Yes, its quiet, so quite our 3 year old daughter kept pushing the fan button to "turn it on." We set this up in our bedroom and it has been perfect, I love the fact that it shows the air quality with different led colors, and that it knows when we are going to sleep and goes into  eco mode. Its so quiet I keep forgetting its there. I love the design, its sleek and modern, but also short enough that it's not a towering monolith. I feel like i'm breathing better and I'll attribute that to the air purifier, so Im happy!
