If you find that your current hot tub filter is not working as it should, you may be tempted to simply remove it and not bother buying a replacement. Do not do this.

Do not use your hot tub without a functioning filter.

Here are some reasons why:

  • Hot tub filters prevent the accumulation of dirt and bacteria in your water. You might be surprised to learn how much bacteria can surround you in your tub if you don’t have a filter despite all your attempts to keep it clean. A warm, moist environment is the perfect breeding ground for many types of bacteria and viruses. However, filters will help to significantly reduce this exposure.Change Bath Tub Filter
  • A good filter stop sediments, minerals, dirt and large debris before they reach you. While cleaning the tub by hand means you are only dealing with the bacteria after it’s already presented itself.
  • The filters in your hot tub can also prevent air from getting into your pipes. Air entering your pipes and the interior of the hot tub can cause significant damage. Especially if it gets to the pump.
  • If a simple $30 cartridge replacement could prevent you having extremely expensive hot tub damage, wouldn’t you take it?
  • Hot tub filters also prevent your nozzles from being damaged. This is because filters stop air or debris getting into the internal system of the tub. Pipes, nozzles, and jets can be a lot harder and more expensive to replace than the filter cartridge. Also if the pipes are too clogged then it can be a much bigger job.
