This purifier is not very wide and it is still against deep enough, there is still quite discreet by its white color and its lines well-rounded.
It is really ... bit noisy compared to other models of course. If you have never had a purifier must not expect to not hear it at all. In short, I find the very low noise level and we forget very quickly. It analyzes the air quality and adapts its purifying power (3-speed) accordingly. He once mode, night mode and a timer (timer).
Air quality can feel the difference within minutes. You can FEEL the air is healthier.
I am very happy and I do not regret my old purifier.
