I’ve seen posts about people using box fans with a filter to help clean air in spaces/workshops all the time. Here is my version and was somewhat based off one woodshaver posted. I will see how it works. I’m not a analyst so I don’t know what CFM or whatever it might do. I can tell you that if you have have smokers over to watch Sunday football it really helps the garage from becoming a smoke box when it’s cold and the garage door is closed. You can see the smoking lounge in the background. haha
It’s simply 1 board of pine lumber from HD that cost $7.33, a box fan that I had ($20 probably), and a furnace filter with a HD rating of 9 ($15). Who knows what filter I’ll continue to use.
I just used double rabbet joints, put a filler strip for the filter to sit on and hold the fan in place, and made a slot for the lighting deflector that I had sitting around for behind the filter – to make it more pleasing to the eye!
The finish is just 1 part shellac mixed with 2 parts denatured alcohol for a sealer. I then used some Shewrin-Williams wiping stain I had leftover from the rocking chair refinish I posted last year. I found a can of spray semi-gloss poly on the shelf and sprayed on three coats for the final finish.
I might put a door on the filter opening and I need to do something about the cord. It’s hooked up to my outdoor Christmas light timer for now. The top is screwed on so that everything can be removed easily.
Think that’s it. – Drew
