Purchased from the official online store in February 2024. A brand new, unopened main filter is included, so you can use it with like-new specifications as soon as it arrives. The influenza season seems to have already begun this year, so this item will be a great help in the coming months! ◾️Manufacturer: Blueair ◾️Product Name: Blueair Protect 7310i ◾️Year of Manufacture: 2023 ◾️Applicable Floor Area: ~48㎡ (29 tatami mats) ◾️Body Size: Width 270 x Depth 270 x Height 610 (mm) ◾️Usage Period: Approximately 1 year (late February 2024 - mid-March 2025) 【Included Items】 All items in the second image. ・Power cord ・Instruction manual ・Replacement filter x 1 box 【Condition】 ・No noticeable scratches or stains, and I believe it has hardly been used. ・Operation confirmed.

To prevent damage, I will wrap the entire item securely with cushioning material (bubble wrap) and ship it in a cardboard box. ★Instant purchase is OK★ Please understand that there may be minor oversights as this is a personal inspection. Although it is in very clean condition, please consider purchasing if you understand that it is a used item.
