So I looked up an old post about attaching an air filter to a box fan for a DIY air purifier. I read enough to figure out that it won’t work to reasonable efficiency.
My question is, how well will a vent filter work to merely keep dust out of my box fan? I just finished taking apart my box fan to clean the dust out, and I’m not crazy about this dust buildup and the dust particles likely blowing in my face when I use it. Any tips on adding a filter to my box fan, or is it as easy as zip tying a $10 air filter to the back of my fan?
