For example, since the filter 101 may be disposed inside the air purifier 100 , direct management of the filter 101 by a user may be difficult. The filter 101 can be managed efficiently and conveniently by being managed based on a control signal received from a server, a computer, a smart phone, and the like.

The filter detection unit 102 may detect state information of the filter 101 . Here, the state information may include the filter usage time, usage environment, performance, size, usage, and the like. For example, the state information may be a comprehensive indicator in which all factors affecting the state of the filter are reflected. Accordingly, the state information may be a numerical value derived through a specific equation, and may be briefly expressed as a grade.

On the other hand, the state information may be affected by the use environment of the filter. Accordingly, the filter detection unit 102 may detect the filter status information in connection with the air detection unit 110 .

For example, the air sensor 110 may include a dust sensor 113 , a gas sensor 114 , a temperature sensor 115 , and a humidity sensor 116 .

On the other hand, since the air sensing unit 110 detects the indoor air quality and the outdoor air quality, respectively, the filter management solution may be more accurate. For example, when both indoor and outdoor air quality is worse than when indoor air quality is bad and outdoor air quality is good, the frequency of use of the air purifier 100 may increase. The filter 101 included in the air purifier 100 with increased frequency of use may easily deteriorate.

In addition, various sensors included in the air sensing unit 110 may have different sensitivities or sensing ranges according to pattern information and air cleaning solutions. For example, since the temperature and humidity can be changed irregularly by the air cleaning solution, the control unit 130 receives the control signal to organically control the sensitivity or detection range of the temperature sensor 115 and the humidity sensor 116. can For example, since the number of people around may suddenly increase through pattern information, the controller 130 may receive a control signal to organically control the sensitivity or detection range of the gas sensor for detecting the concentration of carbon dioxide.

Also, the solution determining unit 230 may receive attribute information and event information of a space in which the plurality of air purifiers 210 are disposed, and determine a filter management solution based on the attribute information and event information. For example, the solution determining unit 230 may receive a result of a questionnaire from the user through the terminal. Here, the survey result may be attribute information and event information of the space.

Here, the attribute information of the space may include local information, residential environment, household information, product use information, life pattern, and the like. For example, the attribute information of the space may be determined through an interview between the manager of the air purifier management system 200 and the user of the air purifier. The determined attribute information of the space may be input to the solution determining unit 230 by an administrator.

Here, the event information may include outdoor weather, construction, accidents, and the like. For example, if the humidity around the air purifier is high and it is raining outdoors, the filter management solution may increase the probability of replacing the filter.

The solution providing unit 240 may provide a filter management solution to the user of the air purifier. For example, the filter management solution may be transmitted to each of the plurality of air purifiers 210 through the solution providing unit 240 . For example, the filter management solution may be provided as an air purifier and other items (such as a terminal) through the solution providing unit 240 .

Meanwhile, the solution providing unit 240 may provide a filter grade, data, and the like to the user in real time. Also, the solution providing unit 240 may provide a user's action guide according to the filter state in real time. In other words, a filter management solution can be a complex guide to improving air quality. In addition, since the solution providing unit 240 provides the filter management solution to the user, the lifespan of the air purifier may be extended and the use of the air purifier may be increased.
