You need a bigger air purifier. :) I have one that will definitely suck in dust from the other side of the room.
I have one that claims "Circulates the air 1x per hour in 743 square foot rooms and 4.8x per hour in 153 sq. ft rooms". My room is 180 square feet (12x15).
The concept itself doesn't make sense to me. You've got a single box that both sucks in air and blows it out. It would seem to me that this just creates vortex around the box itself with some minimal air movement in the rest of the area.
A proper air purification system would need to be part of your home's central HVAC system where it's been engineered to suck in the air from one side of a room, filter it through the system, then blow it back out on the other side of the room. And / or several smaller air purifiers strategically placed within a room.
I've done a bit of searching and surprisingly have not been able to find a rally good study. This would seem easy enough to qualify with some knowledge of fluid mechanics. I found this video https://www.youtube.com/watch?v=NinsW8f2ABk The room is about a third the size of my room and the purifier is about 50% larger. The in/out design of this device is dramatically different from mine. I have a hunch that the consumer (Amazon) air purifier market is mostly garbage.
You are correct the volume is how much air it can process and not a guarantee it will do your actual space. You definitely will get overly air cycled areas and deadzones. You may find more dust settles in certain areas now. Without ducting, one thing you could try it setting up an ossicilating fan elsewhere to try to randomly kick more air into the flow of things. By doing this it will get more dust into the air at first until it can be drawn into a filter.
