The Rexener sand filter is suitable for use with the Rexener PR200 heater and Rexener circulating water pump. With the help of a sand filter, you will keep your water crystal clear for a long time.
When you equip your hot-tub with a sand filter, you no longer have to change the water after each bath!
The sand filter can also be used in frost if the water is heated. If the hot-tub or pool is not in use in the winter, the sand filter should be stored in a warm place.
