This is a shop made air cleaner that I made using an old furnace squirrel cage blower. I built the box out of 3/4 plywood and mounted the squirrel cage inside. I then made frames that would hold a standard size throw away furnace filters. I put 2 on the intake side of the blower and one on the exhaust side.
When It is time to change I throw away the first intake filter move the other 2 forward and put a fresh one on the exhaust side.
I have calculated that this blower will exchange the air in the shop about every 8 minutes.
I got the blower for free and had most of the other material around the shop so maybe have about $60 bucks invested for a very effective air cleaner that does a nice job when I am sanding or making a lot of sawdust.

How do you switch it on and off?
I am curious if it’s possible to hook one of these up to your equipment switches to cycle the air while your running your sanders etc…

I have a timer in the outlet that I plug it into and have it set to run a couple of hours every day but if I am sanding there is a switch on the timer that will turn it on to run continuous. In the summer time when the AC is running I set the timer to run more so that I don’t get so much fine dust through the AC. I also place a furnace filter in front of the AC to catch fine dust as well.

Very cool—I’m going to build one of these for next fall/winter, unless I get too spoiled by working in AC this summer. (My garage pipes are exposed, so it’s either sweating/dripping pipes or a cool garage . .. hmm . . )

Very nice! I’ve been thinking about building something like this for a while. Buying an air cleaner seems like such a ripoff for how simple they really are. I just need to get my hands on a furnace blower to design it around… wish I knew someone who works in HVAC.
Within the last week I’ve come to the realization that I’m allergic to walnut dust. I had a couple reactions where my face turned all red before I made the connection that it happened after I was working with walnut. From what I’ve been reading, a reaction to one wood means I’m susceptible to reactions from others, so I really need to start taking more precautions than just using a dust collector. Something like this needs to be added to my shop sooner than later.
Thanks for posting.

Nice job! I am thinking of building one of these.
How did you get it up to the ceiling, and how did you mount it?

AJ,
At the time I was mounting this I had just finished putting up the OSB on all of the walls and ceiling and had borrowed a panel lift from a friend.
I just put a piece of plywood on the panel lift and then set the air cleaner on top of that and cranked it up to where I wanted it and screwed it to the ceiling. I made sure that 4 of the screws went into the 2×4 ceiling joists that I had run and then put in about 8 more directly into the 7/16 OSB panels.
Hope this helps.
Gene
