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?
If it’s just one room, use a tower air purifier. Mine is set up in my workshop at a window. I cut a piece of fiberboard to adapt the purifier to the window frame, but cardboard works.
I like this method better than the box fan/filter combo because it provides greater air flow and removes pretty much everything with the HEPA and carbon filters. It’s saving my sanity right now with all the pine tree pollen and smoke from debris pile burning.
For a whole home, place a window fan in one room pointing out. Then put air filters in the windows of other rooms. This has the benefit of keeping the noisy fan in an unoccupied room while you’re trying to sleep. Alternatively, if you have an attic, you can get a fan that fits the attic access. This works better because you’ll be cooling your attic as well. You can also consider a dedicated attic fan which can knock 10 degrees off the inside temperature on a hot day.
