What are the Types of Sanitizers used in Spa?

Picking a sanitizer should not simply be a matter of what is most affordable, it is a decision that needs to be based on the needs of the consumer, as well as what will keep them and their households healthiest. A huge family that utilizes the Spa sometimes will have various needs, for instance, then a couple who utilizes it once in a month.

Types of sanitizers

Sanitizers can be placed into two main groups:

  • non-residual
  • residual


Non-residual sanitizers will disinfect water when it undergoes the system, indicating that in order to be entirely sterilized, all the water from a health facility should have gone through one specific factor in the pipes. Furthermore, not all of these systems kill all the impurities. For both reasons, sanitization of non-residual type is thought about strictly supplemental and must be utilized just in conjunction to a major recurring sanitizer. These non-residual systems, like UV lights, ozone generators, as well as ionizers, will provide users more benefits of utilizing fewer chemicals.


These sanitizers work by constructing a financial institution of disinfecting chemicals in the water. The spa chemicals remain suspended with the water, prepared to act when an impurity is presented. Unlike non-residual, in which the water might need to flow for some minutes before their treatment, the chemicals are able to kill impurities the second they are presented. After responding, a particle of sanitizer will be spent, calling for the addition of new sanitizer in the water. Presently, the two sanitizers registered with the EPA are chlorine as well as bromine. Products that do not need to be signed up with among these governing bodies may be safe, but will not be strong sufficient to be reliable.
