It has been stored away since the spring of 2016, but the operation has been confirmed before listing. The filters are still the same as when purchased, and I don't think they show any signs of use. However, please understand that they are still used items. ◼ The deodorizing filter is washable and does not need to be replaced. ※ Since the operating time was short and there was no smoking, it has been left as is. ◼ The dust collection filter does not need to be replaced for 10 years, according to the instruction manual. Washing is strictly prohibited, and for the listing, I have taken care to lightly vacuum one side to remove dust.
