Is there a portable type exhaust device e I can use in my basement for woodworking?
 

I only have one tiny window down there- we just moved into this house and are only renting. This window seems sealed shut. Is there some sort of a portable exhaust device I can use while working? Unfortunately my saws don't have the exhaust bag to hook up to a shop vac. Thanks. :help:

This might be something to read. I haven't used one so I don't know if it works. And welcome to the site.

Thanks! Looking into that site now.

Years ago some guy tried to sell me a big industrial unit. He claimed it would make the dust fall to the floor. I never bought it and I'm not sure this is the same type if system.
