Levoit Air Purifier ~20 tatami (approx. 360 sq ft) LAP-C301S-WJP White, main unit (filter included) + instruction manual Purchased in 2022 for pollen対策 (pollen countermeasures) I liked both the performance and design and used it for about a year, but I stopped using it when I moved and have been storing it. Non-smoker, no pets The filter is as it was when purchased. Dust on the filter has been cleaned with a vacuum cleaner. *There are some black scratches and stains on the surface, but it is in relatively clean condition. Instruction manual included. No original box.
