An air purification prompting method, characterized in that the method comprises: acquiring air quality data, the air quality data comprising the following data: air quality data inside a space where an air purifier is deployed, and air quality data outside the space where the air purifier is deployed; and determining whether to make a prompt according to the air quality data; sending corresponding prompting information when it is determined to make a prompt; wherein the air purification prompting method is performed by a user equipment connected in a wired manner or wireless manner to the air purifier, wherein the step of determining whether to make a prompt according to the air quality data comprises: determining to make a first type prompt if it is determined according to the air quality data that air quality outside the space where the air purifier is deployed is better than air quality inside the space where the air purifier is deployed, the air quality outside the space where the air purifier is deployed is better than a predetermined value, and the air purifier is in a running state; or determining to make a second type prompt if it is determined according to the air quality data that air quality inside the space where the air purifier is deployed is poorer than a predetermined value and the air purifier is in a non-running state; or determining to make a third type prompt if, after the air purifier is started and has run for a predetermined time period, it is determined according to the air quality data that air quality inside the space where the air purifier is deployed is still poorer than a predetermined value, wherein the first type prompt is configured to prompt the user to turn off the air purifier and open a door and a window, the second type prompt is configured to prompt the user to turn on the air purifier and close the door and the window, and the third type prompt is configured to prompt the user to check states of the air purifier, the door and the window, enabling a user to perform a corresponding control operations according to a practical prompt type. acquiring air quality data, the air quality data comprising the following data: air quality data inside a space where an air purifier is deployed, and air quality data outside the space where the air purifier is deployed; and determining whether to make a prompt according to the air quality data; sending corresponding prompting information when it is determined to make a prompt; wherein the air purification prompting method is performed by a user equipment connected in a wired manner or wireless manner to the air purifier, wherein the step of determining whether to make a prompt according to the air quality data comprises: determining to make a first type prompt if it is determined according to the air quality data that air quality outside the space where the air purifier is deployed is better than air quality inside the space where the air purifier is deployed, the air quality outside the space where the air purifier is deployed is better than a predetermined value, and the air purifier is in a running state; or determining to make a second type prompt if it is determined according to the air quality data that air quality inside the space where the air purifier is deployed is poorer than a predetermined value and the air purifier is in a non-running state; or determining to make a third type prompt if, after the air purifier is started and has run for a predetermined time period, it is determined according to the air quality data that air quality inside the space where the air purifier is deployed is still poorer than a predetermined value, wherein the first type prompt is configured to prompt the user to turn off the air purifier and open a door and a window, the second type prompt is configured to prompt the user to turn on the air purifier and close the door and the window, and the third type prompt is configured to prompt the user to check states of the air purifier, the door and the window, enabling a user to perform a corresponding control operations according to a practical prompt type.
