Works very well and has a slick, clean design, which is what I was after. It's also not massive and not tiny, so a good middle ground for use in a room. It reacts well to particulates (I didn't realise frying generated so much, but the particulates must've travelled upstairs and the purifier worked overtime to clean the air). The night function is good, although a bit of light is still emitted from the display panel. A remote would have been a nice touch, but not essential.
