Deodorizer HDS-302G PLAZION I used this in my living room for about 3 years, but I'm selling it because I bought another air purifier. I kept it out of the way, so there are almost no major scratches on the exterior, and I think it's clean (see photos). I've washed the dust-collecting filter about twice, and it's a little worn, so if you're concerned, please purchase a new one separately.
