The machine doesn’t require any excessive maintenance; you just need to be apt in changing the filters in a timely fashion. If the indicator light at the bottom is blue, that means your system and filter are working perfectly. It will start to blink red when the filter is at its 90% capacity and will turn full red when it reaches its maximum capacity. Make sure to monitor this to replace your filters timely.
A noteworthy aspect here is that the light works on the basis of time. This means that there is no meter or measuring unit in the system that will assess how much water has been consumed. Therefore, if you are using the same filter for three months, then the light will become red, regardless of your water consumption.
Hence, if you have a family of two or live alone and are certain that your water consumption in three months has been far less than 320 gallons, then you don’t need to change the filter when the light turns red. Just reset it with the reset button, and you can get another three months before the light turns red again. However, never exceed six months, and definitely change your filter the second time.
