It is very necessary to change filter on regular basis, because it keeps dirt, bugs, bacteria or other nasty thing out of spa. Spa circulars the whole water by filter with trap. You can change your filter, it depends on the quality of the filter that you use, but generally it should be replaced every two-year or a year.
You can purchase three types of filters. Keep in mind what type of filter recommends your spa. Sand filter is the most common filter. As the name indicates, this kind of filter requires specific sand. It has capacity to destroy particles of contaminate from the water.
