I live in an area with not so great air quality and no AC. We have little air filters inside the rooms, but at night we have to let the cool (and dirty) air inside to cool down the house.
I’d like a solution to blow air in while also filtering it - but aside from one Amazon listing and makeshift solutions with zip ties, I haven’t seen great options.
Any recommendations you have?
Honestly, I’d just throw a decent furnace filter on the intake side of a box fan. Its cheap, effective , and you can easily replace the filter once it gets too grimy.
