I bought it used on Craigslist.. the brand is EcoPlus Carbonaire. I don't know the model though since I bought it used.
After looking at the manual that came with it.. I am starting to think I have been running it backwards... The person who had it before me just had it set up with the fan blowing in so I thought that is how it should go.
I looked at some similar ones online and they all have the fan sucking in the pictures...
It makes sense because by blowing into mine, I don't even need the prefilter on the outside because it is only slowing down my CFM.
Now you got me thinking I should make mine suck in, the fan just flips over no problem....
