Mistbox alerts you when your filter needs to be replaced. At that time, we automatically ship a replacement filter right to your door. Swapping out water filter cartridges takes only a few seconds.

Turn the water supply off and disconnect the water supply lead from your control unit.

Release the water filter from the control unit by pressing on the button at the front labeled "Water." The water filter will drop down.

Insert the new water filter back into the same area of the control unit where the old one was removed. You should feel a click to know the filter is firmly in place.

Reconnect the water supply lead to your control unit and turn your water supply on.
