No idea why this thread creapt into my head, but bczoom did you ever decide on an air filter?
Yep. I picked up a Honeywell 50250
Here's a link, with product info copied below.
So far, I'd say it's working pretty decent. It's not as if you're never going to have to dust the wood in the room but the amount of dust from the wood stove is way down. There's a 3-speed fan which is nice. If I've just emptied the ashes or something, I crank it up to high for a couple hours afterwards. We put it on the low setting when in the room. At it's low setting, the fan is about the same volume as the woodstove fan(s). I got from HD but looking on the internet, better pricing is available.
