Existing air cleaners cant provide the feedback of cleaning. In addition, users have to wash a pre-filter of the product every month. This behavior mars the pre-filter and it causes a decrease of performance. For this problem, companies give extra pre-filter to users and the user should change it by users own. On the other hand, Air-Documentary applies a rolling film to the structure of pre-film and the user tears the film that be taken down automatically and throws it away instead of washing and changing. In addition, the Air-Documentarys film visualizes the feedback of cleaning, so the user can see the result of cleaning every two weeks.
