Air purification systems

From: Donald Farren <dfarren>

Does anyone have experience with relatively small, free-standing air
cleaners (of the sort that Sears sells)? They are advertised as
"99.97% effective in removing most airborne particles, including
pollen, smoke, mold spores, and pet dander". Question: How effective
are they in trapping fine dust particles, like "book dust"?
