That drywall dust collector trick actually works

I got tired of drywall dust coating every surface in my house during a small bedroom reno. Someone on here mentioned cutting a box fan hole in a cheap furnace filter and taping it to the intake. Tried it last weekend on a 12x14 room and it caught probably 90% of the floating dust. Anyone else use this setup or have a better DIY filter rig?

Saw that trick on a home improvement blog last year.

Wait, you cut the hole in the filter, not the fan, right?
