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. If you are considering this, take a step back and consider how important a hot tub bath filter is to the functionality of the entire hot tub system. Here is why:

  • preveHot tub filters prevent the ingress of dirt and bacteria into the water. When you sink into your hot tub, you may not be aware of how many bacteria could surround you if you did not have a filter. A warm, moist environment is the perfect breeding ground for many types of bacteria, but filters can help to significantly reduce this exposure. You can also stop sediments, minerals, dirt and large debris before they reach you.
  • The filters in your hot tub can prevent air from getting into your pipes. If air enters the pipes and the interior of the hot tub, it can cause significant damage. Especially if it is possible to get to the pump. If a simple replacement of the $20 cartridge could prevent you from having this problem, wouldn’t you take it?
  • Hot tub filters can prevent your nozzles from being damaged. When air or debris gets into the pipes, they can sometimes become overloaded. When that happens you will not have any pleasant soothing bubbles while you enjoy your hot tub. Jets can be harder to replace than the filter cartridge, and if the pipes are too clogged, it can be a much bigger job than you ever thought. Always keep a filter to prevent this.
