This is the new air circulator I just build about 6 weeks ago. I was waiting to post to see how well it works and it is as good or even better than some that have been in shops I have worked in. It cost about $110 all together and all it is is a box out of ultra light mdf and a squirrel cage blower from a hvac. You mount it in the box and frame around the blower. The blower is going to suck air to the circulator and you put a filter at the one end to catch the dust! I will fill in more but running out to go camping! Any questions please ask and I will answer. Sorry first picture is not up right.

I have about the same amount of money into my shop made air cleaner. It really is a simple build. I still need to install it though.

I have three of these in my shop that I made. Two were from plywood I had in the shop and I bought plywood for the third one. At first I used the washable electrostatic filters (two on each box) but they allowed too much dust through them. I soon discovered the are not as efficient as the disposable paper pleated filters.

Way to go Brian,
I had to replace my AC/furnace this past Spring. I kept the furnace unit and squirrel cage fan, just for such a project. I need to get moving on my version ASAP.

Very Nice. My filter is a $16 box fan with a standard and then a HEPA filter duct taped to it. Not sure how effective it is. But it does collect dust.

Yah, I use the box fan with the two filters too … collects alot of very fine dust. I added a gutter at the botom so the lose dust falls into it, when there is a layer of dust in there it’s time to clean/change the filters.

Box fan, bungee cord and furnace filter! Wife saw it on TV on a home remodeling show. It works! I vacuum the filter with a Shop Vac frequently.

I use something similar in my finish shop—nice big squirrel cage fan inside a box with double filters on it – a looser filter on the outside, heavier on the inside. I just picked up a smaller unit a couple weeks ago and want to build one for over my workbench in the home shop where I woodburn and use the dremel a lot. I love to burn but hate smelling like a campfire at the end of the day and I think this would pull the smoke up and away without cooling my pens.

Like it. Just built one myself from a free HVAC motor and squirrel cage and case. Used left over scraps of 3/4 ply. I put my on a shelf over by a wall. If I put mine up on the floor joist, the family room above would feel the vibration.
