Downdraft table

[Syd Lorandeau]

In the process of building a downdraft sanding table and Martin Shupe sent me a great set of plans. Next problem, I hear you can make it so it does two jobs, a downdraft table and when you are not using it for that let it run as an air purfier. Where can I find info on filters types necessary to do this.
Thanks,

Syd,

Glad you liked the plans. I don't know about filters, but I think someone here will. I'll be monitoring to find out as well.
