<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;">I have a air cleaner hanging from my shop ceiling and I use it all the time. but I also have loud music and ear protection on so I don't really notice it. when I'm sketching or laying out stuff I just use the remote and turn it off. I've never found it to be more annoying than blowing various wood species out of my nose.<br><br>the problem with relying on a shop vac or dust collection system hooked up to your tools is it only gets the majority of the dust. those fines don't get past the filter, they are just propelled into your work space willy nilly, so having an air cleaner that can do lots of air changes rapidly takes up the dust collection slack. with a small shop like you propose, you will rarely, if ever, notice any dust in the air while running a circulating air filter. <br><br>If you have a shop vac hooked up to your tool
then I'd bet you wouldn't need a respirator until you apply finishes.<br><br>It would be nice to have a voc filter for the unit.<br><br><br>"Time makes more converts than reason."

I want to be able to close the door and keep dust out of the rest of the house. I'll be using mainly small tools, and a small table saw and perhaps a compound miter
saw. So a shop vac (along with whatever comes with the tools) will be my main dust collection system, and I'll be using a respirator when doing my cuts, routing and sanding.

Others on the web seem to say that a second fan, to draw in supply air, is necessary.
