Default Air Filtration review in Wood magazine

I just wanted to verify that I read those charts correctly....the
regular box fan with a furnace filter duct taped to it out performed
like 95% of the dedicated air filtration systems???

I read that same article and my own experiences don't agree.

My box fans with filters are cheap, portable, and much better than
nothing. However, a squirrel cage blower based unit, either shop made
or purchased, clears the air far faster.
