Yes, our IceChiller has a 20 micron filter with 24/7 water circulation which filters out hair, skin cells, leaves, sand and other debris. Enjoy a clean and clear ice bath at all times, ready for you when you are. Be your own judge of the water condition, and change it when needed. But if you choose not to use sanitizer to disinfect, we recommend changing the water every 3-5 sessions or once per week. We also recommend cleaning the IceChiller's water filter once every 1-2 weeks. You simply unscrew the transparent cover, take out the filter, and rinse it with a brush and tap water, or spray it with a garden hose at high pressure. And replace with a brand new filter once a month to not cause damage to the IceChiller due to restricted water flow.
