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 thought the charts went the other way around...the box fan did okay,
but was beaten by the dedicated systems.
