I want to ask, which air purifiers reduce dust - not only in the air but also on the floor. Got such thing? I've an air purifier ioniser (Amcorp now discontinued) - I notice I need to vacuum more as it sets the dust down on the floor and worktops and shelves... Need to dust more...

Sorry mine was Amcor and not Amcorp brand which was well known at one point in time. But it has now been discontinued. It was meant to be an air purifier and not just an ioniser but I notice more dust settling down for my cleaning and personally I don't think there'll be an air purifier which purifies air as well as floor. If there's one available pls share the make of it.
