The AP-1019C is a compact air purifier that can cover a range of 33㎡. It has a specialized filter that users can conveniently manage themselves. Dust collection and deodorizing filters are installed on the front cover and detach when it is opened, so there is no need to detach each one individually to clean the inside as in previous purifiers. Even more convenient is the removal system for the pre-filter which must be cleaned often; this can be easily slid out of the top without any need to remove the front cover. An LED shows when the filters need to be replaced and when the pre-filter should be cleaned.
