This is the OEM replacement filter for the Dynamic Collection (78 & 84) & DayDream 3500 models series spas.

According to the manufacturer, the filter needs to be cleaned at least once a month. When you clean your new filter, it’s great to have a second one on hand as the filter you clean needs to dry completely before putting it back into the spa.  With a spare filter on hand, you can enjoy the spa without waiting for the other to dry!
