I have a Mila downstairs between lounge and kitchen. It definitely pulls stuff in, as the "sock" I put over the filter is caked when its time to change the filter.
Had a smoke incident with log burner when the flu was especially cold. Entire lounge filled with smoke. I pulled the Mila over and cranked it to maximum, it cleared up and smoke and smell pretty well.
It is noisy when it's going at higher speed, but then it's CADR is 460 cubic meters an hour. 3x that of the Levoit 300's. I often just leave it on manual slow speed, but you can't push large volumes of air through filters without making a bit of noise. Any silent filter is going to be doing virtually nothing.
It does detect things like toast, opening log burner door, frying bacon/pancakes etc.. The Particulate indicate goes up considerably.
I use the Rookie Parent filter which is Hepa 12 plus some granulated carbon to absorb odours.
It doesn't prevent the need for dusting. Does it reduce it? Well it pulls stuff in, so it must be, but it's not like it's noticeable that much. I use it mostly for removing cooking odours (open plan downstairs) and keeping on top of particulates with having a log burner.
Putting all your washing through a condensing dryer that collects lint with help reduce dust in the house, which is mostly clothes/towel/bedding broken fibres.
Tempted to get a Mila-mini for upstairs.
