I have a couple of blu air purifiers. They really cut down on the amount of dust in the room. We used to have to dust weekly, in the rooms where we have the purifiers we dust maybe every other month now and you can't tell a difference.

I don't know why it's so useless against dust. Maybe we have more coarse-grained dust which quickly falls down on the ground.
- malfist 5y agoThe blu air filter has a prefilter specifically for dust and it gets filthy. That has to get washed in the laundry regularly. Maybe some combination of that, it's cfm's and placement might make a difference?
- s0rce 5y agoI have 2 coway units in a ~800sqft apartment and still have tons of dust but I open the windows a lot when its not smoky and I have a dog so who knows. The pre-filter does trap a lot of dust so there is obviously some (maybe minor) reduction.
