no previous part Part 1 of Clean shop air series no next part

In looking around the web, I came across some articles about using a 20” box fan and a standard 20” by 20” furnace air filter as a air cleaner for your shop. My work area is only a 10’ by 12’ so I thought that would do the trick for me, and for less than buying one. Between the box fan and the air conditioner, I live in Glendale AZ so Ineed air in the summer, with a special filter in it, I expect they should hold down dust pretty good. I expect that by the time I am finished I should have less than $30 invested.
Has anyone out there done this, if so, does it work?
Thanks

I’ve done just this. I use two filters, the outer to collect the large “dust” and a finer one to really clean the air.

I like that idea of the two filters. Think I will revamp my thoughts.
Thanks

I did it at first, worked okay for me, but didn’t move enough air in my 18×20 shop for my tastes… In your 10×12 you should be more than fine…

Box fan $5.00 at Goodwill or a Garage sale. (I see them all the time around here)
Filtrete 20×20 MERV 11 or better filter $16.00
Roll of duct tape $5.00

Total spent $27.00 before taxes…

Pretty hard to beat those kinds of numbers.

I have one as well. I use a course outer filter, but I recommend buying the paper one for inside. Removes more dust. My shop is 14×20 and I like it.
I also use mine to cool in summer, I have made a tube vent along ridge inside with vents blowing down.
