How often should I change the filter in my STERRA Moon Air Purifier?

The frequency of filter replacement depends on the model, usage, air quality, and frequency of use. Generally, it is recommended to change the filter every 6 to 8 months. However, it is important to regularly check the filter and replace it when necessary. If the light ring on the air purifier is flashing red, it indicates that the filter may need to be replaced. Please refer to the "Filter Installation" section in the instruction manual for detailed instructions on how to replace the filter.
