I have a Mitsubishi dehumidifier which is supposed to filter the air but this thing is next level. The air smells fresh at night and my asthma is way better. I can see the humidity level and turn on the dehumidifier as well if I need to do so. Getting it to work with the app took time but I just leave it on automatic all the time even when I'm away for a few days. Dust under my bed also seems less.
