I was in HD this afternoon after work and they have the Rigid AF2100 air filtration system on clearance for $69 down from $99.

The item number for the unit is 648846003139

Check out the price of replacement filters. Air cleaners can be like computer printers, they sell the cheap, then make a killing selling you the ink cartridges.
Check the microns it captures you qant something like .5 or 1 micron.
If you figure the cubic footage of your shop Lenght x Width x Hieght, then look at the CFM rating fo the Air Cleaner, take the CFM multiplied it by (this gives you cubic feet of air moved per hour) 60 then divide that number into the CuFtage this will tell you how many air changes you will have per hour. You want to see around 20/hr.
If I made it to complicated you can give me the data and I can crunch the numbers for you, I’m still half asleep it’s 4 in the morning. I’ve been doing this design stuff for about 30 yrs so just let me know if you need any help.

It’s a racket like books in college. I made my own to use standard size furnace filter because they are so much cheaper. I went to a heating and cooling shop to get the fan and motor because they always have them laying around and are willing to get rid of them very cheap. $20.00, scrap wood and two filters for $5.00. It does the job. I can get 1 micron filters for a bit more and what I do is put one 30m and a 1 m and that works.
