Benefits of a Saltwater System

Long story short, a salt chlorine generator can turn your hot tub into a healthier relaxing environment for the entire family. Let us start off by saying that you can buy hot tubs with the integrated saltwater system, but they would cost you a small fortune. However, if you already own an inflatable hot tub, you can easily buy a system that will turn your tub into a regular wonderland. Some of the benefits of such a system include:

  • Easier maintenance: This is one of the main selling points of such a system. The cleaning process for such a generator is a dozen times simpler compared to other sanitizers.
  • Doesn’t contain irritants: Saltwater hot tubs don’t have any chloramines. These are a result of ammonia and chlorine interaction and are considered a by-product that might lead to skin irritation. people who are sensitive to chlorine should definitely try a saltwater system.
  • Eliminates the need for sanitizers: With a saltwater hot tub, you will no longer have to worry about chlorine. That’s one less worry for hot tub owners.
  • Increases water buoyancy: In translation, the water puts less stress on the body, which leads to a better experience overall.

  • Makes water softer: Believe it or not, this natural form of chlorine is softer on the skin, reducing the chances of dry or cracked skin (which can be a consequence of pools that use regular chlorine systems).
  • Pleasant odor: Hot tubs that use all sorts of weird sanitizers and chemical solutions might end up giving off an unpleasant smell. With a salt system, you can prevent chlorine mutation, which leads to a fresh water scent, making your dipping experience much more pleasant.
  • Reduced costs: Purchasing a saltwater hot tub is expensive, but when you purchase an inflatable tub and a saltwater system separately, you end up paying less money.
  • Healthy: These are relaxing and therapeutic, making them great for your health.

Downsides of a Saltwater System

Having a saltwater system is way better than using a traditional sanitizer and soaking in potentially harmful chemicals. However, these systems are not without flaws but, yet again, which product isn’t?

  • While the initial costs of purchasing a saltwater system + hot tub combo are lower, it is still one additional cost compared to how much you would pay for a simple hot tub, without this type of generator.
  • These systems have a cell that usually has a lifespan of between two to five years. When the cell eventually dies out, you will have to replace it. Even if they are not all that expensive, it is still an additional cost that hot tub owners have to take into consideration.
  • The laws of chemistry have taught us that salt is corrosive to metal. This means that there are certain elements that are exposed to corrosion, such as heaters or underwater lighting, as these are sensitive to high salt levels.
