I'm selling this to organize my room. The included items are: ◯ Main unit (with used filter) ◯ 1 new filter ◯ New wall mounting angle ◯ Instruction manual ◯ Power cord 【Long-lasting filter】The "electrostatic dust collection" system, which excels at removing cigarette smoke, prevents filter clogging and avoids the premature performance degradation common with commercially available products. It provides high-level air purification for a long time. 【Thorough removal with multiple stages】It removes cigarette odors with a multi-stage system consisting of two filters, a high-performance catalyst, and an ion generator. The patented columnar titanium oxide photocatalyst decomposes harmful substances about three times faster than conventional methods! Regarding the condition of the item, I have checked it as much as possible at the time of listing, but there may be oversights as I am an amateur. If you have any questions or concerns, please feel free to comment and I will respond. If you wish to purchase, please check my profile beforehand.
