In order to keep the water in the spa clean and to strive for a good water quality, you should definitely filter the water. The more water is filtered, the better the water quality.
During the filtering process, the water from the Jacuzzi passes through the filter and the dirt sticks to the filter. Filtering alone is obviously not enough to ensure optimal water quality. In addition to filtering, you need to maintain the water level with chlorine and pH. 

How often should you replace your filter?
This depends on various factors. Are there many trees near the spa? Do you go in the water a lot? Is there a jacuzzi party? 
But our golden tip: the more you change your filter, the better your water quality.
