Any suggestions on an air purifier? Something low powered and for a small home?

A "box fan" (20" x 20") and a furnace filter (MEV 13 or higher, or "1900" or higher (different brands use different scales).
For the premium filters, I could only find 3M (the non-American brands did not come in the right size/quality combination)).
I will make a Corsi-Rosenthal device out of these, when the air gets bad enough.
In Bells Corners, I don't find the air as bad as what others in Ottawa area are reporting. Yet.

@bjb Yeah, I was wondering if there was another option worthwhile.

@mariellequinton My impression after small amount of research is that this device will be more effective (by multiple times) and much cheaper than little table top ready made devices. Also they can be decorated with contact paper or whatever and do not have to look super ugly.
I just offer my observations, and have boosted your question for more crowd-sourced info.

@bjb A built-in sensor so that it can run automatically is a big plus. The box fans are kind of loud and big, which is why I wondered if it's worth to to spend more on a commercial product.

My place is small, and I don't want to make a full 20"x20"x20" cube. I am just going to tie one filter to the back of the fan and call it done. So it will be 20"x20"x (thickness of fan + filter). It should clean particles out of the air, even so. I can put it in a room and clean the air there if things get bad.

@bjb @mariellequinton I ended up going with one of these. I've done the Corsi-Rosenthal thing in the past but didn't want to deal with the upkeep.
