The AP-2021A is a tower air purifier for rooms larger than 50 sqm, designed with the objective of being perceived as a decorative object. Inspired by an architectural structure, it has horizontally running, regularly arranged inlets, which give the unit an uncluttered aesthetic. The air flap on the top with its touch functionality allows the user to channel airflow in the desired direction. Two of the four sides can be equipped with special filters, such as for pets.
