We suggest changing the filter every 3-4 months normally. It also depends on the actual environment you are using the air purifier. If you use it in a place with high-level air pollution, the filter might request to change 2-3 months. Besides, you can also refer to the filter color whether it turns into dark color from white and gets too much dirt or pollution adsorbate on it.
