Air pollution does not only come from outdoors but also from indoors. Data from WHO shows that every year 3.2 million people die prematurely due to diseases caused by indoor air pollution. This pollution comes from cigarette smoke, use of traditional kitchen stoves, household cleaning products, mold, animal dander, and so on. Therefore, we need an air purifier that can filter various pollutants, because we spend more time indoors. Microalgae are one of the largest oxygen-producing and carbon dioxide-absorbing microorganisms on earth many studies have proved. So that microalgae have the potential to be used as part of overcoming air pollution. In this design, the aim is to combine the existing features of conventional air purifiers with microalgae, in a device whose design integrates well with the interior of the room. By still considering the ease of maintenance of tools and microalgae. With the aim of overcoming air pollution and improving indoor air quality while still paying attention to good design aspects.
