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?
Maybe you could make a Corsi–Rosenthal Box. They’re pretty easy and cheap. It’s basically just a fan, a filter(s), and some tape.
Though it would be significantly less effective when bringing in outside air than just filtering inside air.
