Topic tags/keywords: power carving box fan air filter

Can anyone tell me what the cfm rating should be for a 20” box fan filter? I am wanting to use this fan while I power carve.

Thanks for you help

I have a cheap 20” Lasko from Home Depot the mfg claims up to 2500 cfm on high. I have never measured to see if its true.
