Made in 2017 SHARP Air Purifier FU-H50W, floor-standing/tabletop type Equipped with high-density Plasmacluster 7000 Suitable for rooms up to 23 tatami mats (approx. 38 square meters) Instruction manual Used for about 2 years after purchase, then cleaned the filters, etc., and stored in a closet. The main body seems to have slightly discolored, but I don't think it's very noticeable. There are no noticeable scratches or stains, but there is some light soiling on the surface (Photos 8, 9). The filters have been cleaned and feel clean, but if you are concerned, please consider replacing them. Operation has been confirmed. * No pets or smokers.
