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?
Filters do slow down air flow.
filters on the output side should still strain the fan motor, no?
No, static pressure against a pump (which technically a fan is) is much less stressful against the motor than limiting the supply is. It’s easier for the fan to push against resistance than it is to pull air through resistance.

geesh where do you live that the air quality is damaging to fan motors so often?
