Negative Positive
Title: very disappointing
Review: I bought this purifier for the room that my cats' litter boxes are in. I was buying a replacement for a purifier I had which got lost in a move, and the model I had previously bought is no longer made. I wanted a model that was small (I live in a one bedroom apartment), quiet, and can keep the dust from the litter boxes under control. I've owned this one 6 months and while it started off quiet it no longer is. Not only is it loud but the loudness isn't constant; instead of a constant whirring it sounds more like whirwhirwhir. Also, and most importantly, everything in that room stinks like dust. I essentially threw money buying this one; I am now shopping for a new purifier.
Is the review positive or negative?
